Medullocytoma

Medullocytoma is a rare tumor that grows inside the brain, most often in the back part of the brain (posterior fossa/cerebellar area). It belongs to a group of tumors that can behave aggressively, meaning the cells can grow fast and may spread through the cerebrospinal fluid (CSF) pathways (the fluid spaces around the brain and spinal cord). Because it sits in a tight space, the tumor can block normal CSF flow and raise pressure inside the skull, causing headaches, vomiting, and balance problems. Treatment usually needs a specialist team (neurosurgery + radiation oncology + pediatric/medical oncology + rehab), and plans are adjusted by age, tumor location, and risk features. Cancer.gov+1

A medulloblastoma is a fast-growing cancer (malignant tumor) that usually starts in the cerebellum, which is the lower back part of the brain. The cerebellum helps control balance, coordination, and smooth body movement, so a tumor here often causes walking and balance problems. Cancer.gov+2Cleveland Clinic+2

Medullocytoma care is typically built around three big goals: (1) remove or shrink the main tumor, (2) control or prevent spread in the brain/CSF, and (3) protect brain function and quality of life during and after treatment. Most modern plans use a mix of surgery, radiation therapy (in many patients), and chemotherapy, plus strong supportive care and long-term follow-up. Cancer.gov+1

In many conversations, the word “medullocytoma” is used to mean medulloblastoma. In modern medicine, medulloblastoma is the standard name used in major cancer and tumor references, so this article explains medulloblastoma in clear, simple words. Cancer.gov+1

Medulloblastoma can sometimes spread through the cerebrospinal fluid (CSF), the clear fluid that flows around the brain and spinal cord. Because of this, doctors often check the spine and CSF during testing. In the WHO brain tumor system and in major cancer guidance, medulloblastoma is treated as a high-grade (WHO grade 4) embryonal tumor, meaning it grows quickly and needs urgent specialist care.

Other Names

Medulloblastoma (most used medical name today). Cancer.gov

CNS embryonal tumor (of the cerebellum/posterior fossa) (because it is an embryonal-type tumor that typically starts in the back part of the brain). Cancer.gov+1

Posterior fossa primitive neuroectodermal tumor (PNET) (older wording; many modern sources no longer use “PNET” as the main name, but you may still see it on older pages). Wikipedia+1

Types

Doctors may describe “types” in two main ways: (1) what the tumor looks like under the microscope (histology), and (2) what the tumor looks like by gene/molecular pattern (molecular type). PMC+1

• WNT-activated medulloblastoma (a molecular type with WNT pathway changes). PMC+1

• SHH-activated medulloblastoma (TP53-wildtype) (SHH pathway active; TP53 not mutated). PMC+1

• SHH-activated medulloblastoma (TP53-mutant) (SHH pathway active with TP53 mutation). PMC+1

• Non-WNT / Non-SHH medulloblastoma (often called Group 3 and Group 4) (molecular groups not driven by WNT or SHH). PMC+1

• Classic medulloblastoma (a common microscope pattern). PMC

• Desmoplastic/nodular medulloblastoma (has nodules and a “fibrous” pattern). PMC

• Medulloblastoma with extensive nodularity (MBEN) (often discussed in very young children). PMC

• Large cell / anaplastic medulloblastoma (cells look more abnormal and aggressive under the microscope). PMC

Causes and Risk Factors

In simple words: most of the time, doctors do not know the exact cause. But research shows gene changes inside tumor cells and a few inherited (family) syndromes can raise risk. Below are “causes” explained as known risk factors or known biological drivers. Cancer.gov+2Mayo Clinic+2

1. Unknown (sporadic) cause in most people: For most patients, medulloblastoma happens without a clear outside cause that anyone can point to. Cancer.gov+1

2. Random gene changes in a single cell: Cancer can begin when genes that control cell growth change and a cell starts dividing too fast. Cancer.gov

3. WNT pathway activation (tumor gene pattern): Some tumors grow because the WNT/β-catenin pathway is switched on by gene changes (a driver of that tumor type). PMC+1

4. CTNNB1 gene changes (often in WNT type): CTNNB1 mutations are strongly linked with WNT-activated medulloblastoma. PMC+1

5. APC gene changes (linked to WNT type and some inherited cases): APC germline changes can be linked with a medulloblastoma risk pattern similar to WNT tumors. PMC+1

6. SHH pathway activation (tumor gene pattern): Some tumors grow because the Sonic Hedgehog (SHH) pathway is overactive. PMC+1

7. PTCH1 / SUFU / SMO gene changes (SHH pathway genes): Changes in SHH pathway genes can drive tumor growth in SHH-activated medulloblastoma. PMC+1

8. TP53 mutation (in some SHH tumors): TP53 changes define an important SHH subgroup and can affect how the tumor behaves. PMC+1

9. MYC or MYCN amplification (growth-signal “gas pedal”): Some medulloblastomas have extra MYC/MYCN activity, which can push cells to multiply faster. Wikipedia+1

10. Inherited cancer-predisposition genes: Large studies have found extra harmful germline mutations in genes like APC, BRCA2, PALB2, PTCH1, SUFU in some patients. ScienceDirect+1

11. Gorlin syndrome (nevoid basal cell carcinoma syndrome): This inherited syndrome (often involving PTCH1/PTCH2/SUFU pathway genes) can raise medulloblastoma risk, especially in some children. MSD Manuals+1

12. Turcot syndrome: Turcot syndrome (often involving APC or mismatch repair pathways, depending on type) is linked with higher risk of certain brain tumors including medulloblastoma. Mayo Clinic+1

13. Li-Fraumeni syndrome: This inherited syndrome (TP53 related) is listed among conditions that can increase medulloblastoma risk. Mayo Clinic+1

14. Fanconi anemia: Fanconi anemia is also listed among inherited syndromes linked with increased risk in some references. Mayo Clinic+1

15. Rubinstein-Taybi syndrome: Some clinical references list Rubinstein-Taybi among inherited syndromes linked with higher medulloblastoma risk. Mayo Clinic

16. Young age (childhood): Medulloblastoma happens most often in children, so being a child is a strong risk factor compared with adults. Mayo Clinic+1

17. Family history of cancer-risk syndromes: If a family has known inherited syndromes that raise cancer risk, medulloblastoma risk can be higher. Mayo Clinic+1

18. Developmental cell growth errors in the cerebellum: Many experts describe medulloblastoma as linked to mistakes in early “immature” brain cell growth and development, especially in certain molecular groups. Wikipedia+1

19. Chromosome and copy-number changes in tumor cells: Some tumors show DNA copy-number changes (extra/lost pieces) that help define risk groups and behavior. Wikipedia+1

20. Prior head/brain radiation exposure (rare risk factor): Some clinical discussions mention earlier radiation as a possible risk factor for later tumors, though most cases still do not have a clear environmental cause. Relainstitute+1

Symptoms

Symptoms often happen because the tumor is in the back of the brain and can also block normal CSF flow, raising pressure inside the head. Mayo Clinic+1

1. Headache (often worse in the morning): Pressure changes inside the skull can cause headaches, and morning headaches can happen because pressure can rise overnight. Mayo Clinic+1

2. Nausea: Brain pressure and vomiting centers can be triggered, causing nausea. Wikipedia+1

3. Vomiting (sometimes repeated): Vomiting is common, especially when pressure is higher or CSF flow is blocked. Wikipedia+1

4. Balance problems: Because the cerebellum controls balance, a tumor there can make a person unsteady. Mayo Clinic+1

5. Trouble walking (unsteady gait): People may walk with a wide stance, stumble, or fall more often. Wikipedia+1

6. Clumsiness / poor coordination: Fine movements can become harder, like writing or using utensils. Wikipedia+1

7. Dizziness: Dizziness can happen from balance center disruption and pressure effects. Wikipedia+1

8. Vision changes (blurred vision): Pressure and nerve effects can disturb vision. Wikipedia+1

9. Double vision (diplopia): Nerves that control eye movement can be affected, causing double vision. Wikipedia+1

10. Abnormal eye movements (nystagmus): Some people develop “shaking” eye movements when trying to focus. Wikipedia+1

11. Tiredness / sleepiness: Ongoing pressure, poor sleep, and the body’s stress response can cause fatigue. Wikipedia+1

12. Irritability or behavior change (especially in children): Children may act differently, become irritable, or seem less active when they feel unwell for weeks. Wikipedia+1

13. Loss of appetite / weight change: Long-lasting nausea and vomiting can reduce eating. Mayo Clinic+1

14. Enlarging head size in infants: In babies, raised pressure can sometimes show as a growing head size because skull bones are not fully fused yet. Merck Manuals+1

15. Back pain or nerve symptoms (if spread to spine): Because medulloblastoma can spread through CSF, symptoms may sometimes involve the spine, which is why doctors check the spinal area. Cancer.gov+1

Diagnostic Tests

Diagnosis usually uses (1) exam, (2) imaging like MRI, and (3) tumor tissue testing. Doctors may also check the spine and CSF because the tumor can spread through CSF. Cancer.gov+2Mayo Clinic+2

1.  General neurological exam: The clinician checks reflexes, strength, sensation, speech, balance, and how alert the person is. This helps show which part of the brain may be affected. Mayo Clinic+1

2. Cranial nerve exam: The doctor checks eye movements, facial strength, hearing, and swallowing because tumors near the back of the brain can affect these nerves. Mayo Clinic+1

3. Eye exam for papilledema: Swelling of the optic nerve (papilledema) can be a clue that pressure is high inside the skull. Wikipedia+1

4. Coordination and balance screening: A clinician watches posture, sitting balance, and simple coordination tasks to see cerebellum function. Mayo Clinic+1

5. Finger-to-nose test: The person touches their nose and then the examiner’s finger. Shaking or missing the target can suggest cerebellum problems. Mayo Clinic+1

6. Heel-to-shin test: Sliding the heel along the opposite shin checks leg coordination. Trouble can point to cerebellar dysfunction. Mayo Clinic+1

7. Tandem gait (heel-to-toe walking): Walking in a straight line heel-to-toe is a simple way to test balance and coordination. Mayo Clinic+1

8. Romberg test: Standing still with feet together (eyes open/closed) helps check balance systems; unsteadiness can support a cerebellum/balance issue. Mayo Clinic+1

9. Surgical biopsy (tumor tissue sample): A piece of the tumor is removed (often during surgery) so a specialist can confirm the exact tumor type. This is a key step for a true diagnosis. Cancer.gov+1

10. Histology under the microscope: A neuropathologist looks at tumor cells and patterns to identify medulloblastoma and its histologic variant. PMC+1

11. Immunohistochemistry (protein markers): Special stains can highlight proteins that help classify the tumor more accurately. PMC

12. Molecular subgroup testing (WNT/SHH/non-WNT non-SHH): Modern diagnosis often includes molecular typing because it can guide risk grouping and treatment planning. PMC+1

13. DNA methylation profiling: This is an advanced lab method that can classify medulloblastoma very reliably from tumor tissue. PMC+1

14. CSF cytology (checking spinal fluid for tumor cells): Doctors may collect CSF (often by lumbar puncture, in the right timing and situation) to look for tumor cells that show spread through CSF. Cancer.gov+1

15. EEG (brain wave test) in selected cases: EEG is not the main test for medulloblastoma, but it can be used when doctors need to check for seizures or brain-function changes. Medscape+1

16. Auditory brainstem response (ABR/BAEP) when needed: This test measures how sound signals travel through the brainstem. It may help assess brainstem pathway function in some posterior fossa tumor situations. PubMed+1

17. MRI brain (main imaging test): MRI gives detailed pictures and is commonly the preferred scan to show the tumor’s size, exact location, and pressure effects. Mayo Clinic+1

18. CT head (quick scan in emergencies): CT can be used quickly, for example to check hydrocephalus or pressure problems, but MRI is usually more detailed for tumor planning. Mayo Clinic+1

19. MRI spine (to check for spread): Because medulloblastoma can spread through CSF, doctors often image the spine to look for “drop” spread. Cancer.gov+1

20. MR spectroscopy (sometimes as an added tool): MR spectroscopy can add extra information about the tumor’s chemical pattern and may help when doctors are comparing tumor types, but tissue diagnosis is still key. PMC+1

Surgeries (procedure + why it is done)

1) Tumor resection (craniotomy for posterior fossa tumor).
Done to remove as much tumor as safely possible. It lowers tumor burden, helps symptoms, and provides tissue for diagnosis and risk planning. Cancer.gov+1

Done when the tumor sits in a risky spot. It gives tissue diagnosis so the team can choose the right chemo/radiation approach. Cancer.gov

3) Ventriculoperitoneal (VP) shunt.
Done when hydrocephalus persists and CSF can’t drain normally. It routes CSF from brain ventricles to the belly to lower pressure and prevent damage. Cancer.gov

4) Endoscopic third ventriculostomy (ETV).
Done to create a new CSF pathway using an endoscope. It can reduce pressure without a permanent shunt in selected patients. Cancer.gov

5) Ommaya reservoir / intraventricular access device (selected cases).
Done to allow repeated CSF sampling or delivery of medicines in a controlled way, when a protocol needs it. Cancer.gov

1. Keep all follow-up scans and clinic visits. Cancer.gov

2. Report new headaches, vomiting, or balance issues early. Cancer.gov

3. Protect hearing with regular hearing tests during/after platinum therapy. FDA Access Data+1

4. Vaccination planning with oncology (timing matters with chemo). Cancer.gov

5. Infection prevention: hand hygiene + avoid sick contacts when counts are low. Cancer.gov

6. Nutrition plan to prevent weight loss and weakness. Cancer.gov

7. Safe physical activity to prevent deconditioning and falls. Cancer.gov

8. Cognitive/school supports early to prevent long-term learning gaps. Cancer.gov

FAQs

1) Is medullocytoma cancer?
It is treated like a serious brain tumor that can behave aggressively, so doctors manage it with surgery and often chemo/radiation depending on risk. Cancer.gov

2) What is the first treatment step?
Usually surgery (remove tumor or biopsy) comes first, because it relieves pressure and confirms the diagnosis. Cancer.gov+1

3) Why do some patients need radiation to the brain and spine?
Because tumor cells can travel in CSF pathways, craniospinal treatment may be used when spread risk is high. Cancer.gov

4) Will chemotherapy always be used?
Many treatment plans include chemotherapy, especially in higher-risk disease or after radiation, but the exact plan depends on age and tumor features. Cancer.gov

5) What symptoms can happen from pressure in the head?
Headache, vomiting, sleepiness, and balance problems can happen when CSF flow is blocked (hydrocephalus). Cancer.gov

6) Can it come back after treatment?
Yes, relapse can happen, which is why follow-up imaging and symptom checks are important. Cancer.gov

7) Why are hearing tests important?
Platinum drugs like cisplatin can damage hearing, so early testing helps catch problems and adjust care. FDA Access Data+1

8) What are the most common chemo risks?
Low blood counts, infection risk, nausea, fatigue, and organ-specific toxicities (kidney, nerve, hearing) are common concerns. FDA Access Data+1

9) What helps low white blood cells after chemo?
Growth factors like filgrastim or pegfilgrastim may be used in selected cases to boost neutrophils and reduce fever risk. FDA Access Data+1

10) Are “immune booster” supplements safe?
Not always. Some interact with chemo, affect bleeding, or are risky during low immunity—so supplements should be cleared by oncology. Office of Dietary Supplements+1

11) Is melatonin okay for sleep?
It may help short-term sleep timing, but long-term safety is unclear and teens need extra caution—ask the clinician first. NCCIH+1

12) What foods are safest during neutropenia?
Clinics often recommend well-cooked foods, pasteurized dairy, and careful washing to reduce infection exposure. Cancer.gov

13) What is the purpose of rehabilitation therapy?
Rehab helps balance, strength, speech, swallowing, and school skills recover after brain tumor treatment. stjude.org+1

14) Do targeted drugs like hedgehog inhibitors cure this tumor?
They are not universal cures; they may fit only specific tumor biology and are often used in trials/selected relapse settings. FDA Access Data+1

15) When should someone go to the emergency room?
Go urgently for severe headache with vomiting, seizures, new weakness, confusion, high fever during chemo, or severe diarrhea/dehydration. Cancer.gov+1
