Pubococcygeus muscle cysts are uncommon fluid-filled sacs that develop in or near the pubococcygeus muscle—a key component of the pelvic floor. Although cysts in this area are not as well-known as other pelvic cysts, understanding their causes, symptoms, and treatment options is essential for managing pelvic health.
The pubococcygeus muscle is part of your pelvic floor muscles, which support organs such as the bladder, uterus (in women), and rectum. A cyst in this muscle area is a fluid-filled sac that may form as a result of various conditions such as infections, blockages, or trauma. Although pubococcygeus muscle cysts are rare compared to other cysts in the pelvic area, they can cause discomfort and affect quality of life.
Understanding the Pubococcygeus Muscle
Anatomy and Structure
The pubococcygeus muscle is one of the key muscles in the pelvic floor. Here are its main features:
-
Location:
It runs from the pubic bone to the coccyx (tailbone) and forms part of the supportive network of muscles in the pelvis. -
Structure:
It is a thick, fibrous muscle that helps hold the pelvic organs in place. Its strength and tone are vital for functions such as urinary control and sexual function.
Blood Supply
-
Primary Blood Vessels:
The muscle is supplied by small branches of the internal iliac arteries. These vessels deliver oxygen and nutrients that are essential for muscle health and healing. -
Significance:
A robust blood supply supports normal muscle function and is crucial during the repair process after an injury or when a cyst forms.
Nerve Supply
-
Nerves Involved:
The pubococcygeus muscle receives signals from the pudendal nerve and other pelvic nerves. These nerves help control muscle contractions and relay sensations, including pain. -
Role in Function:
Proper nerve supply ensures that the muscle works correctly during activities such as pelvic floor contraction and relaxation.
Functions
-
Pelvic Organ Support:
It helps hold and support pelvic organs, preventing conditions such as prolapse. -
Urinary and Bowel Control:
The muscle plays a role in controlling the release of urine and feces. -
Sexual Function:
It contributes to sexual sensation and performance. -
Stabilization:
The muscle helps stabilize the pelvis during everyday activities such as walking and lifting.
A cyst is a sac filled with fluid or semi-solid material. When such a cyst develops in or near the pubococcygeus muscle, it is referred to as a pubococcygeus muscle cyst. These cysts can vary in size and may result from blockages of small ducts, infections, or other pelvic conditions.
- Characteristics:
- They are generally benign (non-cancerous).
- They might remain small and asymptomatic or enlarge over time, causing discomfort.
- Pathogenesis:
Cysts form when there is an accumulation of fluid due to blocked ducts or inflammation. Over time, if the fluid is not reabsorbed, a cystic structure can develop.
Pathophysiology: How Do These Cysts Develop?
Understanding the pathophysiology involves looking at the underlying processes:
Structure and Formation
-
Cellular Origin:
Cysts may form from remnants of tissue or from the lining of small glands within or near the muscle. -
Fluid Accumulation:
When the normal flow of secretions is blocked—by inflammation, infection, or scar tissue—fluid collects and leads to cyst formation. -
Wall Formation:
Over time, the body forms a capsule or wall around the fluid, resulting in a cyst.
Blood and Nerve Involvement
-
Inflammatory Response:
If a cyst becomes inflamed, the local blood supply increases to deliver immune cells, which can result in swelling and pain. -
Nerve Irritation:
A growing cyst can press on nearby nerves, leading to discomfort, tingling, or pain in the pelvic region.
Functional Impact
-
Pelvic Floor Dysfunction:
Because the pubococcygeus muscle supports pelvic organs, a cyst can alter normal muscle function. This might lead to urinary or bowel control issues. -
Pain and Pressure:
The presence of a cyst may cause chronic pelvic pain or pressure, affecting daily activities and quality of life.
Types of Pubococcygeus Muscle Cysts
While cysts in the pubococcygeus area are less common than other pelvic cysts, they can be classified by their characteristics:
- Simple Cysts:
- These are fluid-filled sacs with a smooth, thin wall and are generally benign.
- Complex Cysts:
- They may contain internal septations (dividing walls) or debris and may require more detailed evaluation.
- Infective Cysts:
- Cysts that have become infected can show signs of inflammation, redness, and pain.
- Endometriotic Cysts:
- Although more common in the ovaries, endometriosis can occasionally involve the pelvic floor muscles and lead to cyst formation.
- Congenital Cysts:
- Rare cysts that develop due to developmental anomalies present from birth.

Below are potential causes or contributing factors that may lead to cyst formation in or near the pubococcygeus muscle:
