The iliococcygeus muscle is one of the muscles that make up the pelvic floor, playing an important role in supporting pelvic organs and maintaining continence. Sometimes, cysts can form in or around this muscle. These are known as iliococcygeus muscle cysts. In this guide, we explore what these cysts are, how they form, and what they mean for your health.
Iliococcygeus muscle cysts refer to fluid-filled sacs that develop in or adjacent to the iliococcygeus portion of the pelvic floor muscles. These cysts can vary in size and may be caused by different factors such as infection, trauma, or developmental issues. They can sometimes cause discomfort or affect pelvic functions.
Pathophysiology
Understanding the basic anatomy and function of the iliococcygeus muscle is crucial for grasping how cysts may develop.
Structure of the Iliococcygeus Muscle
-
Location:
The iliococcygeus is part of the pelvic floor muscles, extending from the inner surface of the pelvic bone (ischial spine and arcus tendineus) to the coccyx (tailbone). It forms a supportive sling for pelvic organs. -
Shape and Composition:
This muscle is thin, flat, and fan-shaped. It works together with other pelvic floor muscles to provide stability and support.
Blood Supply
-
Main Blood Vessels:
The blood supply to the iliococcygeus muscle comes primarily from small branches of the internal iliac artery. Adequate blood flow is essential for the muscle’s health and repair processes. -
Importance of Vascular Supply:
Good blood circulation helps deliver oxygen and nutrients, which are necessary for healing if a cyst or injury occurs.
Nerve Supply
-
Nerves Involved:
The iliococcygeus muscle is innervated by branches of the pudendal nerve and nerves from the sacral plexus. This nerve supply enables muscle contractions and also relays pain signals if there is inflammation or injury. -
Role in Sensation:
If a cyst irritates the nearby nerve fibers, it may cause pain, discomfort, or altered sensation in the pelvic area.
Functions of the Iliococcygeus Muscle
-
Pelvic Support:
This muscle is critical for supporting pelvic organs such as the bladder, uterus (in females), and rectum. -
Continence:
By contracting and relaxing, the iliococcygeus helps control urinary and fecal continence. -
Posture and Stability:
It contributes to the stability of the pelvis and lower back. -
Childbirth:
In women, the pelvic floor muscles play a significant role during labor and delivery.
Types of Iliococcygeus Muscle Cysts
Cysts in the iliococcygeus area can vary in nature and appearance. Common types include:
- Simple Fluid-Filled Cysts:
- Typically benign and contain clear fluid.
- Complex Cysts:
- May have internal septations (walls) or debris. They sometimes require more detailed imaging to assess.
- Infectious or Inflammatory Cysts:
- Resulting from an infection or inflammation of the pelvic tissues.
- Developmental (Congenital) Cysts:
- Formed during fetal development and may be discovered later in life.
- Post-Traumatic Cysts:
- Occur following pelvic trauma or injury that leads to cyst formation.
- Iatrogenic Cysts:
- Rarely, cysts can develop following pelvic surgeries or procedures.
Causes of Iliococcygeus Muscle Cysts
Cysts can develop due to various factors. Here are 20 potential causes:
- Pelvic Trauma:
- Injury from accidents or falls.
- Surgical Complications:
- Formation of cysts following pelvic or gynecological surgeries.
- Infections:
- Pelvic infections can lead to abscess formation that later becomes cystic.
- Inflammatory Conditions:
- Chronic inflammation may result in cyst formation.
- Congenital Abnormalities:
- Developmental defects present from birth.
- Endometriosis:
- In women, misplaced endometrial tissue can cause cysts in pelvic muscles.

- Nerve Damage:
- Altered nerve signals may affect muscle function and contribute to cyst development.
- Autoimmune Disorders:
- Conditions that cause chronic inflammation may lead to cyst formation.
- Radiation Therapy:
- Pelvic radiation can cause tissue changes and cysts.
- Foreign Body Reaction:
- Reaction to implanted devices or materials.
