Peritoneal inclusion cysts, also known as inclusion cysts of the peritoneum or benign cystic mesotheliomas, are a type of benign cyst that forms within the peritoneum, the thin layer of tissue that lines the inner wall of the abdomen and covers most of the abdominal organs. These cysts are typically associated with the presence of adhesions, inflammation, or surgical scars within the abdominal cavity, which can trap peritoneal fluid and lead to cyst formation.

Causes and Risk Factors

Peritoneal inclusion cysts are thought to arise from the entrapment of peritoneal fluid due to adhesions, inflammation, or the presence of foreign bodies within the abdominal cavity. Women are more commonly affected than men, particularly those with a history of pelvic inflammatory disease, endometriosis, surgery in the pelvic area, or trauma to the abdomen. These conditions can lead to the formation of scar tissue, which in turn can trap peritoneal fluid and create a cyst.

Symptoms

Many individuals with peritoneal inclusion cysts do not experience symptoms and the cysts are often discovered incidentally during imaging tests for other conditions. When symptoms do occur, they may include:

• Abdominal or pelvic pain
• A feeling of fullness or pressure in the abdomen
• Increased abdominal girth
• Pain during intercourse

Diagnosis

The diagnosis of peritoneal inclusion cysts typically involves imaging studies such as ultrasound, computed tomography (CT) scan, or magnetic resonance imaging (MRI). These imaging techniques can help to distinguish peritoneal inclusion cysts from other types of cysts or masses in the abdomen. In some cases, a laparoscopy may be performed to obtain a definitive diagnosis and, if necessary, to remove the cyst.

Treatment

Treatment for peritoneal inclusion cysts depends on the size of the cyst and the severity of symptoms. Small, asymptomatic cysts may not require treatment and can be monitored for changes over time. For symptomatic cysts, treatment options may include:

• Hormonal therapy to reduce the production of peritoneal fluid
• Pain management strategies
• Surgical removal of the cyst, which may be performed laparoscopically

Prognosis

The prognosis for individuals with peritoneal inclusion cysts is generally good, especially when the cysts are small and asymptomatic. However, there is a risk of recurrence, particularly if the underlying conditions that led to the formation of the cyst, such as adhesions or endometriosis, are not addressed.

Prevention

Preventing the formation of peritoneal inclusion cysts involves managing the underlying conditions that contribute to their development. This may include treating infections promptly, managing endometriosis, and using caution to minimize tissue damage during abdominal surgeries.
