What causes peritoneal inclusion cysts?
Peritoneal inclusion cysts occur almost exclusively in premenopausal women with a history of previous abdominal or pelvic surgery, trauma, pelvic inflammatory disease, or endometriosis [1, 5]. Peritoneal inclusion cysts tend to grow slowly as more fluid is secreted by the ovaries and not reabsorbed by the peritoneum.
What is a peritoneal inclusion cyst?
Peritoneal inclusion cysts are complex cystic adnexal masses consisting of a normal ovary entrapped in multiple fluid-filled adhesions. The cysts usually develop in women of reproductive age who have a history of previous pelvic surgery or pelvic infection.
Can a peritoneal inclusion cyst rupture?
Third, after surgical resection, the recurrence rate is 30-50%. Fourth, peritoneal inclusion cysts tend to rupture frequently just after the abdomen is opened, and resection is difficult because tissue planes are poor- ly defined.
Can a peritoneal cyst be cancerous?
Occasion- ally, cuboidal cells can undergo squamous metaplasia; however, peritoneal inclusion cysts have no malignant potential.
How do you get rid of a peritoneal cyst?
Objectives: Peritoneal inclusion cyst (PIC) is defined as a fluid-filled mesothelial-lined cysts of the pelvis and it is most frequently encountered in women of reproductive age. The treatment options are observation, hormonal management, imaging-guided aspiration, image-guided sclerotherapy and surgical excision.
How is a peritoneal cyst treated?
Can an inclusion cyst be cancerous?
Epidermal inclusion cysts are common and typically harmless, but rarely can become malignant (cancerous). Approximately 1% have been shown to transform into malignancy.
Where is peritoneal inclusion cyst located?
Multiloculated peritoneal inclusion cysts or benign cystic mesotheliomas were first described in 1928 by Plaut [1]. These cysts are most commonly found in women of reproductive years and they involve the abdomen, pelvis and retroperitoneum [2, 3].
Are peritoneal cysts painful?
Patients with peritoneal inclusion cysts (PICs) often suffer from progressive abdominal or pelvic pain. There is no established treatment.
What is the prevalence of peritoneal inclusion cysts?
Peritoneal inclusion cysts occur almost exclusively in premenopausal women with a history of previous abdominal or pelvic surgery, trauma, pelvic inflammatory disease, or endometriosis. Most patients with peritoneal inclusion cysts present with pelvic pain or a pelvic mass. About 10% are discovered incidentally.
How are cystic lesions within the peritoneum classified?
Cystic lesions within the peritoneum have been classified classically according to their lining on histology into four categories-endothelial, epithelial, mesothelial, and others (germ cell tumors, sex cord gonadal stromal tumors, cystic mesenchymal tumors, fibrous wall tumors, and infectious cystic peritoneal lesions).
Which sonogram findings are characteristic of peritoneal inclusion cysts (arrows)?
Coronal endovaginal sonogram reveals large multiloculated peritoneal inclusion cyst (arrows). One locule contains echogenic fluid (e), which was old blood. Occasionally, endometriosis is complicated by the formation of a peritoneal inclusion cyst that causes progressive and severe adhesions around the lesion.
How are lymphangiomas differentiated from primary peritoneal masses?
Clinical history and imaging features may help differentiate intra-abdominal collections from primary peritoneal masses. Lymphangiomas are benign multilocular cystic masses that can virtually occur in any location within the abdomen and insinuate between structures.
