Peritoneal inclusion cysts: ovarian fluid in peritoneal adhesions

In four women pelvic peritoneal inclusion cysts were diagnosed with ultrasound or computed tomography. Three patients had a history of multiple surgical procedures, whereas the fourth had prior severe abdominal trauma. Imaging studies showed large cystic structures contiguous with the adnexa. The normal ovarian appearance was distorted in two women. Pathologic confirmation was obtained in all cases. When large adnexal cystic structures are identified in young women with a history of surgery or trauma, the diagnosis of peritoneal inclusion cysts should be entertained. Recognition should result in conservative therapy rather than salpingo-oophorectomy.
