Peritoneal inclusion cysts as a diagnostic and treatment challenge.

Peritoneal inclusion cysts (PICs) are benign multilocular cysts that consist of fluid localized between intraperitoneal adhesions. They usually present in women in the third and fourth decades of life with a history of prior pelvic or abdominal surgery, especially months to 20 years ago. PICs have low mortality and the potential for high morbidity.
