Sonographic diagnosis of peritoneal inclusion cysts

Peritoneal inclusion cysts have not received the attention they merit in the imaging literature. We present a series of peritoneal inclusion cysts and describe their sonographic features. Our findings lead us to encourage more conservative therapies. All seven patients in our series had pelvic pain and had undergone surgery previously. An ovary surrounded by septations and fluid was the most common finding by transvaginal sonography. Dopplerexamination showed low resistive flow in the septations. Conservative therapy was used in five cases with excellent results. We found that a confident diagnosis of peritoneal inclusion cysts is possible with ultrasonography. This diagnosis should encourage the use of more conservative therapy.
