RADIOLOGY: GASTROINTESTINAL: GI: Case# 33976: APPENDICITIS. 20 year old woman with right lower abdominal pain. She reports a history of endometriosis diagnosed by laparoscopy as well as history of previous physiologic cysts of the ovary. 1) Two cystic masses versus a solitary cystic mass with internal septation in the right ovary. The larger component has diffuse fine internal echoes. This lesion(s) is most consistent with endometrioma. Also a diagnostic possibility is a physiologic cyst with internal hemorrhage. Would suggest correlating with clinical history and following clinically to assure resolution. 2) No sonographic evidence of appendicitis.
