Unusual ?floating balls? appearance of an ovarian cystic teratoma: Sonographic and CT findings

Ovarian cystic teratoma with a pathognomonic appearance of multiple floating balls: a case report and investigation of common characteristics of the cases in the literature

“…In some studies (6,10,13,16,18), serological tests were done for a differential diagnosis of echinococcus, rarely found in the pelvis. We do not believe that they are necessary, because usually it is not difficult to differentiate with a careful ultrasonographic examination hyperechoic globules floating in a hypoechoic fluid from hypoechoic daughter cysts of echinococcus.…”

“…We found 18 cases of ovarian cystic teratoma with multiple floating balls from 14 studies in the review of the literature (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18). We investigated common features in these 18 cases from the literature and our present case, such as the age of the women, the size of the tumor, and the side of the body in which the tumor located.…”

Meat balls: a pathognomonic ultrasound and computed tomography finding in mature cystic teratoma

“…Ovarian teratomas have a wide spectrum of imaging appearances that may lead to diagnostic difficulty, but as demonstrated in this case and the previous cases 2–6 the presence of floating fat attenuation balls within a pelvic mass is a rare but pathognomonic appearance for benign cystic ovarian teratoma.…”

“…To our knowledge, teratomas having multiple intracystic rounded ‘floating’ spherules of similar size and composition have only been noted in nine previous cases in the literature. These lesions have been described in the ovary, 2–6 retroperitoneum 7 and the mediastinum 8 …”
