Mature Ovarian Teratoma with Large Floating Fat Globules

Floating ball appearance in ovarian cystic teratoma.

The presence of floating fat balls or globules in an ovarian cystic teratoma is an unusual finding. Herein, we present ultrasonographic and tomographic findings of a rarely reported case of cystic teratoma with a floating fat ball.

Early diagnosis of malignant-transformed ovarian mature cystic teratoma: fat-suppressed MRI findings

The most common form of malignant transformation developing from a mature cystic teratoma is squamous cell carcinoma, representing 80% of malignant transformations, while adenocarcinoma accounts for approximately 5%. Because of this rarity, few reports exist of preoperative diagnosis of this tumor by magnetic resonance imaging, in particular with fat suppression techniques. Here, we report magn...

A floating ball: a pathognomonic sign of ovarian cystic teratoma.

A 47-year-old woman with regular menstrual cycle had no remarkable history in the past. She was diagnosed invasive ductal carcinoma of right breast and received imaging survey for cancer staging. In transabdominal ultrasonography, a 6-cm hypoechoic cystic mass with an echogenic globular nodule, 2 cm in diameter containing some hyperechoic dots, was identified in the pelvis by accident (Figure 1...

Pseudomyxoma peritonei: unusual origin from an ovarian mature cystic teratoma.

Pseudomyxoma peritonei (PMP) is classified into pathologically and prognostically distinct categories, such as disseminated peritoneal adenomucinosis (DPAM) and peritoneal mucinous carcinomatosis. There is overwhelming evidence that DPAM arises from a mucinous adenoma of the appendix. The one exception to this is the presentation of a mature ovarian cystic teratoma as PMP where the appendix is ...
