It is difficult to distinguish ovarian germ cell tumors on CT alone, however, pelvic/abdominal CT scan may be helpful in the diagnosis. Sensitive findings on CT scan for the diagnosis of mature teratoma include Fat attenuation, presence or absence of calcification in the cyst wall, palm-tree like protrusion, and fat-fluid levels. Presence of cauliflower appearance with irregular borders may warrant the necessity to search for malignant transformation of these tumors. CT scan findings characteristics of immature teratoma include A large, irregular solid mass, presence of coarse calcification, small foci of fat, and Hemorrhage. CT findings associated with other ovarian germ cell tumors are not specific, but may be helpful.
