Case contributed by Dr Ian Bickle


Follow up. Previous gynecological surgery for immature ovarian teratoma.

Patient Data

Age: 25 years old
Gender: Female

Multiple heterogenous lesions with fluid, fat and calcific elements in the liver, the largest occupying most of the right lobe and compressing the right kidney.

Numerous identical nodules/masses in the peritoneal cavity, the largest measuring 4cm in the left paracolic gutter.

Right ureteric stent.

Case Discussion

Immature ovarian teratoma is an uncommon ovarian germ cell tumor, which differs from the far more common mature ovarian teratomas (dermoid cysts). Histologically they contain immature tissue, and clinically are more malignant in behavior. It is a tumor largely of young females, as in this example.

Immature teratomas may metastasize to peritoneum, liver or lung. Large volume liver and peritoneal metastases in this case shown the soft tissue-fat-calcification typical of a dermoid.
