Case Discussion

This is a case of ovarian germ cell tumour/yolk sac tumour, a very rare but aggressive type of malignancy.

In cases of large abdomino-pelvic masses, the radiologist must try to include in the report, the origin of mass, morphological characteristics, anatomical plane extension and also if any suspicious or evident nodes/metastasis.

Closest differentials can be mentioned in  diagnostic dilemma masses.
