Revealed yolk sac tumour, predominantly exhibiting a polyvesicular vitelline pattern. In addition, endometroid like and reticular patterns also seen.
This is a case of ovarian germ cell tumor/yolk sac tumor, 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.
