Coronal (A) CT section shows: Right testis is normal in size and position (right arrow). A relatively well defined heterogenous soft tissue density structure of size 3 × 2 cm is noted in the peritoneal cavity (left arrow), in the infraumbilical region, to the left of midline, superior to the urinary bladder. Multiple calcific foci were noted within—The soft tissue density structure most probably represents the left atrophic undescended testis. Large complex cystic lesion (star) with multiple focal enhancing soft tissue densities arising from the left undescended testis-s/o malignant etiology. B, C Axial contrast enhanced CT sections show a large well defined cystic lesion of size 8.5 × 7.4 cm is noted arising from the undescended testis. Multiple focal enhancing soft tissue densities noted in the inner aspect of the cyst wall. Multiple calcific specks noted in the posterior aspect of cyst wall. This is suggestive of malignancy
