Paratesticular inflammatory pseudotumor. A 11-year-old boy who presented to ER with painless left scrotal swelling. a Gray scale US image demonstrates a heterogeneous, predominantly hypoechoic extratesticular lesion (arrowheads), adjacent to the lower pole of the left testis (asterisk).

Surgical removal of the tumor, with preservation of the left testis, instead found paratesticular inflammatory pseudotumor
