Testicular hematoma. A 30-year-old male presenting after a fall from height for which he did not seek any medical care. Ten days after the initial event, he presented with a palpable left testicular mass. a Gray scale US shows a heterogeneous hypoechoic lesion in the left testis (arrowheads). b There was mild internal vascularity within this lesion on color Doppler US exam. Hematoma was considered as the initial diagnosis but as testicular tumor could not be ruled out an MRI order was placed. c-d Axial plane T2W fat-suppressed and T1W images show high T1 and T2 signal intensities within the central part of the lesion (arrows) which was thought to represent hemorrhage in subacute phase. The peripheral low T2 signal intensity was considered hemosiderin deposition. e Axial plane postcontrast MR image shows no internal enhancement within the central part (arrow). During the follow-up, the lesion completely regressed, leaving mild testicular atrophy (not shown)
