A 32-year-old male with known Behcet's disease presented to the ER with acute scrotal pain. There was no history of trauma. a On power mode Doppler US, a triangular-shaped heterogeneous hyperechoic lesion with no apparent vascularity is seen (arrows). b Coronal T2W fat-suppressed MR image shows a triangular heterogeneous hyperintense lesion (asterisk) with the apex pointing towards the testicular mediastinum and surrounded by a T2 hypointense rim. Mild reactive hydrocele is also noted. c Coronal postcontrast T1W fat-suppressed MR image demonstrates the hypoenhancing lesion (asterisk) with sharp borders and peripheral rim enhancement (arrowheads). Imaging findings were consistent with segmental testicular infarction, likely related to Behcet's disease. The patient was placed on supportive treatment, to which he responded well
