Thrombosed and calcified epididymal-vasal vascular structures mimicking a paratesticular mass: A case report.

Thrombosed scrotal venous structures are rare causes of scrotal pain and may mimic paratesticular tumors. We report a 53-year-old man with painful rosary-like nodularity along the right vas deferens after prior hydrocelectomy. Doppler ultrasonography showed preserved testicular perfusion and a thrombosed epididymal appearance. Surgical exploration revealed nodular changes extending from the vas deferens to the epididymis. Testis-sparing epididymectomy with excision of the involved vasal segment was performed. Histopathology showed enlarged epididymal structures with dilated thrombosed vascular channels and gross calcified foci. Pain resolved completely after surgery without testicular atrophy.
