Intratesticular arteriovenous malformation: A rare benign testicular lesion in an adolescent male

Abstract

We present the clinical course and imaging findings of an intratesticular arteriovenous malformation found in an adolescent patient.The patient presented for evaluation of a possible testicular mass. Evaluation included grayscale and Doppler ultrasound that demonstrated a vascular mass. Serum tumor markers were unremarkable. Magnetic resonance imaging was used to make the diagnosis of intratesticular arteriovenous malformation.Intratesticular arteriovenous malformations are exceedingly rare, with only four other cases noted on literature review. This case presents unique findings including testicular microlithiasis and a history of cryptorchidism. The case was managed conservatively with ultrasound surveillance at six months.
