title: [Epididymal leiomyoma: a case report].
abstract: A 30-year-old male, who underwent orchiopexy of left undescending testis in his childhood, presented with right hemiscrotal swelling without pain. Ultrasonography revealed a paratesticular tumor which showed enhancement on magnetic resonance imaging (MRI). Diffusion-weighted MRI showed decreased diffusion in the tumor, and malignant tumor could not be ruled out. High inguinal orchiectomy was carried out and pathological diagnosis was benign leiomyoma of the epididymis.
