Abstract

Fibrous paratesticular pseudotumor is a rare benign condition that can mimic scrotal neoplasms and lead to unnecessary orchiectomy. We report a 21-year-old man who presented with acute right hemiscrotal pain and swelling. Ultrasound showed a solid extratesticular hyperechoic nodule in the tail of the right epididymis with preserved testicular vascularity, and pelvic magnetic resonance imaging demonstrated a circumscribed lesion that was hypointense on T2-weighted sequences, without diffusion restriction, and with post-contrast enhancement—features consistent with fibrous proliferation. Testis-sparing local excision was performed and histopathology confirmed a fibrous pseudotumor of the epididymis. A brief literature review is provided, emphasizing the role of MRI and intraoperative frozen section to avoid orchiectomy, the possible association with IgG4-related disease in a subset of patients, and the excellent prognosis after complete excision.
