Fibrous pseudotumor in a 61-year-old man. (a)Longitudinal US image shows a solid mass (arrow) adjacent to the testis (TEST) and epididymis (EPI). The mass is hypoechoic compared with the testis and demonstrates faint posterior shadowing. (b)Coronal T2-weighted fat-suppressed image shows a markedly hypointense mass (arrow) with a pedunculated attachment to the tunica. It is surrounded by a high-signal-intensity hydrocele. The mass was isointense relative to the testis on a T1-weighted image (not shown). T = testis. (c) Photograph of the gross specimen shows a rubbery, slightly laminated mass. Scale is in centimeters.
