Case 91
Clinical Presentation
A 26-year-old man with infertility.

(A) Postcontrast axial computed tomography (CT) image obtained at the level of the inguinal canals shows bilateral, symmetric small nodules (arrows) in the inguinal canals. No bowel is seen. No evidence of hernia is identified. The nodules have uniform soft-tissue attenuation. (B) Postcontrast axial CT image obtained at a level below that of Figure A shows that the scrotum (arrows) is empty.
