Undiagnosed scrotal swelling in a 36-year-old man: A congenital arteriovenous malformation.

We have reported the case of a 36-year-old man with severe scrotal swelling that had remained undiagnosed after multiple diagnostic tests. The patient had presented with scrotal swelling, multiple weeping ulcers on the dorsal aspect of the scrotum, and worsening pain affecting his day-to-day functioning. Duplex ultrasound showed low- to no-flow hypervascularity and dependent edema suspicious for a vascular malformation. Treatment included sequential Gelfoam (Pfizer, New York, NY) embolization using ultrasound-guided direct cannulation and traditional angiography. The scrotal circumference decreased by 65%, with moderate relief of his pain. The details from the present case have highlighted the significance of vascular malformations, various diagnostic and therapeutic techniques used, and value of endovascular embolization.
