[A case of perineal abscess due to urethral fistula in a patient with spinal cord injury].

We report a case of perineal subcutaneous abscess due to urethral fistula in a patient with spinal cord injury. A 39-year-old male visited our hospital complaining of left scrotal swelling and fever. The left scrotum and perineal skin were swollen to the size of a goose egg, and pus was discharged from the perineal swollen bump. Magnetic resonance imaging (MRI) suggested an urethral fistula with a large subcutaneous abscess. The abscess was resected with debridement of necrotic tissue, and a cystostomy was placed. Endoscopy revealed a fistula in the bulbar urethra. The characteristics of this rare entity are discussed.
