BACKGROUND: A 40-year-old man presented to a hospital emergency department with acute-onset, bilateral, painless swelling of the scrotum, which had developed progressively over the previous 12 h. He was physically well with no remarkable medical history, and was not taking any medication. He had no history of allergies or trauma (including insect bites to the genitalia), no urinary symptoms, and was not sexually active. INVESTIGATIONS: Physical examination, assessment of erythrocyte sedimentation rate, white blood cell count, renal function panel, urine microscopic analysis, urine cultures, transillumination, and scrotal ultrasonography. DIAGNOSIS: Acute idiopathic scrotal edema. MANAGEMENT: The patient received expectant management and treatment with an NSAID to relieve his inflammation. He was discharged from hospital and his symptoms resolved within 72 h of onset of treatment.
