Abstract
We report a case of Fournier's syndrome which formed a periproctal abscess widely spreading to the supraumbilical abdominal wall. A 30-year-old man was seen at the hospital because of high fever and periproctal pain. He had an underlying disease of diabetes mellitus and spent seven days after the symptom appeared. An incisional drainage was performed, but inflammatory changes progressed. Computed tomography (CT) and ultrasonography (US) revealed a wide abscess cavity spreading to the scrotum and supraumbilical abdominal wall. A wide drainage made a remission. In the treatment of periproctal abscess, the evaluation of the abscess cavity with CT and US is essential for early sufficient drainage, by entertaining a possible existence of Fournier's syndrome which can rapidly and progressively spread.
