Abstract
Gas gangrene in the neck region is very rare. A case of gas gangrene spreading in the neck is reported. A 59-year-old man having a history of diabetes mellitus and chronic hepatitis was admitted to our hospital because of pharyngalgia. He was treated with antibiotics. But he had severe swelling of the neck and a high fever after four days. By x-p and CT, some free air was found in the neck. He was diagnosed as having gas gangrene and had emergency complementary surgical drainage and debridement under general anesthesia. The postoperative course was good without any complications. To diagnose gas gangrene, CT is very valuable. Complementary surgical drainage and debridement are necessary for treatment of gas gangrene.
