Fulminating nonclostridial gas-forming infection: a case of necrotizing fasciitis.
Perianal infection in a 40-year-old man resulted in extensive necrotizing fasciitis of the retroperitoneal space and septic shock. Despite the fact that radiography revealed linear streaking in the belly of the psoas muscle due to gas formation, the nature of the infection was necrotizing fasciitis and not myonecrosis. This contradicts Brightmore's contention that such a finding always indicates clostridial myonecrosis. Despite the absence of Clostridium welchii, necrotizing fascitis is none the less extremely serious, usually occurring in the limbs or abdominal wall superficial to muscle layers. The case reported is unusual in that infection affected the fascia deep to abdominal muscles in the retroperitoneal space, where surgical exposure is difficult. An appropriate surgical approach afforded adequate treatment.
