Carbon monoxide poisoning with severe myonecrosis and acute renal failure.

A case of carbon monoxide (CO) poisoning with severe myonecrosis and acute renal failure (ARF) is presented with extremely high values of CPK but with preservation of myocardial tissue. A discussion of the broad effects of CO intoxication is undertaken with a review of the pertinent literature. Diagnostic and therapeutic mainstays are presented with some pitfalls and alternatives to their implementation. Computed tomography of affected muscles is presented as an alternative to muscle biopsy, and a unique modality of noninvasive diagnosis of myonecrosis.
