Rhabdomyolysis following accidental intra-arterial injection of local anesthetic.

Drug-induced myopathy, also named Nicolau syndrome, is a well-known phenomenon following intramuscular injection of certain agents, most commonly reported with penicillin or diclofenac. The mechanism responsible for the pathology is proposed to be incidental administration of the drug into the small arterioles. In this report, we present a Nicolau syndrome-like case that developed following accidental injection of a local anesthetic agent into the femoral artery during coronary angiography.
