We present the case history of a patient with bilateral calf swelling that was initially managed as deep vein thrombosis but was later found to be due to rhabdomyolysis. The initial management may have contributed to the development of acute renal failure and the need for dialysis.

* Rhabdomyolysis should be considered in the differential diagnosis of swollen legs. Mismanagement as deep vein thrombosis may lead to acute renal failure

Case report

A 44 year old man who had previously been well, apart from frequently misusing alcohol, was admitted to a neighbouring hospital's accident and emergency department after a particularly heavy bout of drinking, which had left him in a stuporous state. When he eventually woke up he could not walk; he had “pins and needles” in his legs, and his calves were swollen. Bilateral deep vein thrombosis was diagnosed and apparently confirmed by non-filling of deep veins …
