Abstract
Guillain-Barre syndrome (GBS) is a heterogenous group of peripheral-nerve disorders with similar clinical presentation characterized by acute, self-limited, progressive, bilateral and relatively symmetric ascending flaccid paralysis, which peaks in 2-4 weeks and then subsides. The usual complications, which occur in a patient of GBS are pneumonia, sepsis, pulmonary embolism, respiratory insufficiency and cardiac arrest. The clinical course of GBS complicated by acute rhabdomyolysis is extremely rare. We present the case of GBS with marked elevation in serum creatine kinase, serum myoglobin levels and persistent hyperkalemia as a result of associated acute rhabdomyolysis.
