Malignant syndrome is a rare complication occurring during the course of drug treatment for Parkinson's disease. It resembles neuroleptic malignant syndrome and is characterized by fever, marked rigidity, altered consciousness, leucocytosis and elevated creatine kinase. Malignant syndrome is a potentially fatal condition and awareness of this condition is imperative for prevention and treatment. The commonest precipitating factor is dopaminergic drug withdrawal or dose reduction. We report malignant syndrome (precipitated by hyponatremia) in a case of Parkinson's disease, in the absence of dopaminergic drug withdrawal. A 60-year-old man presented with fever, severe rigidity and altered sensorium following repeated vomiting. On investigation, he was found to have hyponatremia precipitated malignant syndrome. Treatment with hydration, cooling, correction of hyponatremia and dopaminergic drugs reversed his condition. The triad of fever, severe rigidity and altered sensorium should prompt evaluation for malignant syndrome in Parkinson's disease.
