Hypercalcaemic encephalopathy as a presenting manifestation of sarcoidosis.

A 66-year-old woman presented to us with features of encephalopathy with asterixis, preceded by unsteadiness of gait and behavioural abnormalities. On subsequent investigations, hypercalcaemic crisis and compromised renal function were noted. Stepwise approach to determine the cause behind hypercalcaemia with compromised renal function revealed underlying granulomatous disease (sarcoidosis). Later, development of maculopapular rash and subsequent biopsy from the lesion confirmed the diagnosis of sarcoidosis. Her clinical and biochemical parameters improved considerably on initiation of conservative pharmacological therapy.
