Calcific constrictive pericarditis with refractory hypokalemia in a patient with Gitelman's syndrome.

Calcific constrictive pericarditis can be idiopathic or associated with radiation therapy, surgery, infection, or autoimmune disorders. Gitelman's syndrome is a distal renal tubular defect involving the thiazide-sensitive luminal sodium chloride cotransporter and has been associated with nephrolithiasis and chondrocalcinosis. There has not been any case of calcific constrictive pericarditis reported so far in association with Gitelman's syndrome. We have reported a male patient with persistent hypokalemia and refractory ascites diagnosed with calcific constrictive pericarditis and Gitelman's syndrome.
