Sarcoidosis with Hypercalcemia — Successful Treatment of Renal Insufficiency and Renal Calcification with Prednisolone —

Abstract

A case of muscular sarcoidosis accompanied by severe hypercalcemia (serum calcium 15.5 mg/ dl), renal insufficiency and renal calcification is reported. Sarcoid granulomas were found in the biopsy specimens of the lung and the muscle. The administration of prednisolone effectively improved not only muscle weakness but also hypercalcemia, renal insufficiency and renal calcification. This is a rare case of sarcoidosis in which renal calcification remitted after treatment with prednisolone. It is thus suggested that prednisolone treatment should be considered not only for hypercalcemia, but also for renal insufficiency caused by renal calcification in patients with sarcoidosis. © 1994, The Japanese Society of Internal Medicine.
