[Sarcoidosis with hypercalcemia, urolithiasis, renal insufficiency, and heart failure].
A 65-year-old man was admitted to our hospital because of thirstyness and left lower abdominal pain. On admission, he was found to have urolithiasis, renal insufficiency (BUN: 73 mg/dl, Crt: 4.4 mg/dl), and hypercalcemia (13.2 mg/dl). Chest X-ray films and computed tomograms showed enlargement and calcification of the hilar lymph nodes, and thickened interlobar fissures in both lungs. Levels of angiotensin converting enzyme (30.2 IU/l) and 1.25 (OH)2VitD3 (66.4 pg/ml) were elevated. Histologic examination of the specimen obtained from transbronchial lung biopsy showed non-caseous epithelioid cell granulomas. Because the level of parathyroid hormone was normal and no malignancies were detected, a diagnosis of sarcoidosis was made. Treatment with extracorporeal shock wave lithotripsy, transurethral lithotomy, saline infusion, and prednisolone (30 mg/day) alleviated the urolithiasis, renal insufficiency, and hypercalcemia. After discharge, the patient was followed up and given prednisolone therapy. About 1 month after the prednisolone dose had been tapered to 15 mg/day, the patient experienced dyspnea and facial and pedal edema. Because congestive heart failure was diagnosed, he was re-admitted to our hospital for a second time. Although he was then placed on intensive therapy, he died of ventricular tachycardia associated with sarcoidosis of the heart.
