[A case of sarcoidosis with hypercalcemia, urolithiasis, nephrocalcinosis and renal insufficiency].
A sixty nine-year-old woman was admitted to the hospital because of further examination of hypercalcemia. On July 1990, she complained of general fatigue and loss of appetite. She was pointed out to have hypercalcemia (15.1mg/dl), urolithiasis, and renal insufficiency. CT films of the chest showed swelling of the mediastinal lymphnodes and CT of the abdomen nephrocalcinosis. Ga-scintigraphy demonstrated an abnormal accumulation of gallium in the mediastinum. Levels of the parathyroid hormone was normal. Levels of the serum calcium (13.7mg/dl), angiotensin converting enzyme (30.4IU/L) and 1.25 (OH)2D (87PG/ml) were elevated. Giant cells were found in the biopsy specimen of the lung. A significant relationship between the serum calcium and creatinine were observed (r = 0.76, p < 0.02). Proximal fractional reabsorption of sodium showed to be suppressed (47.7%), and distal fractional reabsorption of sodium showed to be normal (88.4%). From these findings hypercalcemia and urolithiasis was suggested to result from sarcoidosis. The hypercalcemia and renal insufficiency improved with corticosteroid therapy.
