Medullary sponge kidney and hyperparathyroidism.
Medullary sponge kidney (MSK), parathyroid adenoma, renal cell carcinoma, and renal-leak hypercalciuria coincided in 1 female patient. Renal-leak hypercalciuria was not corrected by removal of a parathyroid adenoma. Since the patient had renal tubular acidosis (RTA), alkali treatment was conducted and resulted in the correction of hypercalciuria. Renal cell carcinoma eventually developed and MSK was confirmed histologically. This case suggests that MSK and primary hyperparathyroidism occurred independently.
