Abstract
We experienced a case of primary hyperparathyroidism which presented chief complaint of epigastralgia as a general digestive symptom and hypercalcemic crisis in the course of treatment. In spite of absence of typical bone lesion, or nephrolith, the case presented renal failure in a short period of time. Although abnormal high PTH value was observed, no other endocrine abnormalities were noted. Transfusion and administration of calcitonin made diverse clinical symptoms disappear. Image examination by scintigraphy in addition to ultrasound and computed tomography confirmed an ectopic parathyroid tumor. Radical operation was performed; a giant adenoma having cystoma inside was extirpated.
