title: An unusual cause of abdominal pain: thiazide-related hypercalcemia in a patient with veiled hyperparathyroidism and thyroid papillary carcinoma.
abstract: Hypercalcemia is an uncommon cause of abdominal pain and may be overlooked in the Emergency Department. In this case report, we describe the case of a 48-year-old woman with a prior history of urolithiasis who presented to the Emergency Department with diffuse abdominal pain. She had taken Trichlormethiazide 1 mg daily for her urolithiasis. She was diagnosed with thiazide-related hypercalcemia; hyperparathyroidism and thyroid papillary carcinoma were unveiled during her hospitalization. A thorough history and complete physical examination, paired with appropriate but judicious diagnostic testing, are essential to detecting these unusual causes of abdominal pain.
