Primary hyperparathyroidism presenting with acute pancreatitis and asymptomatic bone involvement.

A 15-year-old female patient presented to the emergency room with vomiting and abdominal pain. She had two similar attacks in the previous three months both of them were diagnosed as pancreatitis in two different hospitals. On admission, her serum calcium and parathyroid hormone levels were very high. CT scan revealed left inferior parathyroid adenoma. Investigations to rule out possible multiple endocrine neoplasia were all negative. The patient was managed by intravenous fluids and furosemide to lower her serum calcium level. Then, left inferior parathyroidectomy was done. Postoperatively, the patient had hungry bone syndrome with severe hypocalcaemia and was managed by intravenous calcium infusion for five days in the intensive care unit. Later, she was kept on oral calcium and vitamin D supplementation. She became symptom-free and her serum calcium improved gradually.
