A Case of Pancreatitis Associated with Hyperfunctioning Intrathyroidal Parathyroid Adenoma / 대한이비인후과학회지

ABSTRACT

Both intrathyroidal parathyroid adenoma and acute pancreatitis from hyperparathyroidism are rare disorders. We report a case of acute pancreatitis from hyperfunctioning intrathyroidal parathyroid adenoma in a 40-year-old man with severe abdominal pain. Serum chemistry values show-ed high amylase, lipase, calcium and intact parathyroid hormone level, and abdominal CT revealed acute pancreatitis. A 7 mm lesion was detected inside the left upper pole of thyroid on neck ultrasonography and confirmed to be a parathyroid lesion based on fine needle aspiration cytology. After exploratory parathyroidectomy, symptoms subsided. In patients who present with acute pancreatitis, hyperparathyroidism should also be considered if risk factors such as alcohol ingestion, gallstone, previous endoscopic retrograde cholangiopancreatography, and abdominal trauma do not exist. Exploratory parathyroidectomy should be performed in a case of acute pancreatitis from primary hyperparathyroidism.
