Abstract:
A 47-year-old man had elevated serum CA 19-9 after a routine health check-up. He had normal CA 19-9 levels during the preceding 8 years on annual heath checks. Imaging studies for pancreatic or biliary tract diseases revealed no abnormalities. A huge hypermetablic lesion was found in the right lobe of the thyroid on 18F-fluorodeoxyglucose positron emission tomography/computed tomography. We performed a fine needle aspiration of the thyroid nodule. He was diagnosed with papillary thyroid carcinoma and underwent a total thyroidectomy with a modified radical neck dissection. Serum CA 19-9 level decreased to the normal range after surgery. Although there have been few reports of patients with elevated serum CA 19-9 levels due to papillary thyroid carcinoma, this is the first report showing such an association in Korea. Thyroid cancer should be considered when the causes of elevated serum CA 19-9 are unclear.
