비기능성 부갑상선 낭종 1예
Parathyroid cyst are rare lesion of the neck and superior mediastinum. They are classified as either function-al or nonfunctional based on the presence or absence of hyperparathyroidism. They typically present as a palpa-ble neck mass, or as an incidental finding during neck surgery. So, it must be included within the differential diagno-sis of a neck lump. A 48-year old woman was admitted to our hospital for evaluation of left anterior neck mass. Phys-ical finding showed soft, movable, non-tender mass on the lower left third of the neck. Laboratory findings reveal-ed normal thyroid function and normal serum calcium level. On previous history, patient underwent two times sono-guided fine needle aspiration at local clinic, and about 10cc clear watery aspirate was noted. Computerized to-mography findings showed non-enhancing hypodense cystic lesion on left thyroid area with tracheal deviation to right side. Preoperative diagnosis was thyroid cyst, and thyroidectomy was planed. Intra-operative finding sho-wed huge cystic mass occupying the left thyroid area and smooth, shiny, semitransparent thin cyst wall was noted, which was loosely attached to the thyroid. The cyst was easily dissected free from the thyroid and surrounding tissues. After cyst removal, pathological study confirmed as a parathyroid cyst.
