우측 갑상선결절로 오인된 젠커게실 1례

초록

Zenker’s diverticulum, a pulsion diverticulum of the hypopharynx, is a rare lesion that commonly occurs in left side of hypopharynx. The incidence of esophageal diverticula is much lower than that of focal lesions or nodules of thyroid. In an ultrasonography, the outpouching just like a focal thyroid lesion, may present as an oval or circular structure. The food remnants or gas bubbles present in the diverticulum may mimic microcalcifications presented in papillary thyroid carcinoma. We reported a case of right side Zenker’s diverticulum mimicking a thyroid cancer in thyroid ultrasonography.
