Epithelial cyst of the gallbladder demonstrated by ultrasonography: case report.
We present a rare case of epithelial cyst of the gallbladder in a 71-year-old man. Abdominal ultrasonography revealed a small cystic structure adjacent to the gallbladder. The cyst wall was thin and smooth, and protruded into the lumen of the gallbladder. Histologically, the cyst had no communication with the lumen of the gallbladder. The cyst wall was composed of fibro-muscular fiber, and lined by a single layer of ciliated columnar epithelium. Epithelial cyst of the gallbladder should be included in the differential diagnosis when radiological studies show a cystic structure in or adjacent to the gallbladder.
