  Fig. 1. Abdomen computed tomography (CT) findings. (A) Enhanced CT showed focal enhancement and wall thickening on the fundus (yellow arrow) of the gallbladder without disruption of the wall layer. (B) A follow-up CT showed similar findings, but with enlarged enhancing wall thickening and a hypodense lesion on the gallbladder fundus (yellow arrow). Direct liver invasion or wall disruption of the gallbladder was not definitive.

  Fig. 2. Endoscopic ultrasound image shows about 2×1 cm sized elliptical wall thickening without disruption of the wall layer. Internal echogenicity was mixed with diffuse hyperechoic spots and hypoechoic lesions.

  Fig. 3. Pathologic features of the resected specimen. (A) A Low-power field (hematoxylin and eosin stain, ×10) showed Rokitansky-Aschoff sinuses resulting from hyperplasia and herniation of epithelial cells through the fibromuscular layer of the gallbladder wall. (B) A high-power field (hematoxylin and eosin stain, ×100) revealed abundant infiltration of foamy histiocytes, lymphocytes, and multinucleated giant cells.
