case_images: a. Findings on computed tomography.. Computed tomography showed a tense gallbladder with a heterogeneous, high-density area (arrows).. b. Findings on contrast-enhanced computed tomography in the arterial phase.. Contrast-enhanced computed tomography showed increased pericholecystic attenuation in the arterial phase (arrows), which suggests acute cholecystitis.

case_images: Computed tomography (CT) revealed a tense gallbladder with a heterogeneous, high-density area (Fig. 1a) with no evidence of pleurisy or aortic dissection. Contrast-enhanced CT showed no obvious contrast extravasation in the gallbladder or obvious mass lesions. Increased pericholecystic attenuation on arterial-phase CT was confirmed, which indicated the possibility of acute cholecystitis (Fig. 1b).
case_images: Operative findings.. Operative findings did not reveal any evidence of malignancy in the gallbladder serosa.

case_images: Congestive findings were noted from the body to the fundus of the gallbladder (Fig. 2).
case_images: Macroscopic findings of the specimen.. A papillary, infiltrating-type lesion measuring 25 x 17 mm was observed in the body of the gallbladder.

case_images: Examination of the resected specimen revealed a blood clot-filled gallbladder lumen and a gallbladder body with a papillary, infiltrating-type lesion measuring 25 x 17 mm (Fig. 3).
