case_images: a Abdominal computed tomography (CT) revealed a low-density mass in the gallbladder. b Abdominal contrast-enhanced CT showed a slightly enhanced region of the tumor in the gallbladder (arrow).

case_images: A computed tomography (CT) scan of his abdomen revealed a mass in the gallbladder (Fig. 1a). The contrast-enhanced CT scan revealed a slightly enhanced region in a low-density area of the gallbladder (Fig. 1b).
case_images: Magnetic resonance imaging on T2- (a) and diffusion-weighted images (b) showed a high-intensity area in the tumor (arrow).

case_images: MRI revealed a high-intensity region on T2- and diffusion-weighted images (Fig. 2a, b). Moreover, ultrasonography was performed, but the calcification of the gallbladder wall did not allow taking a clear view.
case_images: The resected specimen consisted of a 10-cm solid tumor with hematoma (arrow).

case_images: In the resected specimen, the gallbladder was filled with a solid tumor and hematoma, which measured 10.0 x 8.0 x 5.5 cm (Fig. 3).
case_images: Hematoxylin and eosin stain (x200 magnification) showed aggregated vessel components (a). CD31 (b) and CD34 (c) staining showed the presence of vessel components.
