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).
Magnetic resonance imaging on T2- (a) and diffusion-weighted images (b) showed a high-intensity area in the tumor (arrow).

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.
The resected specimen consisted of a 10-cm solid tumor with hematoma (arrow).

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).
Hematoxylin and eosin stain (x200 magnification) showed aggregated vessel components (a). CD31 (b) and CD34 (c) staining showed the presence of vessel components.

Microscopically, the tumor comprised dilated and closely aggregated vessel components (Fig. 4a). Moreover, CD31 and CD34 staining revealed the presence of vessel components (Fig. 4b, c).
