Right hepatectomy for giant cavernous hemangioma with diffuse hemangiomatosis around Glisson’s capsule

Figure 1 There was contrast enhancement at the periphery of the mass consistent with a cavernous hemangioma.

Figure 2 High intensity on T2-weighted magnetic resonance imaging (A) and high intensity on diffusion magnetic resonance imaging (B).

Figure 3 Resected tumor was 200 mm × 140 mm × 85 mm in size and 910 g in weight.

Figure 4 Cut section of the resected tumor. The white area has tumor degeneration and loss of tumor cells.

Figure 5 Histological findings of a giant tumor reveal endothelial cell proliferation and dilated blood channels (hematoxylin and eosin staining, × 4).

Figure 6 Hemangiomatous lesions (arrows) were scattered around the Glisson’s capsule (star) on the back ground liver (hematoxylin and eosin staining, × 1. 25).
