Figure 8d. Hepatic cavernous hemangioma. (a) Axial T2-weighted MR image shows a high-signal-intensity lobulated tumor with central necrosis (*). (b) Axial contrast-enhanced T1-weighted MR image shows the tumor with the typical centripetal pattern of peripheral enhancement (arrows). (c) Photograph of the gross specimen shows the vascular cystic spaces (arrows) of the tumor (hemangioma). (d) Photomicrograph (original magnification, x200; H-E stain) shows dilated vascular spaces filled with blood and lined by a single layer of endothelial cells (arrows).
