The majority of hemangiomas with type-3 Lobulated contour was defined as an interface with the liver parenchyma composed by multiple small well-demarcated outpounchings.

Fig. Even so, it is often not possible to define the full cross section of the liver on the left side of the screen, and a portion of the liver will appear cut off (Fig. are common, but not especially unusual. To evaluate the occurrence rate of lobulated margination of hepatic hemangiomas. These sections shrink in the direction of the obliterated trunk, the peritoneum generally follows, the surface is affected, and fissures result, which run in various directions, and above which the healthy tissue projects in the shape of large rounded protuberances.
