A computed tomography of her abdomen revealed a 6.2 x 5.9 x 4.1-centimeter exophytic lesion arising from the posteroinferior aspect of the right liver lobe with a small amount of fluid tracking inferior to the lesion into the right parapelvic gutter suggestive of hemorrhage (Figures 1, 2, 3, and 4).
Contrast-enhanced computed tomography of the abdomen in the coronal plane demonstrates intralesional areas of arterial enhancement (arrow). There is a small amount of paracolic gutter fluid.

A computed tomography of her abdomen revealed a 6.2 x 5.9 x 4.1-centimeter exophytic lesion arising from the posteroinferior aspect of the right liver lobe with a small amount of fluid tracking inferior to the lesion into the right parapelvic gutter suggestive of hemorrhage (Figures 1, 2, 3, and 4).
Reimaging of the abdomen with computed tomography three days subsequent to the original study demonstrates further increase in size of the ruptured hemangioma, and it now measures 61.5 mm.

A computed tomography of her abdomen revealed a 6.2 x 5.9 x 4.1-centimeter exophytic lesion arising from the posteroinferior aspect of the right liver lobe with a small amount of fluid tracking inferior to the lesion into the right parapelvic gutter suggestive of hemorrhage (Figures 1, 2, 3, and 4).
Reimaging of the abdomen with computed tomography three days subsequent to the original study in the coronal plane exhibits an increase in the amount of paracolic gutter fluid (arrowheads), and the craniocaudal dimension of the hemangioma is now 73.8 mm.

A computed tomography of her abdomen revealed a 6.2 x 5.9 x 4.1-centimeter exophytic lesion arising from the posteroinferior aspect of the right liver lobe with a small amount of fluid tracking inferior to the lesion into the right parapelvic gutter suggestive of hemorrhage (Figures 1, 2, 3, and 4).
(a) Liver parenchyma with adjacent nonencapsulated mass (H&E, 20x), (b) tumor with a proliferation of thickened blood vessels with myxoid changes (H&E, 400x), (c) the hemangioma shows areas of hyalinized fibrosis (H&E, 400x), and (d) areas of loose connective tissue within the tumor (H&E, 400x).

The tumor showed extensive areas of dense and loose fibrous tissue made of collagen and elastic fibers, degenerative changes, and hyalinization findings diagnostic of sclerosing (ancient) hemangioma (Figure 5).
