History of giant left hepatic lobe hemangioma. ABDOMEN:LIVER, BILIARY TRACT: Mildly prominent liver measuring up to 19.6 cm in the craniocaudal dimension likely in part due to a normal variant Reidel lobe. The left lobe extends into the left upper quadrant.There are numerous bilobar liver lesions.The largest is a complex left hepatic lobe partially exophytic mass which is hyperintense on T2-weighted imaging with numerous internal septations, measuring 12.1 x 8.1 cm (series 401/28), unchanged. This lesion demonstrates peripheral nodular discontinuous contrast pooling which progresses centrally on delayed imaging compatible with a giant hemangioma.Multiple additional smaller lesions with similar imaging characteristics are noted in both lobes of the liver.Segment 6 T2-weighted mildly hypointense in T1-weighted hypointense lesion demonstrating homogeneous arterial phase enhancement, lobular contour, and isointensity on delayed imaging, compatible with a focal nodular hyperplasia, unchanged in size measuring 3.4 x 3.0 cm (series 1 102/217).SPLEEN: Previously seen splenic focus may have been perfusional.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Previously seen ill-defined heterogeneous enhancement at the level of the right lower rib cage is not evident on today's study.OTHER: No significant abnormality noted.
1.Stable left hepatic lobe giant hemangioma with additional smaller bilobar hemangiomata.2.Segment VI peripheral lesion with imaging findings consistent with focal nodular hyperplasia, unchanged.
