Management and outcome of hepatocellular adenoma with massive bleeding at presentation

Figure 1 Representative case of grade II bleeding hepatocellular adenoma involving a 23-year-old female who presented at the emergency department with an acute hematoma in the right liver lobe. A: Computed tomography without intravenous contrast shows a hyperdense fluid collection in the liver (triangle); B: Some months later after conservative treatment, the collection appeared hyperintense on T2-weighting, with a hemosiderin ring surrounding the collection (arrow); C: At the same time, the collection appeared hyperintense on T1-weighting.

Figure 2 Representative case of grade III bleeding hepatocellular adenoma involving a 28-year-old female who presented at the emergency department. A: Coronal computed tomography (CT) image in arterial phase shows a large hematoma in the left liver lobe (arrow); B: On the axial CT slice different bleeding adenomas are present in both lobes (arrows). Extracapsular peritoneal bleeding around the stomach is seen (triangle); C: One year later on magnetic resonance imaging in the venous phase all adenomas have decreased significantly in size.
