Indeterminate liver lesions on gadoxetic acid-enhanced magnetic resonance imaging of the liver: Case-based radiologic-pathologic review

Figure 2 Hepatocellular adenoma. A 27-year-old lady with background of glycogen storage type 1 disease. A and B: Segment IVA liver lesion demonstrating mild T2 hyperintensity with atoll sign (A) and cystic foci (B); C and F: No signal drop out on out-of-phase (F) when compared to in-phase (C) T1-weighted sequence; D, E and G: There is quite homogenous hyperenhancement on arterial phase (D) with no washout on portal venous (E) and delayed (G) phases; H: Hepatobiliary phase shows contrast retention within the lesion; I: Coronal T2-weighted shows hepatosplenomegaly as features of glycogen storage disease type I. The lesion has increased in size and therefore was resected, histology revealed an inflammatory subtype hepatocellular adenoma.
