title: Focal hepatic lesions mimicking cavernous hemangioma supplied by the portal vein.
abstract: We report that imaging findings of focal hepatic lesion mimicking cavernous hemangioma supplied by the portal vein, which showed delayed enhancement on CT and hyperintensity similar to that of cerebrospinal fluid on T2-weighted MR images. Biopsy specimen showed the dilated portal veins and hyperplastic change in the surrounding liver parenchyma. CT during arterial portography (CTAP), in particular single-level dynamic CTAP, could clearly depict the abnormal dilated portal vein in the lesion and facilitated the diagnosis of this condition.
