RADIOLOGY: HEPATOBILIARY: Case# 32814: FNH. Four year old girl with a history of congenital heart diseaseIt was felt that this lesion represents a benign solid hepatic tumor. It does not have the features of the vascular malformations such as a cavernous hemangioma or a hemangioendothelioma. The morphologic appearance and the minimal interval growth in a two and a quarter year period are against a primary or secondary malignant tumor such as hepatoblastoma or even the fibrolamellar variant of HCC. Diagnostic considerations that one is left with include FNH, mesenchymal hamartoma and hepatic adenoma. The hepatic adenoma is rare in children and the mesenchymal hamartoma is usually cystic. I understand the previous biopsy showed FNH and if the pathologic report at that time showed the presence of biliary radicals(present in approx. 60% of FNH), then a HIDA scan may add further weight to that diagnosis(in which case the lesion should take up the biliary tracer but fail to excrete it).
