Benign Hepatocellular Tumors in Children: Focal Nodular Hyperplasia and Hepatocellular Adenoma
Adenoma associated with CPSS. Aspect on MRI at diagnosis and 10 months after surgical closure of the shunt: (a) T2 WI-balanced sequence shows the CPSS consisting of a patent ductus venosus. Note that the tumor is not easily visible in this sequence. (b) The 4 cm diameter HCA lies in segment 8, and it is better seen on T2 WI and appears heterogeneous and mainly hyperintense compared to the surrounding liver. MRI performed 10 months after surgical closure of the shunt (c) shows the complete disappearance of the tumor (d).
