Assessment of extrahepatic abdominal extension in primary malignant liver tumours of childhood.
Imaging is a crucial part of the evaluation of children with primary liver malignancies. In addition to staging the intrahepatic extent of the tumour, the 2005 revision of the PRETEXT system specifies certain criteria for assessment of extrahepatic disease. This article reviews the imaging findings of two of these criteria: direct extrahepatic extension of the tumour (E1, E1a, E2, E2a) and tumour rupture at diagnosis (H1).
