CT findings of pediatric hepatoblastoma and correlation with pathological subtypes / 中国医学影像技术

ABSTRACT

Objective To explore the CT findings of pediatric hepatoblastoma and its correlation with pathological subtypes.Methods CT findings and pathological characteristics of 110 patients with hepatoblastoma confirmed by pathology were retrospectively analyzed.Results The locations of the tumor were right lobe (67/110,60.90％),right and left lobe (25/110,22.72％),left lobe (15/110,13.63％) and caudate lobe (3/110,2.72％).The average tumor size was (287.14±272.36) cm3.Most cases were solitary (94/110,85.45％) and round shape (96/110,87.27％).Most cases were well defined (86/110,78.18 ％).Necrosis were irregular in 102 cases,calcification were in 60 cases.Lung metastases were common (23/110,20.90 ％) and vessel involvement were common (56/110,50.90 ％).Lymph node metastasis was in 5 cases.Calcification and homogeneous enhancement in different pathological types had statistically significance (both P ＜0.001).Conclusion CT is helpful for pre-operation and pathological diagnose.
