Analysis of clinical image features of hepatoblastoma in adults / 中华普通外科杂志

ABSTRACT

Objective To investigate CT and MRI features of hepatoblastoma in adults.Methods CT and MRI findings of 8 cases of adult hepatoblastoma were retrospectively analyzed.Results (1) 75.0％ of the tumors was located in the right lobe of the liver and 25.0％ in the left lobe of the liver.(2) The maximum diameter of the tumor was averaged at (8.2±5.5)cm,and the maximum diameter of ＞ 5 cm was 62.5％.(3) Most tumors have a complete or incomplete false envelope,and the boundary is clear.(4) 75.0％ tumors were of necrocystic degeneration with calcification or bleeding in 25.0％ cases.(5) CT flat scan showing uniform low density or low density,MRI scanning T1WI was low signal,T2WI,T2WI fat suppression and DWI were high in parenchyma.(6) To strengthen substantial part in mild and moderate arterial uneven improved or ring slightly improved,portal venous phase continued mild reinforcement,delay slow exit accounted for 75.0％,reinforced psuedocapsule was mild.(7) The adjacent organs are under pressure deformation.(8) All patients underwent tumor resection and were followed up for 3 to 24 months.Conclusions CT and MRI characteristics of hepatblastoma in adult are specific and help improve the diagnostic accuracy of the disease.
