ABSTRACT
Objective To investigate the CT features of hepatic focal nodular hyperplasia (FNH) in children.Methods Thirteen patients with FNH,which was confirmed by postoperative pathology,were enrolled retrospectively.Plain and contrast CT were performed on all patients before operation.The CT imaging features of FNH including size,shape,density,style of contrast were analyzed retrospectively and compared with pathology.Results There were 13 patients with 16 lesions,8 lesions were found in the right lobe,5 lesions in the left lobe and 3 lesions involving both lobes.The tumor size ranged from 5.5 cm to 11.5 cm (media size 7.5 cm) in diameter.Histologically,2 cases were typical type,11 cases were atypical type.The lesions were regular morphology in 12 cases and 1 case with capsule.On plain CT,the lesions were isodensity (n=1) or slightly low-density (n=12).In 2 typical type lesions,there were slit-like,stellate-shaped low density central scars.Arterial phase demonstrated that 12 cases were significantly enhanced and 1 case showed mild enhancement.The central scar was not enhanced.In 12 cases,thickened and torturous arteries were seen.The enhancement was reduced at the portal venous phase in all the lesions,with 10 cases showing slightly higher density,2cases isodensity and 1 case low-density.Two cases showed mild enhancement of the central scar.The enhancement of the solid portion in all lesions decreased at the delay phase,with 12 cases showing isodensity and 1 case slightly low density.Two cases with central scar showed delayed enhancement with slightly higher density.Conclusion The CT features of FNH in children are diversified but distinctive which are related with postoperative pathological findings.Combining with clinical symptoms and CT features can be helpful for the early diagnosis of FNH in children.
