Abstract:
Objective To analyze the CT characteristics of atypical hepatic hemangiomas.Methods 20 patients with atypical hepatic hemangiomas confirmed by pathology were collected.All patients underwent plain and contrast-enhanced CT scan and the atypical CT findings were analyzed retrospectively.Results There were 24 lesions in 20 patients,among which 21 lesions were round in shape and 3 lesions were irregular.Scars and necrosis were found in 14 lesions,calcifications in 2 lesions and capsule contractions in 2 lesions.Contrast-enhanced CT showed significant peripheral enhancements with incomplete fill-in in delayed phase in 13 lesions, homogeneous enhancements in arterial phase and continuous enhancements in portal and /or delayed phase in 2 lesions,central patchy enhancements in the arterial phase and reverse enhancements from center to edge in portal and/or delayed phase in 4 lesions, mild to moderate peripheral enhancements in the arterial phase in 3 lesions,and no enhancements in the arterial phase and mild enhancement in portal and/or delayed phase in 2 lesions.In addition,2 cases had arteriovenous fistulas.Conclusion As for atypical hepatic hemangioma,it is necessary to comprehensively observe and analyze the delicate signs for correct diagnosis and differential diagnosis.
