Imaging Findings of Solitary Hepatic Biliary Hamartoma in Adult: A Report of 3 Cases / 实用放射学杂志

ABSTRACT

Objective To study imaging findings of solitary hepatic biliary hamartoma in adult in order to improve the understanding of this disease.Methods The imaging findings of solitary hepatic biliary hamartoma proved by surgery and pathology in 3 cases were retrospectively analyzed.There were one male and two female,the age was 28,43 and 76 years old respectively.B-ultrasound and CT were performed in three cases and MRI was done in one case.Results The masses ranged in diameter from 2 cm to 4 cm.The lesions were inhomogeneous slightly hypoecho or slightly hyperecho on B-ultrasound,slightly homogeneous or inhomogeneous hypodensity on plain CT scan,slight or medium homogeneous or inhomogeneous enhancement and delayed enhancement on contrast-enhanced CT scan,slight low signal intensity on T1WI and slight high signal intensity on T2WI,and rim enhancement on post-gadolinium images.Conclusion The findings of solitary hepatic biliary hamartoma in the adult are not of characteristics.It may be similar to common hepatic mass,such as metastasis,hepatic abscess and hepatic cavernous hemangioma.
