The Features of Traumatic Intrahepatic Biloma on CT and MRI

Objective:To investigate the features of traumatic intrahepatic biloma on CT and MRI.Methods:The imaging data of 10 patients with traumatic intrahepatic biloma clinically confirmed were analyzed retrospectively. Results:All patients underwent CT examination,2 cases underwent MRI examination in the course of the disease. All with hepatic parenchymal laceration,a short period of trauma,it showed low-density or large sheet long T1, long T2 signal intensity,follow-up soon showed water density or signal intensity in liver on CT and MRI.7 cases were single cystic,multiple in 3 cases.Multiple biloma along the biliary tree were pouch pocket arrangement. Except for 7 cases were naturally smaller,the remaining 3 cases were cured by surgery or ultrasound or CT-guided drainage,and whose contents were bile components.Conclusion:It has crucial significance for the diagnosis and treatment to recognize the CT and MRI features of traumatic intrahepatic biloma.
