Multi-slice CT findings of primary biliary cirrhosis

Objective To retrospectively analyse the multi-slice CT(MSCT) images obtained in patients with primary biliary cirrhosis(PBC).Methods Between February 2008 and January 2010,24 patients with PBC and 30 subjects with hepatitis B-induced cirrhosis(control group) were performed routine abdominal MSCT.Liver volume measuring,abdominal lymph notes,collateral circulation and gallbladder disease were analyzed in that two group's patients.Results In our study,CT evidence of lymphodenopathy was found in 75.0% and 16.7% of patients in PBC and in hepatitis B-induced cirrhosis,respectively.Cholecystitis was seen in 70.8% and 20.0% of patients in PBC and in control group,respectively.The lymphodenopathy and cholecystitis were more common in PBC than in control group and there were significant difference between the two groups(x2=18.555,P0.01 and x2=14.091,P0.01).The liver volume change and collateral circulation in two groups were not statistically significant(P0.05).Conclusion The lymphodenopathy and cholecystitis are more frequent MSCT findings in primary biliary cirrhosis than that in hepatitis B-induced cirrhosis.The liver volume change and collateral circulation in PBC are similar to that in the control group.
