AIM: To study the liver and spleen volume variations in hepatic fibrosis patients at different histopathological stages.METHODS: Multidetector computed tomography (MDCT) scan was performed in 85 hepatic fibrosis patients. Liver volume (LV) and spleen volume (SV) were measured. Fifteen healthy individuals served as a control group (S0). The patients were divided into stage 1 (S1) group ( n = 34), stage 2 (S2) group ( n = 25), stage 3 (S3) group ( n = 16), and stage 4 (S4)group ( n = 10) according to their histopathological stage of liver fibrosis.RESULTS: The LV and standard LV(SLV)had a tendency to increase with the severity of fibrosis, but no statistical difference was observed in the 5 groups (LV: F = 0.245, P = 0.912; SLV: F = 1.902,P = 0.116). The SV was gradually increased with the severity of fibrosis, and a statistically significant difference in SV was observed among the 5 groups( P < 0.01). The LV/SV ratio and SLV/SV ratio were gradually decreased with the aggravation of hepatic fibrosis, and statistically significant differences in both LV/SV and SLV/SV were found among the 5 groups ( P< 0.01).CONCLUSION: The absence of obvious LV reduction in patients with chronic liver disease may be a morphological index of patients without liver cirrhosis. The SV is related to the severity of fibrosis, and the spleen of patients with advanced fibrosis is enlarged evidently. The LV/SV ratio and SLV/SV ratio are of a significant clinical value in the diagnosis of advanced liver fibrosis.
