Abstract: Objective To investigate the computed tomography (CT) manifestations of microvascular invasion (MVI) and recurrence of small hepatocellular carcinoma (sHCC) under the background of liver cirrhosis. Methods Seventy-two patients with sHCC and cirrhosis admitted to our hospital from June 2015 to June 2018 were selected as the research objects. Patients were divided into a MVI group (n=32) and a non-MVI group (n=40) according to the presence of MVI. All objects were followed up for 3 years after operation, and were divided into a recurrence group (n=19) and a non-recurrence group (n=53) according to the recurrence of sHCC. CT examination was performed before surgery. The results of CT examination between MVI group and non-MVI group were compared. The results of CT examination between recurrence group and non-recurrence group were also compared. Results The proportions of patients with complete capsule, defective capsule and no envelop in MVI group were 28.13%, 46.86% and 25.00%, respectively, while those in non-MVI group were 62.50%, 27.50% and 10.00%, respectively. The differences between the 2 groups were statistically significant (P<0.05). The proportions of patients with enhanced and smooth tumor margins were 78.13%, 34.38% in MVI group, and 42.50%, 77.50% in non-MVI group, respectively. The differences between the 2 groups were statistically significant (P<0.05). The proportions of complete capsule, defective capsule and no envelop in the recurrence group were 21.43%, 46.43% and 32.14%, and those in the non-recurrence group were 63.64%, 29.55% and 6.82%. The differences between the 2 groups were statistically significant (P<0.05). The proportions of patients with enhanced and smooth tumor margins were 92.86%, 32.14% in the recurrence group, and 36.36%, 75.00% in the non-recurrence group, respectively. The differences between the 2 groups were statistically significant (P<0.05). Conclusion Preoperative CT examination has high predictive value for MVI and recurrence of sHCC in patients with cirrhosis.
