Abstract: Objective The aim of this study was to summarize morphology and enhancement feature of hepatic hemangioma (HH)by multi-slice spiral CT (MSCT). Methods A total of 110 patients with HH were encountered in our hospital between January 2021 and December 2023, and all patients underwent MSCT scan. The morphology and blood supply was analyzed by 3D software. Results Of the 110 patients with HH, MSCT plain scan showed 152 lesions, including 68 (61.8%) single lesions and 42 (38.2%) multiple lesions; there were 104 (68.4%) lesions in right lobe of liver and 48 (31.6%) in left lobe; there were 122 lesions (80.3%) with circular or circular-like shape with edges clear and 30 lesions (19.7%) with irregular edges; 128 (84.2%) lesions were smaller than 10 cm and 24 (15.8%) were larger than 10 cm; 144 (94.7%) lesions were with low density shadow and 8 (5.3%) lesions with high density shadow; with spotty or nodular enhancement at edge or in center of lesions at arterial stage accounted for 83.6%, and no enhancement for 16.4%; there were 118 (77.6%) lesions with reduced enhancement and 34 (22.8%) lesions without enhancement at portal stage; of 34 lesions without enhancement at portal stage, 18 lesions(52.9%) presented with enhancement and 16 lesions(47.1%) left still without enhancement; tumor volume and enhancement volume in large HH lesions were (318.4±53.1) cm³ and (52.0±9.1) cm³, both significantly larger than [(131.7±25.8) cm³ and (38.4±7.9) cm³,P<0.05], while enhancement ratio was (16.3±4.6) %, significantly lower than (29.1±12.0) % (P<0.05) in small lesions. Conclusion MSCT scan could show HH morphology and enhancement feature, which might help clinicians determine the quality of intrahepatic lesions and make appropriate diagnostic and therapeutic measures.
