Abstract：Objective: To observe the ultrasonographic manifestations of hepatic cystic echinococcosis, and to compare with the results of surgical pathology. Methods: The clinical data of 158 patients (158 lesions) with hepatic cystic echinococcosis in the Ganzi Tibetan Autonomous Prefecture People's Hospital from January 2022 to December 2024 were retrospectively analyzed. All patients received ultrasound examination before surgery, and their ultrasonographic data were collected and the involvement conditions of lesion in blood vessels and bile ducts were assessed. The diagnostic efficiency of ultrasound on hepatic cystic echinococcosis typing and detection conditions of vascular involvements and bile duct involvements were evaluated by taking surgical pathology as standard. Results: Ultrasonography of 158 patients (158 lesions) with hepatic cystic echinococcosis showed that there were 19, 37, 23, 9, 58 and 12 lesions of CE1, CE2, CE3a, CE3b, CE4 and CE5 types, respectively. With surgical pathology as standard, the accuracy rates of ultrasound in diagnosing CE1, CE2, CE3a, CE3b, CE4 and CE5 types were 90.00% (18/20), 100% (35/35), 95.83% (23/24), 81.82% (9/11), 98.21% (55/56) and 100% (12/12), respectively. The overall accuracy of ultrasound diagnosis of cystic echinococcosis disease typing was 96.20 per cent (152/158). The detection rates of vascular involvements in different parts by ultrasound were lower than those by surgical pathology (P<0.05). The detection rates of bile duct involvements by ultrasound were also lower than those by surgical pathology (P<0.05). Conclusion: The ultrasonographic manifestations of hepatic cystic echinococcosis have obvious characteristics. The diagnosis of disease typing is consistent with the results of surgical pathology, but it has certain limitations in the diagnosis of vascular and bile duct involvements.
