摘　　要：目的分析肝包虫病的CT表现,探讨不同类型肝包虫病临床治疗价值。方法回顾分析36例经CT诊断及手术病理证实的肝包虫病影像资料。结果36例共发现肝包虫囊肿42个。其中单房型包虫囊肿18个,其CT表现为边缘光滑的圆形或类圆形囊性低密度灶,囊壁厚薄均匀。多房型包虫囊肿24个,包虫囊肿内可见多个子囊和不同密度的内容物,整个囊肿形态呈车轮状。实质钙化型包虫囊肿9个,表现囊内容物不同程度钙化。囊壁钙化17个,囊壁轻度至中度强化。CT在术前诊断准确率为94.4%。共15个囊肿(13个单房型,2个多房型)进行CT引导下经皮抽吸注入酒精治疗,经复查疗效肯定。结论CT对各种类型肝包虫囊肿具有较高诊断价值,而且对于单囊型包虫囊肿CT引导下介入治疗效果肯定,可达到手术切除的效果。Objective To analyze CT features of hepatic hydatid cyst and evaluate the value of clinical therapy in different types of hepatic hydatid cyst. Methods CT findings in 36 cases with pathologically proved hepatic hydatid cyst were retrospectively analyzed. Results Total 42 lesions were found in 36 cases. Eighteen lesions were of unilocular simple cyst type, which displayed as round or oval well-defined cystal hypodense lesion, the cyst wall was demonstrated uniformity, calcifications were found in the cyst wall of 17 lesions, after contrast administration, the cyst wall showed sight or middle enhancement; 24 lesions were of multiocular type with the shape of mulberry, within which daughter cyst could be seen. Solid calcified type was seen in 9 lesions, which displayed as cyst with different degree calcifications. Preoperative diagnostic accuracy of CT was 94.4%. Thirteen of 18 lesions with unilocular simple cyst type, and 2 of 24 lesions with multiocular type, were treated by percutaneous CT-guided needle aspiration using ethanol, it was an effective method after therapy. Conclusion CT is of high value for the diagnosis of hepatic hydatid cyst, it is an effective method for unilocular simple cyst by CT-guided interventional therapy, which similar to surgical resection.
