| 目的 探讨肝包虫病的CT和MRI表现。方法 临床手术、病理证实的肝包虫病42例,就其CT和MRI表现回顾性分析并就相关文献进行复习。结果 本组肝细粒棘球蚴病占85.71%,蛋壳样或条带状钙化、"囊内囊"、"飘带征"等为其主要表现;肝泡球蚴病占14.29%,钙化、"小泡征"、"半岛征"及囊腔或液化、坏死等为其主要表现;MR T2WI显示囊壁及纤维间隔、飘带征等优于CT,但钙化显示逊于CT。结论 CT和MR均可诊断肝包虫病,CT在综合诊断方面优于MR。 |

| Objective To observe the CT and MR features of hepatic hydatid cyst, and to evaluate the diagnostic value of CT and MR. Methods CT and MR images were retrospectively analyzed in 42 patients with pathologically proved hepatic hydatid diseases, and the relative articles were reviewed. Results Hepatic echinococcosis granulosus occured in 85.71% patients, among which ring like pattern calcification, the ribbon calcification, multiple daughter vesicles and detached membranes within cyst were the main findings. Hepatic echinococcosis alveolaris occured in 14.29% patients, whereas the main finding included calcification, small vacuoles, peninsula sign, geographic sign and colliquative necrosis. For the diagnosis of hepatic hydatidosis, MR was better than CT in the judgement of the cyst wall, detached membranes and fibrous septum, but was inferior to CT in displaying calcification sign. Conclusion Hepatic hydatidosis can be diagnosed either with CT or MR, CT is superior to MR in integrated diagnosis of this disease. |
