Abstract:
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.
