Cerebral hydatid disease CT and MR findings

In this study, we reviewed the computed tomography (CT, n = 9) and magnetic resonance (MR, n = 5) imaging findings of 11 patients with pathologically confirmed cerebral hydatid disease. Among our patients, there were 10 cases of Echinococcus granulosus and 1 case of Echinococcus multilocularis. Common CT and MR imaging findings of E. granulosus lesions were well-defined, smooth thin-walled, spherical, homogeneous cystic lesions with no contrast enhancement, no calcification, and no surrounding edema. E. multilocularis lesions showed calcified round, solid pattern with definite margins, contrast enhancement, and Surrounding edema. (C) 2002 Elsevier Science Inc. All rights reserved.
