Cerebral hydatid disease CT and MR findings

Abstract

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.
