Abstract

Cerebral alveolar echinococcosis (AE) is rare and mostly associated with liver involvement. We report an exceptional case of a 62-year-old man with a hereditary hemorrhagic telangiectasia harboring a primary cerebral AE mimicking neurocysticercosis with >100 cerebral lesions and without liver involvement.

Keywords: Echinococcus multilocularis; abscess; cerebral; primary lesion.

Sagittal T1-weighted contrast-enhanced (A–D) and fluid-attenuated inversion recovery (E–H) magnetic resonance image (MRI) showing enhancement of multiple lesions before treatment with albendazole with intense peripheral edema (A, E) and after 4 weeks of treatment (B, F). Six weeks after the end of treatment, the MRI showed a relapse with new lesions (C, G). After 6 months of albendazole, the MRI showed an improvement of the lesions and the edema (D, H). Abbreviation: FLAIR, fluid-attenuated inversion recovery.
