We report one case of uncommon spinal hydatid cysts particular by its localization. It is intradural, localized with predilection in the big cistern cerebello-medullar. There is no involvement of adjacent vertebral discs and ligaments. We specify characteristic imaging features and polymorphism of this affection who can affect all anatomical structures. We emphasize MRI for diagnosis and follow-up in search for residual or recurrent lesions
