[Cervical hydatid disease with retropharyngeal involvement: a case report].

Hydatid disease involves the bones in 0.5 to 2% of cases, with 44% of these cases at the level of the spine. The cervical spine is a rare location, with a risk of spinal cord compression and recurrences. The Authors report a case of a young male admitted for progressive quadriplegia secondary to cervical spine hydatidosis, extending towards the retropharynx that was evaluated by CT and MRI.
