Grisel's syndrome as a sequela of a complicated acute mastoiditis.

Grisel's syndrome is a rare complication of ENT area infections. It consists of a non-traumatic atlantoaxial subluxation after an infectious process. Its characteristic symptom is persistent torticollis despite a resolved infection. The knowledge of this condition helps early diagnosis and treatment. We therefore present the case of a patient with Grisel's syndrome as a sequela of an acute mastoiditis complicated by a Bezold's abscess.
