Fig. 1From: C1-C2 subluxation in enthesitis-related arthritis: two case reports and literature review of ten casesComputed tomography of cervical spine showing C1-C2 subluxation in the present patient with enthesitis-related arthritis. Cervical spine computed tomography (CT) reveals widened lateral space between the odontoid process and right arch of the atlas in coronal view (black arrow, A) and in axial view (white arrow, B). Cervical spine CT with three-dimensional reconstruction in top-down view (C) depicts rotatory subluxation with asymmetric interspaces between the odontoid process and the arches of the atlas.
