Aneurysmal bone cyst in a 27-year-old female with cervical pain and weakness of the right upper limb. Axial CT scan reconstruction (a) shows an expansile, lytic lesion within the right neural arch and the vertebral body of C6 (white arrows). The mass invades epaxial and hypaxial region (arrowheads). Axial T2WI (b) demonstrates fluid–fluid levels (black arrows). Sagittal T1WI (c) and contrast-enhanced T1WI (d) show cystic areas. The lesion involves two adjacent vertebral levels. The yellow star shows the epicentre of the mass
