Diagnosis: Giant cell tumor
Discussion
Findings:
C-spine lateral; Expansile osteolytic lesion is noted at body of C2 extending to odontoid process
CT; Expansile, markedly osteolytic bone lesion is noted in body of C2, base, both pedicle and neural arch of odontoid process.ㅁ Cortical margin is relatively spared.
MR; Iso-signal intensity on T1WI osteolytic lesion is noted at body of C2 This lesion shows high signal intensity with fluid-fluid level on T2WI and heterogenous enhancement. On sagittal reconstruction image, this expansile osteolytic lesion is extended to pedicle, posterior element and odontoid process. Cortical margin is preserved.
Differential Diagnosis:
Aneurysmal bone cyst
Multiple myeloma
Metastasis

Younger than long bone lesion
Site; sacral body(mc) other vertebral body
F:M=3:1
Expansile, osteolytic lesion Fluid-fluid level
