Objective: Osteoblastoma and aneurysmal bone cyst are rare pathologic entities of the spine, accounting for less than one per cent of all bone tumours. An aneurismal bone cyst associated with or secondary to other osseous spinal lesions is an exceptional finding. The authors report the unusual case of an aneurysmal bone cyst adjacent to an osteoblastoma of the cervical vertebral column.

Methods: A 13-year-old female with a history of minor cervical trauma was admitted with neck pain for three months. Computed tomography scans and magnetic resonance imaging of the cervical spine revealed an osteolytic lesion in the spinous process of C5 with surrounding paravertebral soft-tissue density mass and involvement of the spinal canal suggesting a solitary aneurysmal bone cyst. Microsurgical excision via a laminectomy with histological examination confirmed the diagnosis of a presumptive aneurysmal bone cyst associated with an unsuspected benign osteoblastoma and led to complete resolution of the patient's symptoms. No recurrence was noted after a follow-up of one year.

Results: A rare case of initially unexpected simultaneous occurrence of symptomatic spinal cervical osteoblastoma associated with an aneurysmal bone cyst is described that could be successfully treated by microsurgery and finally confirmed by histopathological investigation.

Conclusions: Spinal osteoblastoma and aneurysmal bone cyst can be associated and their appearances may mimic each other. The coincidence of two different pathological entities with similar clinical, radiological, and histological features has to be considered in differential diagnosis of spinal osseous lesions to allow adequate patient treatment and follow-up.
