| Abstract |
Introduction: Osteoblastoma is a benign tumor, representing 1 to 5% of the primary bone tumors. The incidence of osteoblastoma involving the spine reaches 36%, from which even 40% affect the cervical segment, more commonly the posterior elements. Young male people are the most affected. The diagnosis is frequently late, as it usually courses with chronic cervical pain as the only symptom. However, when there is mass effect on nerve roots or the spinal cord, neurological manifestations such as radiculopathy or myelopathy do occur as well. The most sensitive radiographic examination used in osteoblastoma's evaluation is the bone scan. The treatment goal is complete surgical resection, which allows the complete regression of complaints and decrease the likelihood of recurrences. Methods: Here we report a case of a 16 years old Brazilian patient who presented since 2 months with left cervical pain as single symptom, without irradiation and non-responsive to medications such as non-steroidal anti-inflammatory drugs. In further investigation, a spine computed tomography revealed destruction of the posterior C3 arch and tissue invasion. The patient underwent a decompressive surgery with a tricortical iliac crest graft between C2 and C4 and arthrodesis with anterior cervical plaque from C2 to C4. Seven days later, a side mass screw was placed at the right side of C2, C3 and C4 through posterior access. Results: The histopathological examination was suggestive of osteoblastoma. After surgical excision, the patient had total resolution of the symptoms and no sequels. At the three-year follow-up, the patient was asymptomatic, had no restrictions on daily activities, and to date there has been no evidence of recurrence. Conclusion: During investigation of chronic spine pain cases in young patients, it is essential to consider osteoblastoma as differential diagnosis, aiming an early and complete surgical resection to avoid progression of bone destruction and neurological deficits as well as resolve the symptoms and prevent recurrences. |
