Cervical Osteochondroma Causing Cord Compression: A Case Report and Literature Review

Osteochondroma is a benign cartilaginous tumour that typically arises in the growth plate of long bones, whereas involvement of flat bones is uncommon. Spinal osteochondromas are rare, accounting for approximately 4% of all spinal neoplasms. A rare case of cervical osteochondroma arising in the subaxial cervical spine in a 43-year-old woman is presented. The patient had a 2-year history of neck pain and swelling, followed by radicular pain radiating to the left upper limb for 2 months. Radiological evaluation led to a provisional diagnosis of cervical osteochondroma, and extraperiosteal excision of the tumour was performed. Histopathological examination confirmed the diagnosis of benign osteochondroma. Following surgery, both neck pain and left-sided radicular pain resolved, with no evidence of recurrence at the 3-year follow-up. Surgical excision remains the primary treatment for osteochondroma and is associated with a low risk of recurrence. In cases of cervical osteochondroma, surgical treatment is recommended to prevent potential complications, particularly in symptomatic patients.
