Dorsal spine osteoblastoma.

Area of Science:

• Orthopedic Oncology
• Neurosurgery
• Spinal Surgery

Background:

• Benign osteoblastoma is a rare primary bone neoplasm, accounting for less than 1% of all primary bone tumors.
• Spinal involvement by benign osteoblastoma can lead to significant neurological deficits.

Observation:

• A 20-year-old female presented with a year of progressive paraparesis and worsening dorsal back pain.
• Imaging revealed a 3.5 × 3.0 cm expansile bony lesion at the D12 vertebra, with both lytic and sclerotic features.
• The lesion compromised the bony spinal canal, causing neurological symptoms.

Findings:

• Surgical intervention involved D12 laminectomy and complete tumor excision.
• Histopathological confirmation of benign osteoblastoma was obtained.

Implications:

• This case highlights the importance of considering benign osteoblastoma in the differential diagnosis of spinal tumors presenting with progressive neurological deficits.
• Complete surgical excision is crucial for managing spinal benign osteoblastoma and preventing recurrence or further neurological compromise.
• Early diagnosis and intervention can significantly improve patient outcomes and quality of life.
