Summary
Osteoblastoma, a rare bone tumor, can present with atypical imaging findings. Enhanced MRI with gadolinium is crucial for early detection and diagnosis of this spinal neoplasm.
Area of Science:
- Orthopedic Oncology
- Neurosurgery
- Radiology
Background:
- Osteoblastoma is a rare, benign bone-forming tumor.
- This case highlights an osteoblastoma in the 10th thoracic vertebra pedicle.
Observation:
- The patient presented with nocturnal back pain unresponsive to salicylates.
- Initial imaging (X-ray, CT, non-contrast MRI) showed subtle changes.
- Bone scintigraphy indicated increased osteoblastic activity.
Findings:
- Repeat MRI with gadolinium contrast revealed focal enhancement, aiding diagnosis.
- Histopathologic examination after pediculectomy confirmed osteoblastoma.
- The patient remained symptom-free 15 months post-surgery.
Implications:
- Osteoblastoma imaging can be atypical, challenging initial diagnosis.
- Gadolinium-enhanced MRI is superior for visualizing osteoblastoma.
- Early detection and surgical removal of osteoblastoma are vital to prevent bony structural damage.
