Summary
A rare spinal osteochondroma caused sciatica and cauda equina compression in a teen. Surgical removal of this benign bone tumor led to a favorable prognosis.
Area of Science:
- Orthopedics
- Neurosurgery
- Oncology
Background:
- Osteochondroma is the most common benign bone tumor, typically presenting as solitary or multiple exostoses.
- Hereditary multiple exostoses (HME) is an autosomal dominant condition characterized by numerous osteochondromas.
- Vertebral column involvement by osteochondroma is uncommon, occurring in 1.3–4% of cases.
Observation:
- A 13-year-old girl with a family history of HME presented with bilateral sciatica and cauda equina compression.
- Magnetic Resonance Imaging (MRI) revealed a tumor within the L1 vertebral body.
- Surgical excision and subsequent pathological examination confirmed the lesion as an osteochondroma.
Findings:
- Spinal cord compression secondary to vertebral osteochondroma is a rare complication.
- Computed Tomography (CT) effectively analyzes tumor components and intracanalar extension.
- MRI provides superior visualization of spinal cord compression.
Implications:
- Early diagnosis and surgical decompression are crucial for favorable outcomes in spinal osteochondroma.
- This case highlights the importance of considering osteochondroma in the differential diagnosis of spinal tumors presenting with neurological deficits.
- Advanced imaging modalities like CT and MRI are essential for comprehensive evaluation and surgical planning.
