Summary
Spinal schwannomas can mimic intramedullary tumors on MRI due to cystic components. Recognizing dorsal cystic masses aids in differentiating these extramedullary tumors from intramedullary spinal cord lesions.
Area of Science:
- Neurosurgery
- Radiology
- Pathology
Background:
- Spinal schwannomas are common intradural extramedullary tumors.
- They can present with cystic components, mimicking intramedullary lesions on magnetic resonance imaging (MRI).
