- Mass effect causes scalloping of vertebral body, scoliosis and enlargement of neural foramina
- When hemorrhage occurs within lesion, sudden worsening of clinical symptoms with leg weakness and sphincter disturbances
- Also causes subarachnoid bleeding and siderosis
- Spontaneous dissemination along craniospinal axis possible, extradural spread also seen post operatively. Post-op radiotherapy helps to reduce recurrence
- MRI: iso- to hyperintense on T1 (mucin). hyperintense on T2.
