Figure 1. T2-weighted and post contrast T1-weighted contrast-enhanced MR-images reveal bilateral cerebellopontine angle masses.
Figure 2. T2-weighted and post contrast T1-weighted contrast-enhanced MR-images reveal a contrast enhancing lesion within the cord (c2-3) associated with a rostral and caudal peri-tumoral cyst cavity lined by hemosiderin.

8. Please add any suggestions or comments regarding this case:
- Good test
- This is a great case for discussion. I felt last month's case on Type II Odontoid Fracture was just too easy & straight-forward, could be answered by a junior resident, and didn't really merit "Case of the Month". Glad we have a more thought-provoking case for this month!
- thank alot for your effort for better future for all of us.
- surgery fore c1-c2 , with decompresion of posterior fossa up to sinus
- i do spinal tumor resection ,then left cp angle and do radio surgery for rt cp angle tumor
- Very interesting, challenging case!
