Introduction
- Occurrence of multiple primary brain tumors is uncommon
- Chordoid meningioma is a rare isthological entity
- The association of two different subtypes meningiomas in the same region have not yet been reported

Widened Pterional approach
- Removing the anterior firm and larger tumor (intra-op histo exam revealed a chordoma) WHO II
- Bone and muscle were infiltrated (Simpson I)
- Cleavage between the lesions
- Posterior mass was easily removed (intra-op histo exam revealed a transitional meningioma) WHO I

Conclusion
- At nine months F.U. patient is still free disease
- No radiotherapy was delivered
- Control MR showed no recurrence
