Soft tissue mass measuring 2 x 2.5 x 2 cm centred on the left cavernous sinus, wrapping around the posterior clinoid process and dorsum sellae shows that the contrast enhancement. No further enhancing lesion identified elsewhere in the brain. The left intracranial internal carotid artery is not significantly narrowed by the mass. No intracranial aneurysm.
Aortic arch anatomy is conventional. Bilateral carotid bulb calcified plaque results in less than 15% stenosis on the left and approximately 30% stenosis on the right. The vertebral arteries are normal in appearance.
Extensive mucosal thickening of the right maxillary antrum again demonstrated.
Conclusion
The contrast enhancing mass centred on the left cavernous sinus is most in keeping with a meningioma.
