INTRACRANIAL MRA :
There are small, well-circumscribed (approximately 2-3 mms in diameter) lesions in the region of the tip of the basilar artery and the distal aspect of the left posterior cerebral artery. These may represent small aneurysms.

The MRI/MRA features are suggestive of :
1. Areas of altered signal intensity within the quadrigeminal cistern, superior cerebellar cistern and few of the sulci in the parietal lobes bilaterally and may represent subarachnoid hemorrhage.
