Transient cerebral ischemic attack, unspecified [G45.9], Reason for Study: ^Reason: assess vasculature, space occupying lesion? Cerebellar? History: see MRA Brain MRIThere is no evidence of acute ischemic or hemorrhagic lesion on this scan.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.Mucosal thickenings on frontal, ethmoid and sphenoid sinus.Brain MRAMotion artifacts degraded image quality significantly.3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal. No evidence of occlusion or luminal stenosis on bilateral distal ICAs, MCAs, ACAs and vertebrobasilar system. Medium to small vessels (distal to the MCA M1 segment for example) cannot be evaluated with this scan. No evidence of intracranial arterial aneurysm.
1. No evidence of acute ischemic or hemorrhagic lesion.2. No evidence of intracranial arterial major artery occlusion. No evidence of intracranial arterial aneurysm. Comment: if precise evaluation of intracranial arterial system is clinically indicated, CTA of head can be considered.
