 There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is minimal nonspecific periventricular white matter T2 hyperintensity. The brain parenchyma otherwise appears unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. However, there is what appears to be a partially-imaged medial course of a prominent left vertebral artery or vein at the level of C2, where the vessel appears to indent the vertebral body. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. Minimal nonspecific periventricular white matter signal abnormality, which may represent chronic ischemic effects, but no evidence of acute cerebral infarction.2. Partially-imaged medial course of a prominent left vertebral artery or vein at the level of C2, which may be an anatomic variant, although dedicated vascular imaging of this region may be helpful for further clarification.
