Right-sided weakness. Motion artifact degraded image quality significantly.However, on diffusion-weighted image, there are multiple high signal intensities especially on the left precentral gyrus, posterior central gyrus as well as occipital lobe with corresponding restricted diffusion on ADC map indicating acute ischemic infarctions. Corresponding T2 weighted images do not show evidence of high signal intensity, thus the possibility of T2 shine through might be very slim.There is no evidence of acute hemorrhagic lesion.Minimal non specific small vessel ischemic disease on FLAIR images.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Provided that the examination quality has been degraded due to motion artifacts, the possibility of acute ischemic infarctions without evidence of hemorrhagic transformation on the left frontal and parietal lobes is high as described above. Non specific small vessel ischemic disease.
