Right-sided hemiparalysis. There is a patchy high signal intensity on FLAIR and T2-weighted images on the left side of the pons indicating chronic ischemic lesion. However, there is no evidence of acute ischemic or hemorrhagic lesion on the scan.Minimal scattered hyperintensities on the bilateral periventricular white matter indicate minimal nonspecific small vessel disease. Most of low attenuations on CT scan are more likely representing perivascular space.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. 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.
No evidence of acute ischemic or hemorrhagic lesion.Chronic ischemic lesion on the left side of pons as described above.Minimal nonspecific small vessel disease.
