Patient with episodes of nonresponsiveness, weakness for past two days, rule out TIA. There is no evidence of intracranial hemorrhage, mass or midline shift. Patchy areas of subcortical and periventricular white matter hypodensity likely represent small vessel ischemic disease, age indeterminate by CT. These changes appear minimally more prominent than on the prior study. If there is concern for an acute stroke, an MRI is recommended for further evaluation.The ventricles appear unchanged compared to the prior examination. Small choroid plexus cysts appear stable since 2002.The calvaria and skull base are radiographically normal. The left sphenoid sinus demonstrates evidence of chronic inflammatory changes but now appears mostly aerated. The remaining visualized paranasal sinuses and mastoid air cells are normally pneumatized.
