CT is insensitive for the early detection of acute nonhemorrhagic cerebral infarction. The CSF spaces are appropriate for the patient's stated age with no midline shift. A focus of diffusion restriction is present in the left pons in a paramedian location.No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.There is a mild degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images.Incidental note is made of partial empty sella.The visualized portions of the paranasal sinuses demonstrate a mucous retention cyst in the left maxillary sinus. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits demonstrrate old left orbital medial blowout.
1.There is an acute lacunar cerebral infarction in the left pons.2.Periventricular and subcortical white matter signal changes of a mild degree are present which are nonspecific. They could be vascular related, related to demyelination, trauma, vasculitis, sarcoid. They are nonspecific3.
