44 years Female (DOB:2/14/1972)Reason: eval for ischemia; also eval for changes in white matter lesions from previous MRI in Jan '16 History: L face numbnessPROVIDER/ATTENDING NAME: MAHESH PADMANABAN Since the previous examination the patient is developed a new enhancing lesion in the left trigeminal root inlet within the pons on the left side.The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a mild degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images. This has not changed significantly compared to the previous exam.A punctate focus of susceptibility effect is redemonstrated in the left temporal lobe at the inferior temporal gyrus subcortical white matter which is stable compared to prior exam and not readily appreciated in other pulse sequencesNormal 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.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Since prior examination patient developed a new lesion in the left pons in the expected location of the left trigeminal root inlet. Associated contrast enhancement suggests that this is acute or subacute2.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 nonspecific.
