Evaluate for cause of diplopia and dizziness. History of craniotomy, meningioma. Nonenhanced head CT:Examination again demonstrate encephalomalacia in the left posterior parietal lobe as was noted on prior MRI exam. Slightly high density mass at the level of the superior sagittal sinus and right parafalcine region in the parietal region is consistent with patient's known residual meningioma which extends slightly to the left. This finding is also similar to prior exam. Subtle periventricular low attenuation of brain parenchyma in the parietal region is also similar to prior exam and may represent post therapy changes. Minimal small vessel disease of indeterminate age is also present.There is no evidence of acute intracranial hemorrhage, edema, mass-effect, midline shift or hydrocephalus.Calvarium is intact and only reveals evidence of a wide biparietal craniotomy. Visualized paranasal sinuses are well pneumatized and unremarkable. Partial opacification of right mastoid air cells and minimally of the right middle ear cavity. This finding was observed on prior MRI examination of brain.
1.No evidence of acute intracranial findings.2.Postoperative changes of biparietal craniotomy for removal of patient's known meningioma is noted.3.Residual encephalomalacia and small residual right parafalcine parietal meningioma similar to prior MRI from 2 -- 17 -- 11.
