65-year-old female with altered mental status. Evaluate for CVA. Patient is status post right parietal craniotomy with region of encephalomalacia seen in the right precentral gyrus, involving the right centrum semi-ovale as well. Patchy hypoattenuation areas are also seen in bilateral corona radiata. These findings appear relatively unchanged on comparison to previous MRI from 2006. There is no evidence of acute intracranial hemorrhage, mass or edema. Hyperdense lesion seen in the medial right temporal lobe (series 4, image 9) also appears similar to prior studies. The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
Postsurgical changes appearing similar to prior MRI from 2006. Please note that lack of IV contrast limits evaluation for tumor, and CT is insensitive to early detection of CVA. Consider contrast-enhanced CT or MRI to evaluate for tumor recurrence or stroke if clinically needed.
