history of meningioma with prior resection. Follow up imaging. No evidence of acute ischemic or hemorrhagic lesion on this scan.Redemonstration of prior midline parieto-occipital craniotomy with minimal gliotic changes of right parietal lobe superior lobule. No change of minimal thickening and enhancement along the posterior falx especially on the right side does not show any significant difference comparing to prior examination. The flow void of the adjacent superior sagittal sinus seems to be preserved.No significant fluid collections. No new foci of signal abnormality are seen. Mild periatrial FLAIR high signal intensities as well as a linear focus of the left frontal lobe are unchanged and nonspecific. There is no new enhancing lesions. The ventricles are stable and normal in size.Fluid collections on the left maxillary sinus.
1. No evidence of acute ischemic or hemorrhagic lesion.2. No abnormal enhancement.3. Post operative changes, no unusual finding. No evidence of recurrence of tumor.
