History of meningioma, post surgery follow-up. There is no evidence of acute ischemic or hemorrhagic lesion on the scan.Redemonstration of postoperative changes including suboccipital, left craniotomy encephalomalacia on the cerebellar vermis and left cerebellar hemisphere, no change since prior scan.Homogeneously enhancing thickened medial left side the tentorium represent residual meningioma is measured around 12 mm x 20 mm x 12 mm, no change since prior scan.Multifocal scattered bihemispheric high signal intensities on white matter on FLAIR imaging indicating nonspecific small vessel disease, no change since prior scan.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.Retention cyst on the left maxillary sinus, no change since prior scan.
1. Stable postoperative status of tentorial meningioma.2. No change of the size and MR characteristics of residual lesion on the medial left tentorium comparing to prior scan.
