Benign neoplasm of meninges, unspecified [D32.9], Reason for Study: ^Reason: S/p tumor resection 4/2013 and SRS for residual History: Surveillance. Abnormal smell and taste, vision blurriness, unsteady gait, memory problems. There is no evidence of acute ischemic or hemorrhagic lesion on this scan.Evidence of prior bifrontal craniotomy is seen.Encephalomalacia on bilateral rectus gyri (left more than right), left medial orbital gyrus and left anterior orbital gyrus are seen, no change since prior scan. In addition, bilateral inferior frontal gyri show increased signal intensity lesions on FLAIR indicating postoperative changes.There are relatively intense enhancements involving planum sphenoidale, bilateral cavernous sinus (right more than left), clivus and pituitary fossa which again do not show any significant interval change since prior scan. In particular there is asymmetric focal enhancement on the right posterior aspect of the clivus, again no change since prior scan. Scattered high signal intensity lesions on FLAIR on bilateral white matter are non-specific.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 paranasal sinuses and mastoid air cells are clear.
1. Post bilateral frontal craniotomy with associated postoperative changes as described above, no change since prior scan.2. No change of anterior cranial fossa, clivus and pituitary fossa enhancing lesions since prior scan.3. No evidence of acute ischemic or hemorrhagic lesion.
