Neoplasm of uncertain behavior of cerebral meninges [D42.0], Reason for Study: ^Reason: L frontal atypical meningioma s/p resection and adjuvant radiation History: assess for extent of disease Redemonstration of the left frontal craniotomy with localized extra axial fluid collections, unchanged since prior scan.There is nodular and slightly linear enhancement at the surface of the left frontal lobe under the surgical resection site (series 1001, image 24/34) which likely represent postoperative changes or scar tissue, unchanged since prior scan.Scattered T2/FLAIR high signal intensity lesions on periventricular white matter indicating minimal non specific small vessel ischemic disease, unchanged.The ventricles, sulci and cisterns are unremarkable. There is no mass, mass effect, edema, midline shift, hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. 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.Mucosal thickenings on paranasal sinuses and retention cysts on bilateral maxillary sinuses are seen, slightly worse than prior.
1. No evidence of recurrence of previously resected tumor.2. No evidence of acute ischemic or hemorrhagic lesion.
