Benign neoplasm of meninges, unspecified [D32.9], Reason for Study: ^Reason: grade I meningioma. History: meningioma. Right fronto-parieto temporo-occipital craniectomy extended toward left side across the midline as well as bilateral suboccipital craniectomy are seen, unchanged.Associated encephalomalacia involving right temporal, right occipital, left parietal, left occipital and bilateral cerebellar hemisphere are seen, unchanged.T2 intermediate and T1 iso signal intensity lesions on the right petromastoid area which compresses right inferior temporal lobe is again seen, unchanged in terms of maximum diameter, MR signal intensities and extent of mass effects and edema. The ventricles, sulci and cisterns are unremarkable. There is no evidence of acute ischemic or hemorrhagic lesion. The paranasal sinuses and mastoid air cells are clear.
1. Post craniectomy status with residual mass on the right petromastoid region, unchanged in terms of the size of residual mass and mass effects against right temporal lobe since prior scan.2. No evidence of acute ischemic or hemorrhagic lesion.
