Benign neoplasm of cerebral meninges [225.2], Reason for Study: ^Reason: eval post-op tumor resection History: eval for residual tumor There is evidence of right frontal parietal craniotomy indicating postoperative status including overlying scalp swelling, minimal localized fluid collections and air.Previously seen right frontoparietal extra-axial (overlying on the central sulcus) has been removed with blood products on surgical bed. There is no evidence of enhancing lesion on the meninges, nor overlying skull especially inner table.Although due to subacute surgical bed blood products, minimally enhancing lesion which can suggest residual tumor cannot be excluded, there is no definitive evidence of residual tumor on the scan.Extensive parenchymal edema on the area of surgery is still seen.Minimal deformity of the right lateral ventricle due to mass effect is still seen, no change since prior scan. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Postoperative changes of right frontoparietal extra-axial mass with overlying skull inner table involvement including local surgical bed blood products, no MR evidence of residual tumor on neither meninges no overlying skull inner table.2. No change of local brain edema with mild effacement of right lateral ventricle.3. No evidence of acute ischemic lesion.
