Benign neoplasm of meninges, unspecified [D32.9], Reason for Study: ^Reason: Eval for clival/sphenoid meningioma History: H/O meningioma followed by scans, eval for change/growth No evidence of acute ischemic or hemorrhagic lesion.Minimal nonspecific small vessel ischemic disease, unchanged.Diffuse dural thickening and enhancement along the clivus extends along bilateral prepontine cistern indicating possible meningioma are redemonstrated, unchanged.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. 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. Right maxillary sinus retention cyst is seen.
Unchanged dural thickening and enhancement at clivus and bilateral petrous apex areas indicating meningioma since prior scan.No acute ischemic or hemorrhagic lesion.No other abnormal enhancement.
