Headache [R51] / Viral meningitis, unspecified [A87.9], Reason for Study: ^Reason: please r/o structural abnormality vs infiltrate History: Headache Redemonstration of relatively homogeneously enhancing dural based lesion indicating meningioma likely representing en plaque type. The lesion involves sella, bilateral cavernous sinus, Meckel's caves and retroclival region. Diffuse dural enhancements along bilateral tentorium are also seen. These findings do not show any significant interval change especially in terms of thickness and configuration since prior scan.There is a right frontal burr hole with underlying frontal lobe focal encephalomalacia, no change since prior scan.The ventricles, sulci and cisterns are symmetric and unremarkable. There is 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 paranasal sinuses and mastoid air cells are clear.
1. No significant interval change of skull base en plaque type meningioma in terms of its extent, estimated size and enhancement pattern since prior scan.2. No acute ischemic or hemorrhagic lesion.3. No change of right frontal burr hole and underlying brain biopsy track related parenchymal changes since prior scan.
