Female, 41 years old, status post meningioma resection in 3/2014. Yearly surveillance, on antiseizure medications. Postoperative changes related to resection of large left frontotemporal meningioma is again seen without appreciable change in appearance of the resection cavity and small areas of encephalomalacia in the left frontal and temporal lobes. Again seen is linear dural thickening and enhancement in the left middle cranial fossa abutting the greater wing sphenoid wing and extending medially to the level of the superior orbital fissure and inferiorly to the foramen rotundum. The thickening measures approximately 6 mm, previously approximately 5 mm. The left greater sphenoid wing remains expanded with minimal medial bowing of the lateral orbital wall. No mass effect on the optic nerve at the optic canal. No abnormal signal in the optic nerve or intraorbital extension of the tumor.Chronic blood products are present in the surgical bed. Elsewhere, brain parenchymal morphology is unremarkable. No new pathologic enhancement is seen. No evidence of acute ischemia or hemorrhage. Ventricles are stable and normal in size. Major vascular structures remain patent.
Postoperative changes related to resection of a large left frontotemporal meningioma are again seen. Compared to 1/19/2015, there is stable to perhaps minimal interval increase in thickness of the enhancing rind of tissue in the left middle cranial fossa which abuts the left greater sphenoid wing and extends medially to the level of the superior orbital fissure. This tissue measures 6 mm in thickness, previously 5 mm, and is suspected to represent minimal residual tumor. Optic canal remains patent.
