 Again seen are postsurgical changes of right frontotemporal craniotomy for resection of sphenoid wing meningioma. Again seen is minimal dural based thickening in the right middle cranial fossa measuring up to 7 mm in thickness extending medially into the right paraclinoid region, which is similar to prior from 2/3/2015. There has been evolution of previously seen immediate post surgical changes with resolution of previous seen parenchymal edema and associated mass effect. There has been interval development of encephalomalacia involving the right anterior temporal lobe. No evidence of mass effect on the current study. Remainder of the brain parenchyma appears unremarkable. No hydrocephalus. No extra-axial collections. Aside from aforementioned postsurgical changes, calvarium and extracranial soft tissues are unremarkable.
Compared to 2/3/2015, there is evolution of postsurgical changes related to prior right sphenoid wing meningioma resection with resolution of previously seen edema and associated mass effect and development of encephalomalacia in the right anterior temporal lobe. There is minimal dural based thickening and enhancement measuring approximately 7 mm in thickness in the right middle cranial fossa extending medially into the right paraclinoid region, which is suspected to represent minimal residual meningioma and remains unchanged since prior. No evidence of mass effect on the current study.
