 Again seen are postsurgical changes of right frontotemporal craniotomy for resection of sphenoid wing meningioma. Again seen is dural based thickening in the right middle cranial fossa measuring 7 to 8 mm in thickness, extending medially into the right paraclinoid region, and abutting the superior and inferior orbital fissures as well as the foramen rotundum on the right. The lesion demonstrates mild gradual enlargement especially when compared to 2/3/2015. In its medial aspect, the lesion measures 8x11 mm in the AP and CC dimension, 4 mm x 10 mm in this location on study from 2/3/2015.Again seen is encephalomalacia involving the right anterior temporal lobe similar to prior as well as a tiny focus involving the right anterior frontal lobe which is likely postsurgical. 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 and 9/9/2015, there is mild gradual enlargement of the previously seen residual meningioma in the right middle cranial fossa extending into the paraclinoid region, particularly in its medial aspect.
