Meningioma resection: surveillance. There has been interval evolution of postoperative findings related to resection of a right middle cranial fossa meningioma. There is a small amount of plaque-like enhancement along the floor of the middle cranial fossa in the operative bed, measuring up to 3 mm in thickness. Otherwise, there is interval resolution of vasogenic edema in the right anterior temporal lobe, with a small area of encephalomalacia in the surgical bed region. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. There is a small, branching developmental venous anomaly within the left paramedian pons. The major cerebral artery flow voids are intact. The orbits are grossly unremarkable.
