54-year-old woman with history of meningioma. Postsurgical changes of a subtotal resection of sellar and suprasellar meningioma are again seen. Again seen is an avidly enhancing lesion in the pituitary fossa which extends along the planum sphenoidale and posteriorly along the clivus into the interpeduncular and prepontine cisterns. This lesion also surrounds the supraclinoid internal carotid arteries, right greater than left. The optic chiasm is indistinguishable from and surrounded by this lesion. This lesion has not changed in size compared with most recent as well as MRI examination on 11/17/2014. There is no new mass effect on the adjacent brain. There are postsurgical changes of prior bifrontal craniotomy with encephalomalacia and increased subcortical T2/FLAIR signal in the bilateral anterior and inferior frontal lobes.Additional, scattered foci of T2/FLAIR hyperintensity in the bilateral subcortical and periventricular white matter is nonspecific but compatible with small vessel ischemic disease. There is no restricted diffusion to suggest acute ischemia. There is no intracranial hemorrhage. The ventricles are within normal limits in size and configuration. The major flow-voids are preserved. There is mucosal thickening with atelectasis of the left maxillary sinus, stable from prior examinations and compatible with chronic sinusitis.
Stable appearance of the residual meningioma and posttreatment changes.
