Female, 77 years old, history of meningioma, resection in 2013 Again seen is sequelae of a right suboccipital craniotomy for right posterior fossa tumor resection. The resection cavity is unchanged in size and morphology. T2 hyperintensity within the surrounding cerebellar parenchyma, likely representing gliosis, is also unchanged. No suspicious enhancement is seen within or around the resection cavity to suggest recurrent tumor.Minimal scattered foci of cerebral white matter T2 hyperintensity are again seen, unchanged. No restricted diffusion is evident. No mass effect or parenchymal edema is noted.Post contrast images are within normal limits. No evidence of acute intracranial hemorrhage or any new pathologic fluid collections are detected. Small foci of susceptibility within the frontal lobes likely represent chronic microhemorrhage is unchanged. The ventricles are stable and normal in size.There is diminished flow-void involving the right vertebral artery which may represent high-grade stenosis and seen previously.There is a left paramedian disc protrusion at the C2-C3 level which demonstrates mild mass effect on the left hemicord and grossly similar to prior cervical spine MRI from 7/17/2015.
Postoperative changes related to right posterior fossa meningioma resection. No evidence of recurrent tumor.
