Known left temporal meningioma. Surveillance to rule out progression. The dural-based round extra-axial lesion overlying the left anterior temporal lobe which demonstrates a dural tail and intense homogeneous enhancement measures 11 x 13 x 14 mm. This measured 9 x 10 x 10 mm in similar dimension previously on the original exam, but demonstrates similar dimensions to the most recent comparison. There is unchanged minimal local mass effect on the adjacent superior temporal gyrus. There is focus of FLAIR hyperintensity in the left temporal lobe, which may represent edema and/or gliosis and stable to minimally increased from prior allowing for differences in technique.Scattered foci of high T2/FLAIR in periventricular and subcortical white matter are unchanged and compatible with mild chronic small vessel ischemic changes. There is unchanged focus of susceptibility in the right frontal lobe consistent with chronic microhemorrhage. There is no new intracranial mass, fluid collection, hemorrhage, hydrocephalus or ischemia. Normal flow-voids are demonstrated within major intracranial vessels. Incidental note is made of a stable right parietal DVA. Unchanged small osseous protuberance posterior to the right frontal sinus. Small fluid levels within the left sphenoid sinus, small right maxillary mucous retention cyst, and minimal left maxillary mucosal thickening are noted.
No significant change in size of small left anterior temporal meningioma compared to 10/22/2013. There is minimal interval enlargement when compared to earliest available study from 8/26/2010. Mild adjacent FLAIR hyperintensity in the left anterior superior temporal gyrus is stable to minimally increased and may represent minimal amount of edema and/or gliosis.
