72-year-old female with an enlarging meningioma for operative planning. Redemonstrated is evidence of craniotomy at the parietal vertex. Nonspecific dural thickening and a small fluid collection subjacent to the craniotomy are stable.Tumor centered on the posterior interhemispheric falx in the parietal region is approximately unchanged in size relative to the most recent examination, with approximate dimensions of 60 x 30 mm in length and width. There is no evidence of contrast within the superior sagittal sinus at the level of the parasagittal meningioma, which is not significantly changed in the interval. Encephalomalacia and ill-defined T2 signal abnormality affecting the bilateral parietal lobes and the left occipital lobe are unchanged. Scattered small foci of T2 hyperintensity within the cerebral hemispheres and brainstem are also unchanged. No new lesions are detected. No new pathologic enhancement is identified. The ventricles are stable in size and morphology.Fluid signal in the right mastoid air cells and middle ear cavity is again demonstrated.
1. Limited evaluation for operative planning related to a parasagittal meningioma.2. Extensive post treatment changes in the brain are not significantly changed since 8/1/2016.
