Diagnosis: Benign neoplasm of cerebral meningesClinical question: h/o meningioma s/p resection in 2012Signs and Symptoms: surveillance The CSF spaces are appropriate for the patient's stated age with no midline shift. The patient is status-post right-sided craniotomy for removal of an extra-axial mass adjacent to the right frontal lobe. Although there is a minor dural thickening present at the craniotomy site this remains stable when compared to the prior exam. There is redemonstration of some minor signal changes within the brain parenchyma adjacent to the prior tumor bed which also remained stable since previous exams but have regressed since the preoperative exam.There are several subcortical punctate white matter lesions which are high signal on T2 and FLAIR MR present which are unchanged since the prior exam.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Stable exam without evidence for tumor recurrence. Some residual dural thickening at the prior tumor bed may represent post treatment change and is stable.
