Clinical question: Tumor growth. Signs and symptoms: Falcine meningioma. Pre and post enhanced brain MRI:Examination demonstrates a right parafalcine posterior parietal dural based enhancing meningioma measuring at 33 x 14 mm coronal post enhanced series and approximately 22.5 x 14 mm in transaxial dimensions. Compared to prior exam there is no evidence of any appreciable interval change in the size, extent or uniform pattern of enhancement of the tumor.There is subtle buckling of the adjacent right parietal lobe similar to prior exam. There is revisualization of extensive cystic encephalomalacia of the left posterior parietal without interval change.Stable broad-based shallow right parietal parafalcine T1 hypointense finding representing pulsing calcification. An additional smaller similar finding in the left anterior frontal parafalcine region without interval change is also again noted.Images through posterior fossa demonstrate prominence of cerebellar and vermian folia for stated age of 43 however without change since prior exam. Unremarkable and stable study otherwise.Note from radiology resident on call indicates patient developed hives after injection of contrast which was treated with 50 mg of Benadryl and was discharged without complications.
1.No evidence of an acute or new finding since prior study.2.Stable right parafalcine posterior parietal meningioma as detailed.3.Stable falcine calcification in the right parietal and left anterior frontal similar to prior exam.4.Prominence of cerebellar and vermin folia for stated age of 43 without change since prior exam.5.Unremarkable and stable pre- and post enhanced brain MRI otherwise.
