Female, 79 years old, history of left intraventricular and right frontal meningioma, surveillance imaging. An enhancing mass is redemonstrated within the trigone of the left lateral ventricle, unchanged in size when compared to multiple prior examinations and measuring approximately 32 x 29 mm in the axial plane.A small dural based enhancing lesion along the right frontal lobe is also unchanged in size measuring approximately 12 x 7 mm in the axial plane.Also stable is a subcentimeter enhancing lesion within the right parietal bone. No new enhancing parenchymal or extra-axial lesions are detected. No evidence of new parenchymal signal abnormality is seen. A few small scattered foci of white matter T2 hyperintensity are nonspecific and stable.No evidence of intracranial hemorrhage or any abnormal extra-axial fluid collection is seen. Allowing for tumor expansion of the left ventricular trigone and mild dilatation of the left temporal horn, the ventricular system is stable and otherwise unremarkable.
1.Stable presumed left intraventricular meningioma.2.Stable presumed right frontal meningioma.3.No new intracranial lesions.
