66-year-old female with headaches and a known meningioma. Evaluate meningioma size.Further history from electronic medical record: History of breast cancer. There is no evidence of intracranial hemorrhage or acute infarct. There is no signal abnormality within the brain parenchyma. Along the superior sagittal sinus overlying the right parietal lobe there is a 16 x 16 mm extra-axial lesion which is heterogeneous on T1 and T2 weighted images, dark on susceptibility weighted images, and heterogeneously enhancing. There is no surrounding edema. The adjacent sagittal sinus is thinned but enhances suggesting maintenance of flow. There is no abnormal enhancement elsewhere. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. Status post right lens replacement. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
16 x 16 mm extra-axial lesion along the right parietal lobe adjacent to the superior sagittal sinus compatible with meningioma.
