Male, 64 years old, history of meningioma. Surveillance scan. An enhancing extra-axial nodule, which projects superiorly from the junction of the right tentorium and transverse sinus, continues to measure 9 x 9 x 8 mm and shows no significant interval change since the prior exam. The transverse sinus remains patent based on preservation of the T2 flow void and contrast opacification.No new enhancing or nonenhancing intracranial lesions are demonstrated. A few scattered small foci of white matter T2 hyperintensity are again seen, similar to prior. No evidence of parenchymal edema or significant mass effect is seen. No intracranial hemorrhage or any abnormal extra-axial collections are seen. Mild prominence of the CSF space in the posterior fossa, and along the cerebral vertices, is stable and may reflect some degree of volume loss. The ventricular system is stable and normal in size.
Stable right occipital region extra-axial mass presumed to represent a meningioma.
