Meningioma - Solitary Parietal - Case 1

A 76 year-old woman presented with left occipital headaches.

Note the Isointense Tumor on T1          Note the Gadolinium Enhancement

MRI Scans (Left Upper) T1 axial; (Right Upper) T1 axial with gadolinium; (Bottom left) Parasagittal with gadolinium; (Bottom right) Coronal with gadolinium.  Note the large, well demarcated mass which is dural based and compressing the adjacent parietal lobe.  The mass is isodense on T1 but strongly enhances with contrast.  This is the typical appearance of a meningioma.  Meningiomas are common tumors.  They are typically benign histologically, and treatable with surgical resection if they are in an accessible location.
