Presentation
Chronic headaches in a diabetic and hypertensive patient.
Patient Data
Well-defined broad-based extra-axial left temporal mass. It displays an isosignal to the cortical grey matter on T1, slightly high signal on T2 and FLAIR with vivid homogeneous enhancement with a "dural tail sign". No calcification or hemorrhagic component is seen on the GE sequence. A "CSF cleft sign" around the mass is noted on the coronal T2 sequence indicating its extra-axial location. No surrounding vasogenic edema or significant mass effect on the midline structures.
Cerebral volume loss with small vessel ischemic change is noted.
Case Discussion
MRI features most consistent with temporal meningioma.
