From the case:
Meningioma - frontal convexity
Loading images...
Axial T1
The MRI sequences demonstrate a well-circumscribed broad-based left frontal extra-axial mass (4 x 3.5 x 2.5 cm) with adjacent hyperostosis of the inner table of the skull. It shows an isosignal to the cortical grey matter on T1, T2, and FLAIR with areas of calcification of low signal on GE and mild surrounding vasogenic edema. The postcontrast sequences show intense and heterogeneous enhancement with dural tail sign well-visualized on coronal and sagittal sequences.
The extra-axial location is evidenced by a thin rim of "CSF cleft sign" around the mass on coronal T2.
Partially empty sella is noted
