Info
Well-defined lobulated extra-axial sellar and suprasellar mass centred on the tuberculum sellae. It displays an isosignal to the cortical grey matter on T1 and T2 with a homogeneous enhancement on postcontrast sequences. The suprasellar component compresses the optic chiasma and encases partially the supraclinoid segment of both ICA (mainly on the left) which show reduced calibre on the MRA.
The pituitary gland is well-visualised on enhanced sagittal and coronal T1 sequences.
Case Discussion
MRI features most consistent with a tuberculum sellae meningioma compressing the optic chiasma.
