Axial T2 (left) with a sagittal T1 image (right) demonstrate a large homogenous mass
obliterating the foramen magnum and displacing the medulla anteriorly. The mass is intermediate
in signal on both T1 and T2 images.
Post gad sagittal (left), coronal (middle) and axial (right) scans reveal homogenous enhancement
of the mass with a dural tail revealing its true extra axial extent. Also note the enlarged
pituitary gland (left image).
