  Fig. 1 A 39-year-old female with a pituitary abscess. A, B. Axial (A) and coronal (B) T1-weighted (500/10) images show a huge mass in the sellar and suprasellar area with mild compression of the optic chiasm (black arrow). The mass shows hyposignal intensity (white asterisk) with round hyperintense rim (white arrow). C. Coronal T2-weighted image (3000/80) shows high signal intensity mass (white asterisk) with a thin hypointense rim (white arrowheads). D. Sagittal contrast enhanced T1-weighted (500/10) image shows a rim-enhancing mass (white arrows).
