Figure 1: MRI images demonstrate basal meningitis and a pituitary adenoma. Preoperative MRI images demonstrate severe basal meningitis (asterisk) in T1W postcontrast image (a), and in FLAIR images (b). Inflammatory mass extends from the midline along the middle cerebral arteries bilaterally. Dedicated pituitary 3D SPGR postcontrast coronal (c) and sagittal (d) images demonstrate a hypoenhancing adenoma (white arrowhead) within the sella. T1W postcontrast (e) and FLAIR (f) images obtained 18 months following surgery demonstrate improving basal meningitis. 3D SPGR – volumetric spoiled gradient, FLAIR – fluid attenuated inversion recovery, MRI – magnetic resonance imaging, T1W – T1 weighted
