Pituicytoma. Sagittal T1WI image (A) and coronal T1WI postcontrast scan (B) show a rounded suprasellar mass that is clearly separate from the pituitary gland.

Spindle cell oncocytoma. Coronal T1WI (A) demonstrates a mixed intra- and suprasellar infiltrating pituitary lesion. Coronal T1-postcontrast scan (B) reveals a heterogeneous pattern of enhancement. Sagittal T1WI (C) shows enlargement of the anterior pituitary by the infiltrating mass and displacement of the unaffected neurohypophysis. (From Vajtai I, Sahli R, Kappeler A. Spindle cell oncocytoma of the adenohypophysis: report of a case with a 16-year follow-up. Pathol Res Pract 2006:202:745–50. Used with permission.)

Granular cell tumor. T1-weighted postcontrast scan (A) demonstrates a large suprasellar mass with a heterogeneous pattern of enhancement that is clearly separate from the pituitary gland. Contrast-enhanced axial CT (B) shows a large mass with heterogeneous enhancement that is hyperattenuated compared with brain. (From Buhl R, Hugo HH, Hempelmann RG et al.
