| Discussion | Pituicytoma, granular cell tumor of the sellar region, and spindle cell oncocytoma (follow the WHO CNS5) Imaging findings There is a well-defined mass involving sellar and suprasellar region. The mass is isointense with brain on T1WI and hyperintense on T2WI. On dynamic contrast enhanced studies, it is clearly separate from anterior pituitary gland, which shows delayed enhancement. It shows fast and relatively homogeneous enhancement. Pituitary stalk is not well delineated. 고찰 Pituicytoma, granular cell tumor of sellar region, spindle cell oncocytoma are included in pituicyte tumor family. They arise from modified glial cells (pituicytes) that reside in the infundibular stalk and neurohypophysis. Radiographic features : CT - homogeneously enhancing mass - either within pituitary fossa or in the suprasellar region : MRI - intrasellar mass that is clearly separate from anterior pituitary gland and enhances homogeneously is most likely a pituicytoma - T1: isointense solid mass - T2: hyperintense - T1 C+ (Gd): homogeneous contrast enhancement |
