BACKGROUND AND PURPOSE: Pituicytoma, SCO, and GCT are poorly understood entities
with confusing nomenclature and undetermined imaging characteristics. Our purpose was to …

Abstract In 2017, the World Health Organization established that pituicytoma, granular cell
tumor (GCT), spindle cell oncocytoma (SCO) and sellar ependymomas (SE) are posterior …

The 4th edition of the WHO Classification of Tumours of the Nervous System (WHO 2007)
introduces changes that reflect both the recognition of new brain tumour types and a better …

Purpose Pituicytomas and spindle cell oncocytomas (SCOs) are extremely rare neoplasms
of the sellar and suprasellar region that can often mimic pituitary adenomas. To date, there …

Pituicytoma is a rare tumor of the sellar and suprasellar regions, arising from the pituicytes,
which are specialized glial cells in the neurohypophysis and infundibulum. Due to its rarity …

While pituitary adenomas make up over 90% of all sellar masses, there are a number of less
known tumors, both malignant and benign, which may arise within the sella turcica. These …

Sellar masses are associated most commonly with pituitary adenomas. Many other
neoplastic, inflammatory, infectious, and vascular lesions, however, may affect the sellar …

Abstract Background Pituicytomas (PTs) are extremely rare, low-grade glial tumors closely
related to the neurohypophyseal axis. Definite conclusions concerning the optimal …

Objective Pituicytomas are rare neoplasms that typically present as solid, noninfiltrative
tumors occupying the sella and/or suprasellar space for which there is no consensus on …

Background: Spindle cell oncocytoma (SCO) and pituicytoma are rare nonfunctioning
tumors of the pituitary. Both tumors are low grade and macroscopically indistinguishable …
