Objective: To evaluate and understand the clinical behavior and radiologic correlates of tumors originating from the posterior pituitary gland. To review the management strategy for these rare tumors and add to the limited existing literature.

2020年2月1日 · Pituicytoma, spindle cell oncocytoma, and granular cell tumor (GCT) of the sellar region are distinct, rare tumors of the neurohypophysis. They are considered as grade I in the 2016 World Health Organization (WHO) classification of tumors of the central nervous system.

Granular cell tumors (GCTs) of the neurohypophysis are rare tumors seen in the sellar and suprasellar region that are poorly understood because of the confusion regarding their nomenclature and indeterminate imaging features.

2019年11月15日 · Granular cell tumors (GCTs) of the neurohypophysis are parasellar tumors arising from pituicytes in the neurohypophysis and are generally considered benign slow-growing tumors. We present a case of sellar GCT with aggressive features.

2017年3月3日 · Granular cell tumor (GCT) of neurohypophysis was first reported by Boyce and Beadles in 1983. In 2016 WHO classification of central nervous system (CNS) tumors, GCT of neurohypophysis was defined as a distinct diagnosis. Here, we reported two cases of GCT of neurohypophysis misdiagnosed as pituitary adenoma and craniopharyngioma.

Granular cell tumor (GCT) of the pituitary is a rare benign tumor arising from the pituicytes of the neurohypophysis. These are the most common benign tumors of the neurohypophysis. These tumors are characterized by their slow growth and present usually with the visual symptoms due to compression of the optic chiasm. [1]

2011年12月1日 · The 2007 WHO Classification of Tumors of the Central Nervous System clarified and redefined criteria for pituicytoma, codifying it as a separate diagnostic entity distinct from GCT of the neurohypophysis. 1 The 2007 update also added a new entity—SCO—to the spectrum of nonadenomatous sellar neoplasms. 2 The purpose of our study was to apply ...

In this case, we present a 50-year-old patient with a sellar and suprasellar granular cell tumor of the neurohypophysis, who reported headaches, blurred vision and unsteady gait.

Background: Granular cell tumors (GCTs) of the neurohypophysis are rare neoplastic diseases of the pituitary. Because of the rare nature of the disease, previous descriptions have been limited to single-case studies, small series, or simple reviews.

2020年2月1日 · Pituicytoma, spindle cell oncocytoma, and granular cell tumor (GCT) of the sellar region are distinct, rare tumors of the neurohypophysis. They are considered as grade I in the 2016 World Health Organization (WHO) classification of tumors of the central nervous system.
