Non-endocrine pituitary tumors

Non-endocrine tumors of the sellar region can extend in all directions, and particularly supra sellar, where they are responsible for a chiasmatic syndrome plus or minus intracranial hypertension, or even neuropsychic disorders, which is why they are so serious and so difficult to manage.A distinction is made between tumors of the posthypophysis, known as pituicytomas, which develop from specialized glial cells of the posthypophysis, and dysgenetic tumors arising from remnants of the pharyngo-pituitary duct, such as craniopharyngiomas, histologically benign, but locally invasive, sellar or supra-sellar tumors [3], Rathke's pouch cysts, most often discovered on imaging, and non-dysgenetic tumors (meningiomas, chordomas, lipomas), are much rarer.In this booklet, intended for medical students, residents and specialists in Endocrinology, Pediatrics, Neurology, Neurosurgery, Oncology and Radiotherapy, we address the clinico-radiological and therapeutic aspects of non-endocrine pituitary tumors.
