Research Excerpts

Overview

ExcerptReference
"Idiopathic granulomatous hypophysitis is a rare inflammatory disease of the pituitary gland that can closely mimic a pituitary adenoma clinicoradiologically."( Larijani, B; Mohajeri-Tehrani, MR; Navabakhsh, B; Sharifi, G; Valeh, T, 2019)
"Autoimmune hypophysitis is a rare disease characterized by the infiltration of lymphocytic cells into the pituitary gland."( Cheng, X; Kong, Z; Ma, W; Wang, Y, 2020)
"Primary lymphocytic hypophysitis is an autoimmune disease characterized by lymphocytic infiltration of the pituitary gland, with a higher incidence during late pregnancy and the postpartum period."( Andreu, D; Reyes S, P; Toledo, C, 2020)
"Autoimmune hypophysitis is a rare condition that often results in enlargement of the pituitary gland and hypopituitarism due to inflammatory infiltration."( Andersen, MS; Glintborg, D; Kruse, M; Markovic, L; Olesen, TB, 2021)

Treatment

ExcerptReference
"Primary autoimmune hypophysitis (PAH) evolves in most untreated cases in irreversible hypopituitarism."( Angelini, F; Arena, V; Bianchi, A; Capoluongo, ED; Chiloiro, S; Colosimo, C; De Marinis, L; Giampietro, A; Pontecorvi, A; Tartaglione, T; Zoli, A, 2018)
