Syndrome Jonctionnel Révélant un Macro Adénome Hypophysaire : À Propos d'un Cas: Junctional syndrome revealing pituitary macro adenoma: A Case Report

Abstract

Junctional syndrome is the 2nd most frequent chiasmatic lesion after bitemporal heminanopsia, and is most often secondary to tumoral and compressive causes. Pituitary adenoma is the main cause in adults. We report the case of a 41-year-old patient who came to us with a marked left eye decreased visual acuity evolving for 02 years, in whom ophthalmological examination revealed a left relative afferent pupillary deficit, sectorial papillary pallor and optic atrophy on the right and left respectively, in favor of bilateral optic neuropathy. The visual field revealed a right temporal hemianopia and left total blindness, indicating basic junctional syndrome, and the orbito-cerebral CT scan showed a pituitary macroadenoma. Pituitary adenoma is a frequent and serious pathology, affecting visual function and sometimes life. The ophthalmologist plays a decisive role in the diagnosis and follow-up of this condition
