“…This rare condition (3% of patient with PA) associates sudden headache, confusion, visual troubles such as chiasmatic syndrome or oculomotor paralysis, and acute endocrine disturbances up to panhypopituitarism. 2 Substitutive hormonotherapy and surgical resection have highly favorable outcome with in particular a good visual recovery, as in our patient. The normal pituitary gland is usually not clearly distinguishable from the surrounding background 3 on 18 F-FDG PET/CT due to its small size and low metabolic activity, whereas pituitary tumors have higher energy consumption.…”

We report the case of 69-year-old man referred for a stage IV pulmonary adenocarcinoma and presenting a decrease in visual acuity. An 18F-FDG PET/CT showed an intense and heterogeneous uptake of a mass in the sellar region. An MRI showed a pituitary macroadenoma associated with a large cyst on the left side, with necrosis zones and fluid level, compressing the optic chiasma. Endocrine testing showed a panhypopituitarism, and pathology confirmed a pituitary apoplexy in a gonadotropin-secreting macroadenoma. No malignant cells were detected. Molecular imaging could have an important role in the detection and characterization of pituitary tumors.

“…The neuroophthalmological picture in pituitary apoplexy is characterized by a sudden reduction or loss of vision, sometimes with acute temporal hemianopia in the presence of marked headache. CN III, CN IV and/or CN VI lesions resulting in ptosis, mydriasis and limitation of the eye movements may occur if the neoplasm is located close to the site of the cavernous sinus [24,25].…”

This article reviews the causes, pathogenesis, and major manifestations of chiasmal syndrome. In addition, it reviews the methods for diagnosing the condition, and the course of the syndrome in patients with various chiasmal-and-sellar disorders such as pituitary adenoma, craniopharyngioma, tuberculum sellae meningioma, and skull base aneurysm. The principle neuro-ophthalmological symptoms include decreased visual acuity, bitemporal visual field defects, and development of descending optic nerve atrophy. Early detection of ophthalmological symptoms is of critical importance for timely neurosurgical treatment.

“…En effet, par exemple pour le suivi d'une tumeur de l'hypophyse, on préfère effectuer une IRM associée, à des rythmes variables, à des relevés de champs visuels par périmétrie automatisée (24 ou 30 degrés), à la place d'enregistrement des PEV [Pakzaban et al, 2000], [Baglin et al, 2009].…”
