An altered state of consciousness while using anticoagulants and the incidental discovery of a pituitary lesion: considering pituitary apoplexy.

Pituitary apoplexy (PA) is a medical emergency that can result in haemodynamic instability and abnormalities in the level of consciousness. The management of PA requires a multidisciplinary team that includes endocrinologists, ophthalmologists, neuro-radiologists, and neuro-surgeons. Pituitary MRI with gadolinium is the diagnostic gold standard for PA. PA therapy aims to improve general conditions and treat compression symptoms, especially visual field abnormalities. Adrenocorticotrophic hormone deficiency is a common and severe complication of PA. Thus, all patients with PA must be promptly treated with injective synthetic glucocorticoids (e.g. hydrocortisone 100 mg) and i.v. saline. PA must be taken into consideration in case of sudden headache in patients with a pituitary macroadenoma, especially if other risk factors are recognized.
