AbstractPituitary apoplexy is an uncommon but potentially life-threatening emergency due to abrupt ischemic infarction or hemorrhage of the pituitary tumor. In many instances, pituitary apoplexy is the initial presentation in patients who were not previously diagnosed to have pituitary adenomas. Variety of precipitating factors have been linked to the occurrence of pituitary apoplexy, which include pregnancy. However, pituitary apoplexy related to pregnancy is limited to isolated case reports and very small case series. The main symptom is headache of sudden onset associated with visual disturbances, signs of meningeal irritation, and/or endocrine dysfunction. In the context of pregnancy the diagnosis of pituitary apoplexy can be challenging and confused with other complex conditions such as pre-eclampsia. Magnetic resonance imaging is the most sensitive sequence to confirm the diagnosis by revealing a pituitary tumor with hemorrhagic and/or necrotic components. Corticotropic deficiency with adrenal insufficiency is a potentially life-threatening disorder for both mother and the fetus if left untreated. The choice between conservative management with dopamine agonists and glucocorticoid, this "wait and see approach" and trans-sphenoidal resection depend on the severity of neuro-ophtalmic signs and the gestational week. In this article, we present three cases of pituitary apoplexy related to pregnancy. Pituitary apoplexy occurred in the third trimester in the three cases. It was the first presentation of an unknown pituitary adenoma in two cases, and complicated a preexisting macroprolactinoma in the other case. All three cases of our patients had sudden onset of severe headache and deterioration of the visual field in two cases. The pituitary MRI performed in our patients was the essential tool confirming the diagnosis of pituitary apoplexy. In all the patients was prompt replacement of deficient hormones especially glucocorticoids with close surveillance. The trans-sphenoidal resection was indicated in two pregnant women; as the first choice treatment in one case presenting with papillary edema, and as the second line after the deterioration of the visual field in one case. In the lack of guidelines of management pituitary apoplexy in case of pregnancy, we review the existing literature with pertinent clinical presentation, radiological findings, management and maternal/fetal outcomes of this rare pathology. The aim is to provide a rational framework for therapeutic management of pituitary apoplexy during pregnancy.Copyright © 2019 Elsevier Masson SAS. All rights reserved.
