L’œdème pulmonaire neurogénique : une entité souvent méconnue.

Neurogenic pulmonary edema (NPO) is a rare and underdiagnosed clinical entity, occurring within minutes to hours of central nervous system damage. The pathogenesis of NPO is not completely understood, systemic vasoconstriction, as a consequence of higher levels of catecholamines, associated to systemic inflammatory response lead to increase capillary permeability and result in pulmonary edema. Hypoxemic respiratory failure following a catastrophic neurological event, which cannot be attributed to other causes is the main characteristic of NPO. Management is essentially based on the control of the triggering neurologic condition in order to quell the sympathetic discharge. We report the case of female who presented hypoxemic respiratory distress following a subarachnoid hemorrhage. Clinical examination and radiological investigations led to the diagnosis of neurogenic pulmonary edema. [ABSTRACT FROM AUTHOR]
