Neurogenic pulmonary edema (NPE) is a potential complication of a central nervous system (CNS) insult such as intracranial hemorrhage, uncontrolled generalized seizures, head trauma, tumors, and neurosurgical procedures. The proposed etiology is massive sympathetic discharge following a CNS event. The pathogenesis is not completely understood. However, there are two theories on how NPE occurs: the blast theory and the permeability defect theory. There is evidence for both theories, and NPE is probably the result of a combination of the two. The treatment is mainly supportive with the use of mechanical ventilation and alphaadrenergic blocking agents while managing increased intracranial pressure. A thorough understanding of the pathophysiological mechanisms behind the development of NPE aids in the management of these patients to prevent further complications.
