Neurogenic pulmonary edema is an etiological subtype of non-cardiogenic pulmonary edema.
The diagnosis of neurogenic pulmonary edema is based on the occurrence of edema after a neurologic event/insult and the exclusion of other plausible causes.
It characteristically presents within minutes to hours following a neurologic insult and usually resolves within 72 hours.
The exact pathophysiology of is unclear, but it thought to relate to an adrenergic response leading to increased pulmonary hydrostatic pressure and increased lung capillary permeability 2.
On chest radiographs, there are nonspecific, bilateral, rather homogeneous airspace consolidative appearances with an apical predominance is thought to the present in about half of cases 4.
