Neurogenic pulmonary oedema is an aetiological subtype of non cardiogenic pulmonary oedema.
The diagnosis of neurogenic pulmonary oedema is based on the occurrence of the oedema after a neurologic event/insult and on 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 generally 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.
