Neurogenic pulmonary oedema

This is a computed tomography scan of the lungs of a previously fit and well person in their 60s (fig 1). The patient presented with a one day history of breathlessness, cough, and dizziness. Bilateral crepitations were audible on auscultation, and nuchal rigidity was present. Inflammatory markers were within normal limits, including white blood cell count and neutrophil count: 11.35 (range 4-10×109/L) and 10.14×109/L (range 2-7×109/L), respectively. Bilateral shadowing suggestive of pulmonary oedema was detected on computed tomography of the chest. No cardiomegaly or pleural effusion was present. A computed tomography scan of the brain showed a subarachnoid haemorrhage from rupture of a left middle cerebral artery aneurysm.bmj;379/nov24_6/e069370/F1F1f1Fig 1Neurogenic pulmonary oedema was diagnosed, which can be due to a range of intracranial factors, such as traumatic brain injury, cerebrovascular events, or brain tumours.1 The pulmonary oedema resolved within five days after embolisation of the cerebral aneurysm.
