Case contributed by A.Prof Frank Gaillard

Presentation

Admitted to ICU with necrotising fasciitis, septic shock and acute renal failure. Progressive respiratory failure requiring ventilation.

Patient Data

Age: 65
Gender: Male
Modality: X-ray

Multifocal bilateral air-space opacities, in a predominantly perihilar and lower zone distribution. 

Case Discussion

This is a characteristic appearance of ARDS in the appropriate clinical context.

The differential diagnosis includes infection (also a common complication of ARDS), and cardiogenic pulmonary oedema. Differentiation can be impossible in some cases.

The causes of ARDS include:

  • trauma
  • septicaemia
  • hypovolaemic shock
  • fat embolism
  • near-drowning
  • burns
  • viral pneumonia
  • pancreatitis
  • oxygen toxicity
  • disseminated intravascular coagulopathy

ARDS mortality is high, around 50%, and many survivors develop chronic lung disease, with damaged lung healing by fibrosis. A minority recover fully.
