What are possible differentials for this imaging pattern?
Diffuse pulmonary haemorrhage (Goodpasture's syndrome, Wegner's granulomatosis, systemic lupus erythematosus, Behçet's syndrome, bleeding diatheses, among others); infection (atypical, such as PCP, influenza), and non-cardiogenic pulmonary oedema.
There is widespread lung consolidation permeated by groundglass areas in keeping with alveoli obliteration. The pleural spaces are clear. A few prominent mediastinal lymph nodes are nonspecific.
