In a patient with ARDS (Acute Respiratory Distress Syndrome), what radiographic finding is typically seen in the later stages of the disease?
Explanation & Rationale
A. Pleural effusion: Pleural effusion is fluid accumulation in the pleural space and is not a typical finding in ARDS. It may occur secondarily, but it is not the hallmark radiographic feature. B. Ground glass appearance followed by white patches (white out): ARDS is characterized by diffuse alveolar damage. Early stages show ground-glass opacities on imaging, progressing to bilateral “white-out” or diffuse infiltrates in later stages due to alveolar flooding and fibrosis. C. Consolidation of the upper lobes only: ARDS affects both lungs diffusely and is not limited to any specific lobe. Upper lobe consolidation may indicate other conditions like tuberculosis or pneumonia. D. Honeycombing pattern: Honeycombing is typically seen in chronic interstitial lung diseases like idiopathic pulmonary fibrosis, not ARDS.
