CT scan of a patient with acute chest syndrome. A 53-year-old woman with sickle cell disease presented to the emergency department, complaining of pain typical of prior vaso-occlusive pain crises. A CT angiogram obtained on presentation to the emergency department revealed no infiltrate (left); however, extensive bilateral basilar airspace consolidations with small bilateral pleural effusions had developed on a repeat CT angiogram on day 3 (right).
