    INPUT: Patchy , possibly calcified , opacity projecting over the left mid hemi thorax may relate to pleural calcification versus pneumonia . No prior available for comparison . Chest CT would further assess . No pleural effusion or pneumothorax is seen . The cardiac and mediastinal silhouettes are unremarkable . Increased sclerosis at the bilateral humeral heads , not well assessed , but concerning for osteonecrosis / bone infarcts . Some H - shaped vertebra are seen , related to sickle cell .
    OUTPUT:
    
Patchy , possibly calcified opacity projecting over the left mid hemi thorax may be pleural in origin and possibly pleural calcification versus pneumonia . Chest CT would further assess . Sclerosis at the partially imaged humeral heads raise concern for underlying bone infarct / osteonecrosis .
