    INPUT: The heart is normal in size . There is mild elevation of the left hemidiaphragm with streaky opacity suggesting atelectasis and volume loss . There is no pleural effusion or pneumothorax .

Projecting over the left upper quadrant , probably along the gastric cardia is a linear radiodense foreign body measuring about 2 .5 cm in length but only up to 3 mm in width .
