The chest radiograph of a 79-year-old man with acute thoracic aortic rupture demonstrated enlarged, ill-defined bronchovascular markings. Examination of the lungs at autopsy revealed extensive dissection of blood from the mediastinum along the bronchovascular sheaths. Recognition that enlarged bronchovascular markings may represent hemorrhage rather than edema in the setting of acute aortic rupture has important therapeutic implications.

Acute pancreatitis developed in a child following inadvertent placement of a gastrostomy tube balloon in the descending duodenum. After a gastrostomy tube is inserted, radiologic confirmation of correct tube position is recommended to help avoid this rare iatrogenic complication.
