Delayed Diagnosis of Pulmonary Artery Injury, Due to Blunt Trauma, which Mimicked Traumatic Lung Pseudocyst

ABSTRACT

A 67-year-old female presented to the emergency department with complaints of dyspnea and chest wall pain after a fall from a cultivator. Initial chest CT showed multiple left rib fractures, a loculated hematoma without active bleeding, and hemothorax. On the third day of admission, the chest X-ray showed an abrupt aggravation of haziness and the chest CT showed that the size of the hematoma had increased with active bleeding from the pulmonary artery. In cases of loculated hematomas adjacent to the hilum on CT scan, the diagnosis of pulmonary artery injury should be considered.
