An interesting cause of recurrent haemoptysis: haemoptysis 7 years after a foreign body penetrated the lung parenchyma and aorta.

ABSTRACT

A 43-year-old man presented with a 12-month history of recurrent haemoptysis. Postero-anterior chest X-ray of a patient with a history of a penetrating thoracic trauma 8 years previously showed a long wedge-shaped opacity just above the left hemidiaphragm, representing the 'tip of the knife' appearance, and penetrating from the lateral chest wall deep to the thoracic aorta. After consultation with the cardiovascular surgeons, it was decided that the patient should have an operation to remove the foreign body penetrating the aorta. During the operation, a piece of glass was located in the posterior segment of the left lower lobe, and it had also penetrated the aorta through to the posterior wall. The glass had a pointed end, was wedge-shaped and measured 8 cm x 3 cm x 0.5 cm. It was removed, and a 5-cm segment of aorta was replaced with dacron graft. Patients with penetrating chest trauma require routine chest X-rays as many will have a haemothorax, pneumothorax or a penetrating foreign body in the chest in the absence of clinical findings. Postero-anterior chest X-rays as well as lateral X-rays must be carefully and systematically examined for foreign bodies.
