An 18-year-old youth presented to the Emergency Department (ED) complaining of a BB in his right knee. He had been at a party the previous evening where some youths shot him. Examination revealed two small holes over the right knee; palpation suggested foreign bodies. He also complained of chest pain, giving a history of asthma. Physical examination revealed some tiny (l–2 mm) red marks over the anterior chest. There were a few wheezes but otherwise normal breath sounds. The heart sounds were normal and he had no jugular venous distention. The right knee had an entrance wound, below which there was a palpable small hard lump. There was an abrasion on the right elbow, but no entrance or exit wounds. Neurovascular examination was intact. Chest X-ray studies revealed metallic linear structures— two in the right middle lobe and one in the superior mediastinum (Figure l, A and B, arrows). No pneumothorax was present. There also appeared to be one in the infradiaphragmatic region. A computed tomography (CT) scan showed a straight pin above the aortic arch between the origin of the left carotid and left subclavian artery against the esophagus. The pin had its tip in a disk of the thoracic spine (Figure 2, arrow). Also, a pin can be seen near the region of the spleen on the lower cuts of the CT scan.
