Level I

Chest computed tomography (CCT) is used to screen for injuries in hemodynamically stable patients with penetrating injury. We aim to determine the incidence of missed injuries detected on CCT after a negative chest radiograph (CXR) in patients with thoracic stab wounds. A 10-year retrospective review of a Level I trauma center registry was performed on patients with thoracic stab wounds. Patients who were hemodynamically unstable or did not undergo both CXR and CCT were excluded. Patients with a negative CXR were evaluated to determine if additional findings were diagnosed on CCT. Of 386 patients with stab wounds to the chest, 154 (40%) underwent both CXR and CCT. One hundred and fifteen (75%) had a negative screening CXR. CCT identified injuries in 42 patients (37%) that were not seen on CXR. Pneumothorax and/or hemothorax occurred in 40 patients (35%), of which 14 patients underwent tube thoracostomy. Two patients had hemopericardium on CCT and both required operative intervention. Greater than one-third of patients with a normal screening CXR were found to have abnormalities on CCT. Future studies comparing repeat CXR to CCT are required to further define the optimal diagnostic strategy in patients with stab wounds to chest after normal screening CXR.

Immunodeficiency Syndrome

Computed tomography of the chest was performed on 42 occasions as part of the diagnostic work-up in 26 homosexual men with, or suspected of the acquired immunodeficiency syndrome (AIDS). In 17 cases both the chest radiographs and the lung scans were abnormal, and bronchoscopy and/or lung biopsy established an etiologic diagnosis in the majority of these cases. In 9 cases CT of the lungs revealed unequivocal interstitial infiltration in the presence of a normal chest radiograph, and subsequently an etiologic agent was demonstrated in all these cases. In 9 cases, patients with symptoms indicative of pulmonary infection had both a normal chest radiograph and a normal lung scan, and in none of these cases did the clinical course or additional diagnostic procedures indicate the presence of current opportunistic lung infection. CT of the lungs seems to identify accurately those patients with severe HIV-related diseases in whom invasive diagnostic procedures such as bronchoalveolar lavage and/or lung biospy should be done.

Pulmonary cement embolism (PCE) is one of several complications of percutaneous vertebroplasty and kyphoplasty. Generally, PCE can be easily diagnosed based on typical chest radiograph findings such as single or multiple radiographically dense opacities with a tubular or branch shape in the lung field along with a recent history of percutaneous vertebroplasty or kyphoplasty. These findings can be alarming and may be encountered on routine chest radiographs, even in asymptomatic patients. One study showed that PCEs that were not visualized on chest radiograph were also not shown on chest computed tomography. However, we encountered a patient with dyspnea who had normal chest radiograph findings but was diagnosed with PCE through only the bone window setting on chest computed tomography. The present case will be beneficial to all physicians examining older patients with dyspnea.
