Case Reports
Role of volume rendered 3-D computed tomography in conservative management of trauma-related thoracic injuries.
Pneumatic nail guns are a tool used commonly in the construction industry and are widely available. Accidental injuries from nail guns are common, and several cases of suicide using a nail gun have been reported. Computed tomographic (CT) imaging, together with echocardiography, has been shown to be the gold standard for investigation of these cases. ⋯ Volume-rendered CT of the thorax allowed an accurate assessment of the thoracic injuries sustained by this patient. As there was no evidence of any acute life-threatening injury, a sternotomy was avoided and the patient was observed closely until discharge. In conclusion, volume-rendered 3-dimensional CT can greatly help in the decision to avoid an unnecessary sternotomy in patients with a thoracic nail gun injury.

Diffuse dendriform pulmonary ossification is a rare disorder characterized by widespread pulmonary ossification distributed in a characteristic branching pattern. It is usually associated with chronic interstitial inflammation and fibrosis but may occasionally be idiopathic. ⋯ Computed tomography findings characteristically show fine branching heterotopic bone formation within the lungs, often in a lower lobe distribution. A case of idiopathic dendriform ossification is described in a 34-year-old man who presented for investigation of hemoptysis.
