Aspiration of sand and other foreign material is often discovered at autopsy in victims of drowning, but is not commonly seen radiographically. Two such cases are described, one of drowning and one of near drowning. In each case, the sand was radiopaque because of its calcium carbonate content and created a "sand bronchogram", i.e., sand in the tracheobronchial tree. With early recognition, successful bronchoscopic removal of the aspirated sand is possible.
在溺水受害者的尸检中，经常会发现沙子和其他异物的吸入，但在影像学上并不常见。本文描述了两例这样的病例，一例为溺水，一例为近乎溺水。在每例病例中，沙子因其碳酸钙含量而不透射线，并形成了“沙子支气管造影”，即在气管支气管树中发现沙子。如果能早期识别，通过支气管镜成功取出吸入的沙子是可行的。
