Foreign bodies in the hypopharynx and cervical esophagus, such as chicken and fish bones, occur frequently and usually need radiologic work-up in order to demonstrate the presence of the foreign body and its location. Plain antero-posterior and lateral X-ray views of the neck, and if needed, a barium swallow, are the standard. When these studies fail to show the foreign body, unenhanced CT may demonstrate these small calcified esophageal foreign bodies. We evaluated 13 patients with cervical esophageal foreign bodies by CT. It is readily available and rapid and exposes the patient to less radiation than a barium swallow. CT evaluation with soft tissue and bone windows may replace the barium swallow because of its better detection of thin, small, minimally calcified foreign bodies which are often obscured by overlying tissues in the usual X-ray studies.
下咽和颈段食管异物，如鸡骨和鱼骨，较为常见，通常需要进行影像学检查以明确异物的存在及其位置。颈部正侧位X线平片，必要时行吞钡检查，是标准的检查方法。当这些检查未能显示异物时，平扫CT可能会发现这些小的钙化性食管异物。我们对13例颈段食管异物患者进行了CT评估。CT检查方便快捷，与吞钡检查相比，患者所受辐射剂量更小。由于CT软组织窗和骨窗检查对细小、轻微钙化的异物检测效果更好，而这些异物在常规X线检查中常被覆盖组织遮挡，因此CT评估可能会取代吞钡检查。
