Two cases of fish-bone foreign body were reported. Case 1 was a 75-year-old female who suffered from cervical pains after eating bonito. No foreign bodies were found by indirect laryngoscopical nor esophagoscopical examination. The foreign body was found embedded in the posterior wall of the pharyx on X-ray and CT scan. Case 2 was a 77-year-old female who had pains after eating bonito. Neither indirect laryngoscopical nor esophagoscopical examination revealed any foreign bodies in the pharyngoesophageal space. X-ray and CT scan revealed an extra-esophageal foreign body with a surrounding periesophageal abscess and cervical subcutaneous emphysema. By an extra cervical incision, the foreign body was found penetrating the esophagus and reaching carotid artery. These two cases suggest the importance of conducting X-rays and CT scans even if no foreign bodies are found under laryngo-esophagoscopical examination.
