咽頭腔外長期嵌在異物の一症例

Abstract

Clinical case report of a 61-year-old woman with retropharyngeal foreign body is presented. She noticed pharyngalgia just after eating a slice of mackerel. A neighbourhood otorhinolaryngologist prescribed medication, without pointed out the foreign body. Several days later, the pharyngalgia disappeared. Fifty days after eating mackerel, she began to complain of a lump sensation in the throat, and visited our hospital. On endoscopy, granulation was seen on the postpharyngeal wall, just above the right pyriform sinus. A cervical X-ray film revealed the foreign body in the retropharyngeal space. It could not be found by esophageal endoscopy and finally it was removed by a lateral neck incision. The foreign body was a fish bone and it had remained there for 88 days.
