Abstract
A case of a partially swallowed fish bone that migrated into the hypopharyngeal mucosa is reported. A 57-year-old female who had a pain after eating fish is presented. The migrated fish bone was easily detected in her hypopharyngeal mucosa, so that the fish bone was carefully removed. Eight days after removal, she had a sharp pain in her pharynx. A CT scan was performed immediately and the CT suggested that some of the fish bone remained in her hypopharyngeal mucosa. Subsequently, direct laryngoscopy with the patient under general anesthesia was performed and the remaining fish bone was extracted.
In many cases, impacted fish bones are readily detected and removed, so a radiological examination is not necessary to provide a diagnosis; however, a CT scan is useful to identify a migrated fish bone that cannot be seen directly.
