咽喉頭異常感を訴えたForestier病の1例

Forestier disease presenting with throat discomfort：A case report

I．はじめに

　咽喉頭異常感は日常臨床でしばしば遭遇する訴えの1つである。原因はきわめて多彩である^1）が，頸椎病変が原因となることも念頭に置く必要があるとされる^2）。今回われわれは，頸椎前面に巨大な異常化骨増殖を起こしたいわゆるForestier病の1例を経験したので，若干の文献的考察を加え報告する。

We describe a rare occurrence of Forestier disease（diffuse idiopathic skeletal hyperostosis：DISH）presenting with throat discomfort. A 69-year-old man presented with difficulty swallowing of solid foods and chronic cough. Fiberscopic examination disclosed a posterior swelling extending from the middle to the lower pharyngeal wall. The mucosal surface was smooth and flat,and both vocal cords showed good mobility. Lateral cervical radiographs showed ossifications of the anterior longitudinal ligament along the anterior cervical spine from C4-5 to C6-7. CT of the neck confirmed a massive ossification anterior to the cervical spine. Accordingly,the patient was diagnosed of Forestier disease. By his request,no treatment was undertaken,and the ossification was not changed during the observation years.
