中脳水道閉塞症に合併した非外傷性髄液鼻漏

NON-TRAUMATIC CEREBROSPINAL FLUID RHINORRHEA ASSOCIATED WITH AQUEDUCTAL OBSTRUCTION

　非外傷性髄液鼻漏は1826年にMillerが最初の詳細な報告を行なつて以来100余例が報告されている。Om—mayaはそれにつき綿密な検討を行ない，頭部外傷・開頭術・耳鼻科手術などの後に発生するもの（いわゆる外傷性髄液鼻漏），及び頭蓋内腫瘍・頭蓋内先天性異常などによる髄膜や骨の欠損から発生するもの（いわゆる非外傷性髄液鼻漏）に大別した。

　これらのうち外傷性髄液鼻漏はしばしば経験されるものであり，特に頭部外傷によるものは多く，これは外科的治療を行なわずとも大部分のものは保存的療法で治癒する。

The authers reported a case of 38-year-old woman who consulted our clinic with the complaints of the episodes of headache, vomiting, and unconscious-ness three times in about two months.

She stated that she had been troubled with rhinorrhea since the winter of 1969, when she had a cold, and that diagnosis of allergic rhinitis had been made. She also claimed suffering from an-osmia since her childhood.

X-ray examination revealed aqueductal obstruc-tion, and no vascular lesion was found. By MVG myodil was shown to come into her left nasal cavity, and she was found to have non-traumatic cerebrospinal fluid rhinorrhea.

Though the causes of aqueductal obstruction and non-traumatic cerebrospinal fluid rhinorrhea were not clear in this case, characteristic symptomes and signs of the non-traumatic cerebrospinal fluid rhinorrhea were discussed here in detail by re-viewing the literatures.
