眼窩内meningoceleによる搏動性眼球突出症の1治験例

A CASE OF PULSATING EXOPHTHALMOS DUE TO INTRA-ORBITAL MENINGOCELE

はじめに

　頭蓋内容の眼窩内浸入により生じた搏動性眼球突出は比較的稀なものであるが，本疾患の報告例は主として眼科領域からとり挙げられており，脳神経外科領域で取扱われた治験例は非常に少ない。最近われわれは，intra—orbltal meningoccleと，眼窩後壁骨欠損にもとづく搏動性眼球突出を呈した一症例に頭蓋内形成術をおこない完治せしめ得たのでここに報告し，若干の文献的考察を加えてみる。

The pulsating exophthalmos due to intra-orbital encephalocele or meningocele associating with orbital bone defect is rare phenomenon.

Recently, we have experienced a case of 40 years old female showing uniteral exophthalmos. On the symptom, it was characteristic that this exophtha-lmos subsides and rather sinks after removal of cerebrospinal fluid by lumbar puncture and P. E. G. procedure. An acurate diagnosis was established by means of various X-ray examinations.

On the operation we found the meningocele located on the right temporal tip and accorded with the retro-orbital bone defect, extending to the orbital roof, lateral side of small wing and cerebral side of large wing of sphenoidal bone. The re-moval of the meningocele and plastic procedure with tetron mesh for the bone defect brought to comlete disappearance of the exophthalmos.

We reported a case and concidered in reference to this problem on the literature.
