腰背部に左側方腫瘤を形成したMeningomyeloceleの1症例

A Case of Paravertebral Lumbar Meningomyelocele

Ⅰ．緒言

　小児中枢神経系の先天奇形の中で，spina bifida cysticaは，しばしば経験される疾患であるが^4），cystの大部分は正中線上に位置するものであり，前方または側方に生じる例は稀である．特に，腰椎のレベルで外側に生じたspina bifida cysticaの報告は，我々の知る限りでは，本邦においてはなく，文献上4例^2，3，5）を数えるにすぎない．

　このたび我々は，左，腰背部にcystを形成し，その上，多くの他の奇形を合併したsplna bifida cysticaの1症例を経験したので報告する．

A case reported here is one year-old girl, who was admitted to our neurosurgical service because of gradually increasing swelling in the left lumbar region, and maldevelopment and paresis of the left leg since birth. From the level of L-2 to S-1, there was a 8×7cm subcutaneous swelling of lipomatous consistency with well-defined margins.

Of particular characteristics was that the swelling didn't cross the midline and was entirely located in the left paravertebral region (Fig. 1). In the spine no gap could be felt between the spinous processes.
