髄膜瘤の3例—特に脳圧亢進に関する考察

THREE CASES OF MENINGOCELE:Relation of the Hydrocephlus

I．はじめに

　われわれは，最近それぞれ後頭部，頸部および腰部に発生した髄膜瘤の3例を経験した。この髄膜瘤は幾多の奇形を合併することが多く，なかでも水頭症が多い。また，膀胱直腸障害や下肢の麻痺などの神経障害をしばしば伴う。この疾患は発生頻度も比較的少なく，生下時髄膜瘤を発見した場合，水頭症の有無，嚢腫切除と脳圧亢進との関係および脳室心房連絡術の適応などについて，正しい診断をくだすことは容易ではない。われわれは自験例を報告するとともに，これらの問題に関し若干の文献的考察を加えてみた。

We reported three cases of meningocele.

Case 1. His sac was in the occipital region, which was repaired within the day of his birth. The sac had a narrow neck and contained no neural content. At 3 years old, he was in good condition and showed no signs of hydrocephalus.

Case 2. Her sac was in the cervical region, which was repaired at 20 days after her brith. The sac had a quite narrow neck and contained no neural content.

At 3 months old, she was in good condition and showed no signs of hydrocephalus.

Case 1 and case 2 were not associated with other congenital anomlies.

Case 3. Her sac was in the lumbal region, which was not repaired.

Ventriculo-atriostomy was persumed at 3 months old when head growth significantly exceeded the expected rate. She was associated with clubfoot. At 3 years old, she could walk with difficulty and suf-fered from rectovesical disturbance, but showed en-tirely normal mental development.

A few problems of clinical aspect of the cranium bifidum and spina bifida, especially in the relation to hydrocephalus was discussed with review of the literatures.
