頭蓋内悪性リンパ腫

Intracranial Malignant Lymphoma

I．はじめに

　頭蓋内悪性リンパ腫は極めて稀な疾患であると考えられてきたが^2,12,27），次第に増加傾向にある，それはCT導入以来，この疾患の発見率が高まったためでもある．1965年4月1日以来，京大脳神経外科で経験した頭蓋内悪性リンパ腫19例につき，若干の文献的考察を加え，特にその臨床的特徴に関して検討する．

We experienced 19 histologically verified intracranial malignant lymphomas during the period of 15 years from April 1, 1965 to August 31, 1979. From the analysis of cases of our own and from the literature, the followings are considered to be the clinical characteristics of intracranial malignant lymphomas.

1) Males were more affected than females.

2) The highest frequency was observed in the 5th to 7th decades.

3) Increased intracranial pressure, motor disturbance, and psychic or consciousness disturbance were 3 cardinal symptoms.

4) Tumors were localized frequently in the paraventricular region.
