颅内舌下神经鞘瘤极罕见,文献上也只不过是一些零星报道.de Martel于1933年做了首次报导,到1969年只报导10例,目前总共报导了21例.本文报告一例结合文献复习,就文献中的18例及作者1例共19例进行了归纳分析.本病以长期半侧舌麻痹和萎缩为其特征.据日本全国病例统计,颅内神经鞘瘤占颅内肿瘤的7.3%,以听神经瘤为最多见,其次为三叉神经鞘瘤,迷走神经鞘瘤,舌下神经鞘瘤占第四位.田村报告316例颅内神经鞘瘤中,听神经瘤占95.8%,三叉神经鞘瘤占2.4%,迷走神经鞘瘤占1.2%,舌下神经鞘瘤占0.6%.本病多发生于中年人.女多于男.
Intracranial hypoglossomas are rare and the literature is only sporadic. De Martel made his first report in 1933 and reported only 10 cases in 1969. A total of 21 cases have been reported so far. Review, 18 cases in the literature and 1 case in 19 cases were analyzed. The disease is characterized by long-term half-paralysis and atrophy. According to the national case statistics of Japan, intracranial schwannoma accounts for intracranial tumors. In 7.3%, acoustic neuroma was the most common, followed by trigeminal schwannoma, vagal schwannomas, and sublingual schwannoma in fourth place. Tamura reported that in 316 cases of intracranial schwannoma, acoustic neuroma accounted for 95.8% of the trigeminal nerve Schwannoma accounted for 2.4%, vagus schwannomas accounted for 1.2%, sublingual schwannomas accounted for 0.6%. The disease occurred in middle-aged people. More women than men.
