めまいと突発性一側聾を初期症状とした悪性リンパ腫剖検例—連続切片による検討

Autopsy Case of Malignant Lymphoma with Initial Symptoms of Vertigo and Unilateral Sudden Deafness: A Study with Serial Sections.

　I．はじめに

　悪性リンパ腫は原発性にも続発性にも中枢神経系に発生しうる腫瘍のひとつであり，その頻度は一般に低いと考えられているが^1〜4），かならずしも稀でないとの報告もある^5〜7）。私共はめまいと突発性一側聾を初期症状として発症した同腫瘍剖検例を経験したので，その臨床神経症候学と解剖学的所見の相関，ならびに文献的考察を加えて報告する。

　A clinico-anatomical study on infratentorial malignant lymphoma in a 58-year-old woman who showed positional vertigo when she turned her head toward her right, and subsequently unilateral sudden deafness in the right ear as the inital symptoms of the illness is reported. She developed various right-sided clinical manifestations such as hemifacial numbness, loss of taste, hemifacial palsy, hemipharyngeal palsy, hoarseness due to recurrent nerve paralysis and cerebellar signs of the right extremities. She also showed interesting nystagmus. The tumor occupied the right cerebelloponto-medullary junction. Clinico-anatomical correlations were discussed.
