腦室に破れたる耳性腦膿瘍2治験例

　緒言

　腦膿瘍の経過中，側腦室と交通するに到れば予後は絶対的不良なりとされ，現今に到るも未だ十指に余る治験例の報告を見るのみなり．昭和17年斯る疾患の治験例を得て報告せり．更に最近化学療法の目覚しき発達により，耳性頭蓋内合併症の予後は著しく改善せられ最早それ等疾患治験例の報告は価値無きが如き観を呈せるも，独り腦室と交通せる腦膿瘍に於ては然らす，之が治験例に接する事尠し．幸い当教室に於て最近再び同樣の症例を得たので，前例と共にここに報告する．

KITAMURA AND NAKAGAWA report 2 cases of cerebral abcess that originated from cholesteatoma-tous otitis media. Patients were men aged 39 and 25 respectively. In both cases the symptoms that the abcess had ruptured into the lateral ventricle were markedly prominent; the first on the sixth day after the original cerebral abcess had been drained externally and the second showing such symptoms to be well established at the time of patient's admittance to the hospital. In either case drainage of the ventricle externally made a good progress' through the abcess cavity and the patients made uneventful recovery.

Continuity between the abeess cavity and the ventricle in these cases was confirmed by roentge-nograms taken after injections of radio-opapue moljodol.
