耳性脳膿瘍の2例（治験・剖検例）

　緒言

　最近，化学療法の発展により，慢性中耳炎が潜行性に進行し，患者，医師の全く感知しない間に重要器官の合併症を起こすことが多くなつた。我々は2例の耳性脳膿瘍を経験した。1例は手術後10年余を経過して，健康人として生活している例，1例は外来に元気に通院していた患者が入院2日にして死亡し，剖検により耳性小脳膿瘍と確認し得た例を経験したので，ここに報告し御批判，御指導を仰ぐしだいである。

Two cases of otitic cerebral abcess are re-ported.

Case 1. The diagnosis of cerebral abcess of otitic origin was established in a man, aged 21. The abcess was drained by Ramadier's operative method and during which the abcess cavity was filled with 40% molyodol. The presence of the latter is still evident without any change in its from 10 years after the procedure; the patient is well and has no untoward symptoms.

Case 2. A woman aged 56 died of cerebe-llar abcess of otitic origin. Clinically the pa-tient was affected with external otitis and ch-ronic otitis media; she was afebrile; there was no symptom to suspect cerebral thrombo-sis. The patient suddenly developed difficul-ties in ambulation and balance; three days later she died. The cerebella abcess was found by post-mortem examination.
