奴卡氏菌广泛分布于自然界,多引起人类足菌肿病及肺部感染。据手头资料国内已有两例奴卡氏菌足菌肿,两例巴西奴卡氏菌病引起皮下多处脓肿及一例星形奴卡氏菌脑脓肿的报道。由于该菌感染易误诊为一般细菌化脓感染或结核,加之奴卡氏菌又对大多数抗菌素不敏感,故甚易延误治疗。现报告一例耳源性奴卡氏菌脑脓肿误诊为结核的临床现理资料,以引起临床医师的重视。 Numerals are widely distributed in nature, causing many human pus swollen and lung infections. According to the information on hand, there are two cases of domestic nocardiococcal footbugs, two cases of subarachnoid bursa caused by Brazil’s Nocardiosis and one case of Nocardia asymptomatic brain abscess.

Now report a case of otorhinolaryngocarcinoma brain abscess misdiagnosed as tuberculosis clinically relevant information to attract clinicians attention.
