Nocardia常可在免疫功能不全的病人身上造成機緣性感染，而其中由Nocardia所造成的腦部膿瘍常常造成極高的致死率。我們在此提出一個因感染Nocardia otitidiscaviarum造成腦部膿瘍的個案，在經過顱骨切開術併膿瘍清除的手術之後，施予Trimethoprim-sulfamethoxazole，Meropenem及Amikacin的抗生素治療，因而成功治癒的例子。

Nocardia can cause serious opportunistic infections in immunocompromised patients. Nocardial brain abscess in these patients has a high mortality. We describe a patient with Nocardia otitidiscaviarum brain abscess. After the abscess was evacuated at craniotomy, the patient was treated successfully with trimethoprim-sulfamethoxazole, meropenem, and amikacin.
