摘要

禽型分枝桿菌群(MAC)是一種環境中常可發現的菌種。它可生長淤正常人體的表皮及器官而不致病。此菌種造成感染一般是發生在後天免疫不全的病人身上，尤其當CD4細胞數掉到50/ul以下時，此時病人的抵抗力極弱，容易形成機會感染。而免疫力正常的人偶有感染，大多發生於肺部有宿疾的病人，而感染部位多在肺部。肺外局部性MAC感染在免疫力正常的人極為少見。我們報告一個73歲男性，因為MAC感染引起心包積水，其HIV檢驗結果為陰性。經外科手術引流心包積水並送檢培養的結果證實為MAC感染。

We present a case of Mycobacterium avium complex (MAC)-induced cardiac tamponade in an immunocompetent man. MAC is ubiquitous and can inhabit the human body without causing disease. Infections with this organism are generally associated with an immunocompromised status, particularly advanced AIDS, as a late opportunistic infection. Sometimes the organism may cause non-tuberculous pulmonary disease in immunocompetent people with preexisting lung disease. Focal extrapulmonary MAC infection in immunocompetent patients is extremely rare, with very few reports in the literature. However, this case serves to remind us that atypical mycobacterial infection must also be considered in immunocompetent patients.
