Cerebral aspergillosis is a rare cause of brain expansive lesion in AIDS patients. We report the first culture-proven case of brain abscess due to Aspergillus fumigatus in a Brazilian AIDS patient. The patient, a 26 year-old male with human immunodeficiency virus (HIV) infection and history of pulmonary tuberculosis and cerebral toxoplasmosis, had fever, cough, dyspnea, and two episodes of seizures. The brain computerized tomography (CT) showed a bi-parietal and parasagittal hypodense lesion with peripheral enhancement, and significant mass effect. There was started anti-Toxoplasma treatment. Three weeks later, the patient presented mental confusion, and a new brain CT evidenced increase in the lesion. He underwent brain biopsy, draining 10 mL of purulent material. The direct mycological examination revealed septated and hyaline hyphae. There was started amphotericin B deoxycholate. The culture of the material demonstrated presence of the Aspergillus fumigatus. The following two months, the patient was submitted to three surgeries, with insertion of drainage catheter and administration of amphotericin B intralesional. Three months after hospital admission, his neurological condition suffered discrete changes. However, he died due to intrahospital pneumonia. Brain abscess caused by Aspergillus fumigatus must be considered in the differential diagnosis of the brain expansive lesions in AIDS patients in Brazil.
脑曲霉病是艾滋病患者脑部占位性病变的罕见病因。我们报告了巴西首例经培养证实的由烟曲霉引起的脑脓肿艾滋病患者。该患者为一名26岁男性,感染人类免疫缺陷病毒(HIV),有肺结核和脑弓形虫病史,出现发热、咳嗽、呼吸困难及两次癫痫发作。脑部计算机断层扫描(CT)显示双侧顶叶和矢状旁低密度病变,周边强化,并有明显的占位效应。于是开始进行抗弓形虫治疗。三周后,患者出现精神错乱,新的脑部CT显示病变增大。他接受了脑活检,引出10毫升脓性物质。直接真菌学检查发现有分隔的透明菌丝。开始使用去氧胆酸盐两性霉素B治疗。对该物质的培养显示存在烟曲霉。在接下来的两个月里,患者接受了三次手术,插入引流导管并在病灶内注射两性霉素B。入院三个月后,他的神经状况出现轻微变化。然而,他因院内肺炎死亡。在巴西,艾滋病患者脑部占位性病变的鉴别诊断中必须考虑烟曲霉引起的脑脓肿。
