infection is an opportunistic infection that occurs primarily among immunocompromised patients, and the morbidity and mortality of this infection is high if left unrecognized and untreated. There are no clinical or radiographic characteristics typical of cryptococcal pneumonia, and its clinical and radiological presentations often overlap with other diagnoses.
We present a case of a 25-year-old man from Ghana admitted for an altered mental state, weight loss, neck pain, fever, and photophobia. He was diagnosed with meningitis by cerebrospinal fluid culture and with disseminated cryptococcal infection by a positive blood test. Diffuse micronodular opacities were found in a miliary pattern in the upper portions of both lungs upon imaging, which suggested miliary tuberculosis; thus, the patient was started on antituberculosis therapy. The patient underwent flexible fiber optic bronchoscopy, and transbronchial biopsy of the right lung showed bronchopneumonia with fungal spores consistent with filamentous , which grew in tissue culture of the right lung. Interferon-gamma release assay, PCR, and acid-fast bacilli staining of the bronchoalveolar lavage were negative for the complex.
The similarities in clinical and imaging findings among patients with acute immunodeficiency syndrome with coinfections make diagnoses difficult; thus image-guided biopsies are essential to confirm diagnoses.
感染是一种主要发生在免疫功能低下患者中的机会性感染,如果未被识别和治疗,这种感染的发病率和死亡率很高。隐球菌性肺炎没有典型的临床或影像学特征,其临床表现和影像学表现常与其他诊断重叠。
我们报告一例来自加纳的25岁男性病例,因精神状态改变、体重减轻、颈部疼痛、发热和畏光入院。通过脑脊液培养诊断为脑膜炎,血液检测呈阳性诊断为播散性隐球菌感染。影像学检查发现双肺上部呈粟粒样弥漫性微小结节状混浊,提示粟粒性肺结核;因此,患者开始接受抗结核治疗。患者接受了可弯曲纤维支气管镜检查,右肺经支气管活检显示支气管肺炎,伴有与丝状菌一致的真菌孢子,在右肺组织培养中生长。支气管肺泡灌洗的干扰素-γ释放试验、聚合酶链反应和抗酸杆菌染色对结核分枝杆菌复合物均为阴性。
急性免疫缺陷综合征合并感染患者的临床和影像学表现相似,难以诊断;因此,影像引导下活检对于确诊至关重要。
