Indigenous Australians have a high prevalence of chronic lung diseases. However, no previous studies have reported on cystic lung disease in an Indigenous patient cohort.
This report describes 20 adult Indigenous patients noted to have incidental lung cysts on chest computed tomography (CT) while being referred to undergo lung function tests in the Northern Territory of Australia.
Of the total 20 Indigenous patients demonstrating presence of pulmonary cysts on chest CT scan, 13/20 (65%) were males with a mean age of 49.9 years (range 24-74 years), with no significant difference in age between males and females. The majority reported a smoking history and spirometry demonstrated moderate reduction in lung function parameters. While there was no pattern in the size or location of cysts, most demonstrated multiple cysts (55% had ≥5 cysts) with bilateral involvement (65%), alongside a range of concurrent pulmonary radiological abnormalities. The aetiology for lung cysts was largely unknown.
This is the first report to illustrate cystic lung disease within an Indigenous population. Further radiology studies are required to investigate the causes and prognostications of cystic lung disease in Indigenous patients.
澳大利亚原住民慢性肺部疾病的患病率很高。然而，此前尚无研究报道过原住民患者队列中的囊性肺病情况。
本报告描述了20名成年原住民患者，他们在澳大利亚北领地被转诊接受肺功能测试时，胸部计算机断层扫描（CT）发现有偶然的肺囊肿。
在胸部CT扫描显示存在肺囊肿的20名原住民患者中，13/20（65%）为男性，平均年龄49.9岁（范围24 - 74岁），男女年龄无显著差异。大多数患者有吸烟史，肺功能测定显示肺功能参数有中度降低。囊肿的大小和位置没有规律，大多数表现为多发囊肿（55%有≥5个囊肿），双侧受累（65%），同时伴有一系列肺部放射学异常。肺囊肿的病因大多不明。
这是第一份阐述原住民人群中囊性肺病情况的报告。需要进一步的放射学研究来调查原住民患者囊性肺病的病因和预后。
