To present the high-resolution computed tomography (HRCT) findings of pulmonary alveolar microlithiasis.
The HRCT scans of 10 adult patients (seven females and three males; mean age, 38.7 years) were retrospectively analyzed. The films were studied independently by two radiologists.
The most common tomographic findings were ground-glass attenuation and linear subpleural calcifications, which were seen in 90% of the patients. Other relevant findings were small parenchymal nodules, calcification along the interlobular septa, nodular cissures, subpleural nodules, subpleural cysts, dense consolidations, and a mosaic pattern of attenuation.
The HRCT findings presented by individuals with pulmonary alveolar microlithiasis are distinct. In most cases, such findings can form the basis of the diagnosis, eliminating the need to perform a lung biopsy.
介绍肺泡微石症的高分辨率计算机断层扫描（HRCT）表现。
回顾性分析10例成年患者（7例女性，3例男性；平均年龄38.7岁）的HRCT扫描结果。两位放射科医生独立研究这些影像。
最常见的断层扫描表现为磨玻璃样衰减和胸膜下线性钙化，90%的患者可见。其他相关表现包括小的实质结节、小叶间隔钙化、结节状叶间裂、胸膜下结节、胸膜下囊肿、致密实变以及衰减的马赛克样表现。
肺泡微石症患者的HRCT表现具有特征性。在大多数情况下，这些表现可作为诊断依据，无需进行肺活检。
