次级肺小叶是肺结构的基本单位，它再现了肺的缩影。气道、肺动脉、静脉、淋巴管和肺间质均位于次级小叶水平。次级小叶的几个组成部分通常在肺部的薄层计算机断层扫描 (CT) 扫描中可见。识别与次级小叶结构相关的肺部异常对于解释薄层 CT 扫描至关重要。薄层 CT 扫描可见的继发小叶解剖结构的病理改变包括小叶间隔增厚以及小叶周围分布、小叶中心异常和全小叶异常的疾病。小叶异常的鉴别诊断基于小叶解剖结构和肺部病理学之间的比较。
The secondary pulmonary lobule is a fundamental unit of lung structure, and it reproduces the lung in miniature. Airways, pulmonary arteries, veins, lymphatics, and the lung interstitium are all represented at the level of the secondary lobule. Several of these components of the secondary lobule are normally visible on thin-section computed tomographic (CT) scans of the lung. The recognition of lung abnormalities relative to the structures of the secondary lobule is fundamental to the interpretation of thin-section CT scans. Pathologic alterations in secondary lobular anatomy visible on thin-section CT scans include interlobular septal thickening and diseases with peripheral lobular distribution, centrilobular abnormalities, and panlobular abnormalities. The differential diagnosis of lobular abnormalities is based on comparisons between lobular anatomy and lung pathology.
