We retrospectively assessed the computed tomography features of intrapulmonary lymph nodes confirmed by cytology in 18 patients. The median size of the lymph nodes was 5.8 mm (range=3.3-8.5 mm). All were below the carina, and only one nodule, which was associated with an interlobar fissure, was over 20 mm from the chest wall. The nodules were oval, round, triangular, or trapezoidal; had sharply defined borders; were solid and homogenous; and were without calcification. Six nodules (33.3%) had a discrete thin tag extending to the pleura. Intrapulmonary lymph nodes can reliably be confirmed by fine needle aspiration with cytological diagnosis.
我们回顾性评估了 18 例经细胞学证实的肺内淋巴结的 CT 特征。淋巴结的中位数大小为 5.8mm（范围=3.3-8.5mm）。所有淋巴结均低于隆突，只有一个结节与叶间裂有关，距离胸壁超过 20mm。结节呈椭圆形、圆形、三角形或梯形；边界清晰；为实性且均匀；无钙化。6 个结节（33.3%）有一个延伸至胸膜的离散的细标签。细针抽吸细胞学诊断可可靠地证实肺内淋巴结。
