Abstract
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.
