Aims and objectives
Growth is one of the most important characteristics of lung cancer[1-3].
Research data show that when low-dose computed tomography(CT) scan is used for baseline screening of lung cancer,
the detection rate of pulmonary nodules is 5%-51% in the general population with 20% on average per round[4].
Most (> 90%) nodules are benign[4-6].
Many suspected nodules are stable during 1-2 years of follow-up visits,
and thus excluded from the positive ones[5,7].
If the nodules during follow-up visits are enlarged gradually,
they will be highly suspected of lung cancer.
However,
not all the growing nodules found during follow-up visits are lung cancers,
and there are still a small number of benign nodules[8,9],
some of which had the same doubling time as lung cancers.
By correctly judging these growing benign pulmonary nodules rarely seen,
unnecessary intervention can be avoided.
In this article,
the imaging features of growing benign pulmonary nodules in 5 cases were analyzed as follows.
