Asymptomatic solitary pulmonary nodules incidentally revealed by computed
tomography has become a serious medical problem. Depending on their diameter,
solid, part-solid, or pure ground-glass pulmonary nodules may be observed,
diagnosed radiologically/invasively, or resected in accordance with international
guidelines. Pure ground-glass nodules, semi-solid lesions, or solid lesions
smaller than 8 mm should be monitored by serial low-dose computed tomography. In
the case of solid nodules greater than 8 mm, the assessment of the risk of
malignancy is recommended. Patients at high risk of lung cancer with pulmonary
lesions should undergo diagnostic investigation, or the nodule should be
resected. If the risk of lung cancer is low, the patients may be monitored.
Needle aspiration biopsy is the most important invasive method of tumor
diagnosis. Cytological or histopathological diagnosis is helpful in appropriate
clinical decision making that reduces the risk of unnecessary surgery, decreasing
the rate of benign nodule resections and thus reducing the costs of medical
treatment.
