tailieunhanh - Diagnosis of solitary pulmonary nodules: An updated review

Small lung nodule is a common problem in pulmonary practice. The definition of a classical solitary pulmonary nodule is a single, spherical, well-circumscribed, radiographic opacity less than or equal to 30 mm in diameter that is completely surrounded by aerated lung and is not associated with atelectasis, hilar enlargement, or pleural effusion. Ideally, the goal of diagnosis and management is to promptly bring to surgery all patients with operable malignant nodules while avoiding unnecessary thoracotomy in patients with benign disease. In fact, causes of solitary pulmonary nodules can be benign or malignant. In order to diagnose causes of solitary pulmonary nodules, we can use many different methods, including clinical symptoms, radiographic features, liquid biopsy, bronchoscopy, CT-guided fine-needle aspiration biopsy and surgery. Each method has its own value. It is very meaningful if we can diagnose these causes early. Based on these results, doctors can determine the strategy to manage disease. | journal of military pharmaco-medicine no7-2019 DIAGNOSIS OF SOLITARY PULMONARY NODULES AN UPDATED REVIEW Dao Ngoc Bang1 Ta Ba Thang1 Do Quyet2 SUMMARY Small lung nodule is a common problem in pulmonary practice.

Keywords Solitary pulmonary nodule Diagnosis. 1. Causes and proportion of solitary pulmonary nodules The definition of a classical solitary pulmonary nodule SPNs is a single spherical well-circumscribed radiographic opacity less than or equal to 30 mm in diameter that is completely surrounded by aerated lung and is not associated with atelectasis hilar enlargement or pleural effusion 1 . Causes of SPNs are very variety with 2 main groups benign or malignant ones table 1 . The estimated prevalence of each etiology varies among different populations. Even among screening studies of smokers who are at increased risk of malignancy the number of malignant nodules is small. Among 12 029 nodules found in a large Canadian study only 144 1 were malignant 2 . 1. 103 Military Hospital 2. Vietnam Military Medical University Corresponding author .
