Approximately 75% of pulmonary nodules are discovered incidentally on chest radiographs (CXR).2 Th...
متن کاملSmall cell lung cancer presenting as a solitary pulmonary nodule.
BACKGROUND Small cell lung cancer (SCLC) occasionally presents as an asymptomatic solitary pulmonary nodule (SPN) on chest radiography. This group of SCLC patients appears to have different tumor growth properties and greater potential for cure than most SCLC patients. Some investigators have hypothesized that SCLC presenting as a SPN represents a biologically unique subset of SCLC. OBJECTIVE...
متن کاملThe Solitary Pulmonary Nodule.
Due to the high etiological diversity and the potential for malignancy, pulmonary nodules represent a clinical challenge, becoming increasingly frequent as the number of CT examinations rises. The topic gains even more importance as clear evidence for the effectiveness of CT screening was provided by the National Lung Screening Trial (NLST). Yet, the results were tempered by the high false-posi...
