Retrospective study of 91 lung cancer patients with mediastinal lymph nodes. CT images acquired between 2012-2015 with 38 patients receiving contrast. Texture analysis performed using free software Mazda
Cavitary lung lesions are frequent findings on imaging, mainly caused by malignancies and infections. CT scan provides more accurate diagnosis than conventional radiography. Cavities contain gas surrounded by variable thickness walls
Lipomas are common in anterior mediastinum, representing 1.6-2.3% of primary mediastinal tumours. Thymolipomas are rare, well-encapsulated thymic tumours with 50-95% fat content. Mediastinal cysts represent 15-20% of primary mediastinal masses. Bronchogenic cysts are rare, typically located near carina
SCC accounts for 30-35% of all lung cancers. Most commonly caused by heavy smoking. Male smokers tend to have higher incidence. Exposure to toxic agents like nickel may increase risk
Pulmonary involvement occurs in over 90% of sarcoidosis patients. Most common in patients aged 20-40, with female predominance. Approximately 50% of patients are asymptomatic. Respiratory symptoms and skin changes are common presentations
Atelectasis refers to lung collapse that can be minor or profound. Resorptive atelectasis occurs due to airway obstruction, causing air absorption. Passive atelectasis results from disrupted pleural contact and natural recoil. Compressive atelectasis arises from thoracic space-occupying lesions. Cicatrisation atelectasis occurs from scarring or fibrosis
