摘要: Purpose Anthracosis often results in mediastinal nodal enlargement. The aim of this comparative study was to evaluate if it is possible differentiate endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) proven anthracotic lymph nodes from malignant node enlargement by means multislice computed tomography (MSCT). Methods We compared the MSCT findings 89 enlarged due anthracosis with 54 (non-small cell lung cancer 75.9%, small 18.5%, and non-Hodgkin lymphoma 5.6%). were assessed for density (calcification, fat, necrosis), shape (oval, round), contrast enhancement, contour (sharp, ill-defined). Results Malignant showed significantly greater axis diameters (P Conclusion Our show that there are significant differences benign anthracosis.
