title: Computed tomogram guided fine-needle aspiration cytology of lung and mediastinal masses with cytological correlation: a study of 257 cases in Western region of Nepal.
abstract: Computed tomogram guided fine needle aspiration cytology (FNAC) is an important and useful investigation to differentiate between benign and malignant lesions of lungs. To evaluate the lung and mediastinal masses and to analyze and compare the results with cytological findings, 257 patients were retrospectively studied who underwent CT guided FNAC over a period of 2007 to 2013. The study was done in patients who presented with respiratory symptoms with a localized lung lesion which was confirmed radiologically. 252 cases of lung masses and 5 cases of mediastinal cases were included. Patients' age ranged from 24 to 84 year and the male to female ration was 1.2:1. Radiologically, out of 257 cases, 225 cases were given as malignant, 8 cases as benign and 24 cases as inflammatory lesions. Cytologically, 212 cases were malignant, 12 cases were benign and 21 cases were inflammatory. Most common lung malignancy was adenocarcinoma (87 cases) followed by squamous cell carcinoma (56 cases). 8 cases of lung metastasis were seen. Compared to biopsy, CT guided FNAC shortens the diagnostic interval and helps in differentiating lung malignancy into different cytopathological types which aids in proper management of the malignant lesion.
