 The most commonly encountered malignancy across the globe are lung tumours, making it the leading cause of cancer related mortality with an average of 4.5 years survival rate. (1)There is an increase in utilisation of CT thorax as an imaging tool to evaluate symptomatic patients leading to incidental findings of suspicious lesions. Earlier bronchofiberscopywas donebut, the diagnostic accuracy of bronchofiberscopywas 60% (2)that’s when role of CT came into picture. CT guided fine needle aspiration cytology (FNAC) and Biopsy are simple methods to diagnose lung cancer especially in peripherally situated or sonographically unattainable lesions. CT guided FNAC implied by Martin and Ellis first as a tool for diagnosis.(3) Later Nordenstrom continued the work was carried forward by Nordenstrom who gave promising results that showed that this procedure can achieve accuracy in diagnosis with less complication.(4) The diagnostic accuracy of FNAC and biopsy is 93% and sensitivity rate is 95% .(5) There are various however manageable complications noted with this procedure like pneumothorax (8–69% of cases (6)),haemoptysis and pulmonary haemorrhage.
