Abstract

Background: The purpose of the present study is to evaluate the accuracy of TNAB for the
diagnosis of benign and malignant lung lesions.
Methods: The present study included 50 patients from June 2020 to June 2021. Our
retrograde study on CT- guided or ultrasound guided lung biopsy on tertiary care center of
Bihar Indira Gandhi Institute of Medical Science.
Results: Out of malignant lesions, most were adenocarcinoma 71.87% followed by
squamous cell carcinoma 15.63%, poorly differentiated carcinoma 9.38% and non-hodgkins
lymphoma 3.12%. In the benign lesions, most of the cases were non-specific inflammatory
lesion 44.45% followed by granulomatous lesion 27.78%, A-V malformation 11.12%,
neurofibroma 5.55%, spindle cell lesion 5.55% and necrosis 5.55%.
Conclusion: The ability to diagnose only malignant lesions by TNAB would markedly limit
the efficacy of that technique, since surgery would be performed on most malignant lesions
diagnosed by TNAB as well as on the lesions not diagnosed by TNAB.
