Introduction: Lung cancer is the most common cancer among men with presenting diverse presentations. It can present as an incidental isolated nodule or mass to obstructive pneumonia, pleural effusions or lymphangitis carcinomatosis. Diagnosis is done by cytology or histologically obtained by bronchoscopy, pleural fluid analysis or CT-guided sampling of mass or nodules. CT has the advantage of accuracy at the cost of radiation, cost and need for technical skills. Ultrasound has recently emerged as important imaging of choice for not only pleural effusions but also for parenchymal lesions. Ultrasound has the advantage of portability, and non-radiation but needs skills in the identification and sampling of lesions. This study aimed to assess the diagnostic yield of ultrasound-guided FNAC /Biopsy of radiologically suspected peripheral lung lesions. An institution based prospective study was conductedMaterials and methods: over a span of 2 years on 62 patients with informed consent. FNAC was performed under USG guidance for peripheral lung nodules/masses, with clinical & radiological suspicion of neoplasm in chest radiographs. All relevant medical records including history, USG, CT scan, histopathological diagnosis and bronchoscopic findings are collected and analysed. Out of 62 cases selected for the study (n=48, 77.41%) male preponderance was seen. The commonestResults: age group was (n=26, 41.93%) between 60 – 75 years. The commonest symptom (n=50, 80.64%) being cough and common site for lesion (n=20, 32.25%) was upper zone lesions, with an equal incidence of both right and left sides. Of the 62 patients 58 have histologically positive diagnosis of malignancy. Squamous cell carcinoma (n= 26, 41.93%) was the commonest. One patient suffered from pneumothorax with no mortality related to the procedure. USGConclusions: guided FNAC is an extremely valuable, safe imaging modality in the evaluation of peripheral nodules/masses with excellent diagnostic yield.
