title: Computed tomography guided percutaneous transthoracic fine needle aspiration cytology in chest masses.
abstract: A retrospective, hospital based descriptive study was done to know the pathological spectrum of thoracic lesions and to correlate the radiological findings with cytological findings obtained from computed tomography guided percutaneous transthoracic fine needle aspiration of chest mass. The clinical, radiological and cytological data of 100 patients were studied who underwent CT guided FNAC from May, 2004 to May, 2007. Diagnostic accuracy of FNAC is 82%. Cytological examination showed that 51 cases were malignant and 31 cases were benign. Provisional diagnosis based on radiological findings were 50 and 32 cases of malignant and benign lesions respectively. Sensitivity and specificity, positive and negative predictive value of radiological findings in this study was 88%, 84%, 90% and 81% respectively. Post procedure complication were (a) pneumothorax in two cases and both the cases had to be hospitalized for active management (b) minimal perilesional hemorrhage and hemoptysis in three cases and (c) chest pain in six cases. CT guided FNAC is a simple and safe procedure with high diagnostic accuracy in the evaluation of focal chest lesions. Pneumothorax, perilesional hemorrhage, hemoptysis and chest pain are the usually encountered complications. Very few cases of complication require active management.
