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.
Highlights
Morphological evaluation of lung lesions like size, location, contour, edge, density, calcification and enhancement pattern in contrast study can only narrow down the diagnostic possibilities
Computed tomography guided fine needle aspiration cytology is considered a procedure of choice in the evaluation of focal chest lesions.[2]
After institutional approval the clinical, radiological and cytological information of 100 patients were obtained from the hospital data who underwent CT guided fine needle aspiration cytology (FNAC) from May, 2004 to May, 2007
Summary
Morphological evaluation of lung lesions like size, location, contour, edge, density, calcification and enhancement pattern in contrast study can only narrow down the diagnostic possibilities. Cytological diagnosis is warranted before initiating the specific treatment for malignant disease.[1]. Computed tomography guided fine needle aspiration cytology is considered a procedure of choice in the evaluation of focal chest lesions.[2] It is a simple and safe procedure with high diagnostic accuracy for the diagnosis and cell typing of lung cancer where Ultrasound (USG) guided procedure is not possible.
