Role of Needle Aspiration Biopsy in the Diagnosis of Mass in Chest

Abstract

Patients presenting at Mayo Hospital Chest Surgery Ward (Teaching Unit) who bad mass lesion in the lung on X-Ray were included in this study. Needle aspiration biopsy was done in all patients except for 05 cases. A total of 105 cases were studied between January 1997 to June 1999. Out of these, 80 were male, and 25 were female. There ages ranged between 10- 90 years. Fine needle aspiration was also carried out in 101 out of 105 cases yielding an overall diagnostic value of 67.33%. It revealed tissue ¡n 62 cases (61.39%), fluid in 28 cases (27.72%). Positive yield of needle aspiration biopsy in centrally located lesion was up to 23.53% whereas in peripherally located lesion mounted to 76.19%. This study revealed that needle aspiration biopsy of peripheral lung lesions or larger lesions is a very safe, quick and reliable method for establishing the diagnosis of mass chest. Moreover it showed better results in peripherally located lesions.
