Context:
Computerized tomography (CT) guided fine needle aspiration cytology (FNAC) of lung lesions has rapidly emerged as a less-invasive, cheap, rapid and fairly accurate diagnostic aid in lung lesions.
Aims:
The purpose of this present study was to evaluate the effectiveness of CT-guided FNAC in the diagnosis of pulmonary mass lesions (both benign and malignant) and to determine the complication rate of this procedure.
Settings And Design:
We conducted an institution-based, prospective study on 127 patients who presented with pulmonary mass lesions.
Materials And Methods:
After proper consent was obtained, CT-guided transthoracic fine needle aspiration was done and their diagnoses were confirmed by appropriate methods. The results were analyzed statistically.
Results:
Out of 127 cases selected for the study, 59.8% were males while the rest were females. Cough was the most common symptom present in 71.2% cases, followed by weight loss (62.4%). 21.2% cases were cytologically benign. Adenocarcinoma (54.2%) was the commonest malignant tumor. FNAC provided at least 96% sensitivity and 100% specificity in diagnosing lung tumors. Among the benign lesions, specific diagnoses were obtained in 48.1% cases. Thus, altogether a specific diagnosis was obtained in 109 of 127 cases, i.e. 85.8%. No major complication was noted.
Conclusions:
CT-guided FNAC is an extremely valuable and fairly accurate diagnostic aid of intrathoracic mass lesions, with a reasonable rate of complication.
