Abstract
Background: This study was aimed to evaluate the role of transthoracic ultrasound guided
FNAC in diagnosis of peripheral lung lesion. It is an important and useful investigation to
differentiate between benign and malignant lesions of lung. USG guided FNAC of lung lesion
is a safe, radiation free, and cost effective method. Besides, the procedure is simple and
complications if occur, can be managed conservatively.
Methods: This was a cross-sectional study conducted at the department of Pathology,
Rajshahi Medical College. Some samples were also collected from a private diagnostic centre,
Rajshahi over a period of one year from January 2021 to December 2021. 150 patients who
fulfilled inclusion criteria were included in this study. After properly explaining the procedure
and taking informed consent, USG guided FNAC was done in all the patients. Radiological
and cytological data of enrolled patients was collected prospectively and analyzed.
Results: Among the 150 patients, this study comprising of 120 male and 30 female in age
range of 21 to 90 years. Malignancy was the most common cytological diagnosis (76%) while
as benign diagnosis was reached in 22.66%. In 1.33% of patients, FNAC was inconclusive.
Squamous cell carcinoma was the most common malignancy diagnosed in 46(30.66%)
patients, followed by adonocarcinoma 31(20.66%), 19(12.66%) patients had undifferentiated
carcinoma, metastatic carcinoma 09(06%), small cell carcinoma 07(4.66%), and Non Hodgkin
lymphoma was diagnosed in 02(1.33%) patients. Among the benign group, nonspecific
chronic inflammation was diagnosed in 18(18%) patients, tuberculous granuloma 07(4.66%),
while the smear was inconclusive in 02(1.33%) patients.
Conclusion: Ultrasound guided fine needle aspiration cytology is safe, less expensive, less
time consuming, less invasive diagnostic tool with high degree of accuracy and no radiation
toxicity to lung lesions
