Study of Image Guided Fine Needle Aspiration Cytology (FNAC) in Intra-abdominal and Intra-thoracic masses

Abstract

Objectives: To evaluate diagnostic accuracy, usefulness and limitations of image guided FNAC of intraabdominal and intrathoracic masses. Materials and Methods: This prospective study was done in the Department of Pathology and T.B Chest, RNT Medical College, Udaipur between February 2016 and September 2016. The study included total of 35 cases of which 14 abdominal and 21 thoracic masses. Adequate smears obtained. Smears were stained with Field and May Grunwald Giemsa stain. The cytological diagnosis was correlated with clinical and radiological data to arrive at a final diagnosis. Results: Fine needle aspiration cytology was performed from various anatomic sites: liver (5 cases), ovary (3 cases), pelvis (2 cases), gall bladder (2 cases), omentum and retroperitoneal lymph node each (1 case). Thoracic aspirations were done from the lung (20 cases) and mediastinum (1 case). The most common malignancy encountered in the abdomen was Adenocarcinoma (7 cases). Squamous cell carcinoma was the most common diagnosis amongst the lung lesions (14 cases).Conclusion: Ultrasonography and computed tomography guided fine needle aspiration cytology had a high yield and was helpful in diagnosing deep seated lesions.
