Role of Ultrasound guided Fine needle Aspiration in diagnosis
of liver mass lesion

Fine Needle Aspiration of the liver is a simpler
technique and is reported to yield higher positivity in patients
with hepatic malignancy as compared to core biopsy. Fine
needle aspiration cytology has the advantage of causing
significant less discomfort and a very low risk of complication.
Of all the radiological procedures the ultrasound is most suited
for fine needle aspiration cytology as real time images can be
obtained and it prevents the perforation of gall bladder, colon
and blood vessels, Ultrasound has higher level of practicality,
requires no ionizing radiation and is widely applicable as
compare to computerised tomography scan. Aim of the present
study is to establish role of Ultrasound guided Fine Needle
Aspiration in diagnosis of liver mass lesions.
Methods : We have performed UGS guided FNAC on 42
suspected cases of liver mass lesion. Detail history, clinical
examination was done and consent was taken from patient
after explaining the procedure to them. Bleeding time, Clotting
time and Prothrombin time were done prior to procedure. All
patients with liver mass lesion diagnosed on radiology were
included in the study. Under all aseptic precaution Ultrasound
guided FNAC was done from liver mass lesion using 26 gauge
lumbar puncture needle. The material obtained in the needle
was expelled onto glass slide and smear was made by
opposition technique.
Results: Of 42 aspirates from liver, 13 were diagnosed as
hepatocellular carcinoma, 23 were diagnosed as metastatic
carcinomas. Attempt of grading and study of cellular patterns
was done in hepatocellular carcinoma. Of 23 cases of metastatic
carcinoma, in 11 cases primary site could be demonstrated. In
12 cases primary site could not be determined. 18 were
adenocarcinomas and 5 were undifferentiated anaplastic
carcinoma.
Conclusion: Ultrasound guided Fine Needle Aspiration of liver
mass is safe ,cost effective technique in localizing Liver lesion
and acquiring adequate material for preoperative diagnosis of
mass lesion of liver
