Role of Ultrasound Imaging in Hepatic Lesions and its Correlation with Fine Needle Aspiration Cytology

Abstract

Introduction: Ultrasound is cheaper, effective, quick, painless,
non-invasive with no radiation hazard. Guided FNAC of the
liver is a safe, simple, cost-effective and accurate method
for cytological diagnosis of hepatic lesions. To study the role
of sonography findings including color doppler in Hepatic
Lesions and its correlation with Fine Needle Aspiration
Cytology.
Materials and Methods: Patients referred to the department
of Radiodiagnosis for sonological evaluation were screened
for hepatic SOLs. Patients with liver SOL were included in the
study . Protocols included History, Routine laboratory and
conventional radiological investigations, Ultrasonographic and
Colour Doppler examination for size, margins, and color flow,
intrahepatic bile duct status and lymph nodes followed byUSG
guided FNA of the lesions & cytological co-relation
Results: Out of 54 patients (28 male and 26 females), 37
patients had malignant (metastatic/primary) lesions and 12
had benign lesions. In 5 patients samples were inadequate for
analysis. Maximum no of malignant cases were 15, in the age
group of 41-60 years and benign cases were 5 each, in age less
than 40 years and in age group 41 to 60 years.On ultrasound,
28 patients had single lesions while 26 had multiple lesions.
Most of the patients (30/54) had lesions in right lobe while only
10 patients had lesions in left lobe. In 14 patients, lesions were
present in both lobes.
Conclusion: The sensitivity and specificity of ultrasound
findings with Fine needle aspiration cytology was 78.4% and
91.7% respectively for diagnosis of malignant lesions.
