ABSTRACT: INTRODUCTION: Liver disease is one of the most significant cause of morbidity and mortality and includes a broad spectrum of disorders such as infections, metabolic and neoplastic disorders that finally results in hepatic dysfunction. Ultrasound has been an accepted method for diagnosis of focal & diffuse hepatic lesions because of its rapidity of diagnosis & high sensitivity. This study has been conducted to diagnose different types of focal and diffuse hepatic lesions by ultrasonography as a prime imaging modality and to assess the validity of ultrasonographic diagnosis in relation to FNAC diagnosis. AIMS AND OBJECTIVES: To study the pattern of liver disease, in local patient population admitted to various clinical departments of BTGH which would alter further management of patients. To study validity of USG diagnosis in relation to FNAC diagnosis & operative findings. MATERIALS AND METHODS: All patients presenting with varied clinical features suggestive of liver Diseases: 1. Abnormal liver function tests. 2. Congenital disease involving liver. 3. All patients of malignancy. RESULTS: Out of 118 cases, 73 cases were males and 45 were females. Males had increased predilection for liver diseases. Primary malignant liver tumors, metastasis, liver abscess have highest incidence in the age group of 41-50 years with 13, 11 and 8 cases respectively. Metastatic deposits in the liver not found below 20 years of age. Heamangioma, Cyst, Hydatid cyst were noted up to the age of 60 years. Fatty liver, cirrhosis has highest incidence in the age group of 31-40 years with 5, 3 cases respectively. Diffuse hepatocellular carcinoma have highest incidence in the age group of 51-60 years with 2 cases. CONCLUSION: Ultrasound is a rapid, Non-ionizing, Non-invasive, safe, relatively reliable, economical investigation and does not require special preparation prior to the examination. By this rapid method, even small lesions with subtle difference in reflectivity can be detected. Ultrasonography is also very helpful in diagnosing or ruling out any other associated disease or any pathology gallbladder, kidneys, pancreas, spleen, lymph node and any other organ simulating liver disease.
