Abstract
Background- For the detection and characterization of focal hepatic mass lesions, ultrasonography and multi-detector computed tomography (CT) play a primary role. With the widespread of cross-sectional imaging, a growth of incidentally detected focal liver lesions (FLL) has been observed. A reliable detection and characterization of Focal liver lesions is critical for optimal patient management. Maximizing accuracy of imaging in the context of focal liver lesion is paramount in avoiding unnecessary biopsies, which may result in post-procedural complications.
So the vast spectrum of the focal liver lesions and their corresponding contrast enhancement characteristics were observed and tabulated to look for specificity of contrast patterns and tabulate a organised approach towards the diagnosis.
Materials-Sixty non-consecutive patients belonging to all ages and both sexes admitted into the various clinical departments of Krishna institute of medical sciences, Karad were examined with a triphasic liver CT protocol and histopathology/FNAC.Equipments Used USG :Siemens (Accuson x 300). 3.5 MHz frequency transducer and Siemens Emotion system 16 slice MDCT
Results Conclusions- Out of 60 the spectrum of lesions seen were Hepatocellular carcinoma (20%) (Out of which 9 cases were in cirrhotic livers and 3 in non-cirrhotic livers), Metastasis (33.3%), Hydatid cyst (2%), Abscess (5%), Haemangioma (13.3%), GB carcinoma, Cholangiocarcinoma and other (5% each) and simple liver cysts (10%).
