CT finding in neoplasms of Hepatobiliary system

Abstract

The orginal and extent of mass lesion could be defined better the ultrasonography. Moving further currently multiphasic contrast enhariced dynamic CT has shown promise in better characterization of the morphology of hepato-biliary tumors with its multiplanar reformats, and phasic study. The prospective study will include 50 patients of hepato-biliary malignancies being treated at Tertiary care Hospital. Before commencing for CT examination all procedure, historical, clinical, laboratory data was recorded. Most common primary was from colorectal malignancy constituting 11 cases (39%), followed by gastric carcinoma (6 cases, 21%), pancreatic malignancy (3 cases, 11%). Majority of the heptic metastasic nodules appear illdefined irregular iso to hypodense (21 out of 28 patients; 785%) on NCCT scan. And no/minimal enhancement noted after contrast study (17 out of 28 patients: 61%). Majority of the metastatic nodules are solitary (64%), and right lobe is most commonly involved (20 out of 28 patients (72%). The mean size of metastatic lesions encountered in our study was 4.2cm.
