Abstract
Objectives: Objectives of the study were to study the Enhancement Pattern of various hepatic masses using Triphasic CT as diagnostic modality, differentiating different hepatic masses and to compare our findings with that reported in literature
Methods:A total of 60 patients were seen in this cross-sectional study done inDepartment of Radiology,Tikur Anbessa specialized Hospital (TASH) Addis Ababa,Ethiopia from October, 2017 to September, 2018. All patients underwent Triphasic CT examination and diagnosis were made by histopathology/typical imaging findings, follow up, and clinical and lab findings as applicable.
Results: Our study included 60 patients with hepatic focal mass masses; most common neoplasm was metastases (38.3%) followed by hepatocellular carcinoma(HCC)which accounted for 31.6 % and hemangioma which accounted for15% of cases. Peripheral intrahepatic cholangiocarcinoma accounted for 5 % cases.The enhancement patterns of HCC were as follows: 57.8% demonstrate heterogeneous hypervascularenhancement inthe arterial phase and totallyhypovascular in the delayed phase, while 36.8% showed homogeneous hypervascular pattern. Almostall of the HCC (100 %) appeared as totall hypovascularmasses in thedelayed phase. In the case of hemangiomas, 73.3 % showsGlobular peripheral enhancement in the arterial phase; in the delayed phase, 60 % showed complete centripetal filling in which is iso vascularto vessels. In the arterial phase,60.8 % ofmetastases were hypovascular. In the delayed phase, all (100%) werehypovascular.Metastases were most commonly hypovascular in all phases (60.8%).
Conclusions: Triphasic CT with its high accuracy is helpful in confia hepatic masses. It has an indispensable role in evaluating and characterizinghepaticmasses which helps in guiding appropriate management plan with proper surgicaltriage.
