AbstractBackground: In this study, we wanted to study the role of triphasic contrast multi detector computed tomography (MDCT) scan in diagnosis of focal hepatic lesions and enhancement patterns of various focal hepatic lesions on triphasic contrast MDCT scan.
Methods: This was a hospital based prospective study conducted among 96 patients who presented with suspected focal hepatic lesions or those suspected or diagnosed with other imaging modalities to the Department of Radiology, Adesh Medical College and Hospital, Mohri, over a period of 6 months from 1st March 2022 to 31st August 2022 after obtaining clearance from Institutional Ethics Committee and written informed consent from the study participants.
Results: Male preponderance (57.2 %) was seen compared to females (42.8 %) with a sex ratio of 1.3 : 1. 57 (59.3 %) were malignant and 39 (40.7 %) were benign. 47.4 % of the hemangiomas were seen in age group of 30 - 39 years, out of the total 19 cases. Male preponderance was seen in hepatocellular carcinoma (HCC) (85.7 %), metastases (55 %), cholangiocarcinoma (66.7 %), simple hepatic cyst (53.8 %) and abscess (60 %). Female preponderance was seen in haemangioma (63.2 %). Out of the total 345 lesions, 213 were hypo vascular lesions accounting for 61.8 % of the cases and 132 were hyper vascular lesions accounting for 38.2 % of the lesions. Out of the 213 hypo vascular lesions, benign lesions included cysts (28.6 %), abscess (5.7 %) and haemangioma (3.8 %). Malignant hypo vascular lesions included metastases (61.9 %). Out of the 132 hyper vascular lesions, benign lesions included haemangioma (47.8 %). Malignant lesions included HCC (50 %) and intrahepatic cholangiocarcinoma (2.2 %). The most common primary site for hepatic metastases was gall bladder (50 %) followed by lung (25 %) and colorectal carcinoma (7.5 %). No visible enhancement was seen in simple hepatic cysts on hepatic arterial phase (HAP, PVP) and delayed phase and the lesions remained hypo dense in all the phases.
