Abstract
Background: CT-scan is a very useful diagnostic tool for the detection of hepatic mass. Objective: The present study was undertaken to determine the CT-scan findings of benign and malignant hepatic mass patients. Methodology: This was a cross sectional study conducted in Radiology and Imaging Department at Mymensingh Medical College Hospital (MMCH), Mymensingh; Dhaka Medical College Hospital (DMCH), Dhaka and Banghabandhu Sheikh Mujib Medical University (BSMMU), Dhaka with the collaboration of Pathology Department of the same institute for histopathological confirmation. This study was carried out from January 2006 to December 2007 for a period of 2 years. The patients who were clinically suspected of having hepatic mass attended in the Radiology and Imaging Department in the above mentioned institutes were included as study population. All the CT-scan findings were recorded. Result: A total number of 50 patients were enrolled for this study. CT-scan was done among 40 males and 10 females with a mean age of 51.28 years old. Hypodensity was found in 17 (60.7%) and 18 (81.8%) cases in malignant and benign hepatic lesions respectively. Ill-defined margin was detected in 12 (42.9%) and 6 (27.3%) cases respectively. Calcification was present on 11 (39.3%) malignant lesion and 6 (27.3%) benign lesions. Pressure effect on biliary apparatus was found in 11 (39.3%) malignant lesions and 1 (4.5%) benign lesions (p < 0.05). Lymphadenopathy was found in 10 (35.7%) malignant lesions and 1 (4.5%) benign lesions (p < 0.05). Conclusion: In conclusion, CT-scan findings of malignant and benign hepatic mass show hypodensity with more contrast enhancement in malignant lesions with more calcification in malignant lesion; however, significant difference is detected in pressure effect on biliary apparatus and lymphadenopathy.
Highlights
Hepatic mass is commonly detected liver mass [1]
In CT-scan hepatic lesion like hepatocellular adenoma shows a clear margin with encapsulated mass [4]
On unenhanced CT-scan, hepatocellular carcinoma (HCC) appears hypodense to liver; post-contrast CT images are required for the detection and characterization of HCC [5]
Summary
Hepatic mass is commonly detected liver mass [1]. It is very urgent need to determine its nature whether it is solid or cystic, benign or malignant, single or multiple [2]. There are several imaging techniques which are used to detect hepatic mass like ultrasonography, computed tomography of scan and so on. On unenhanced CT-scan, hepatocellular carcinoma (HCC) appears hypodense to liver; post-contrast CT images are required for the detection and characterization of HCC [5]. Objective: The present study was undertaken to determine the CT-scan findings of benign and malignant hepatic mass patients. The patients who were clinically suspected of having hepatic mass attended in the Radiology and Imaging Department in the above mentioned institutes were included as study population. Hypodensity was found in (60.7%) and (81.8%) cases in malignant and benign hepatic lesions respectively. Conclusion: In conclusion, CT-scan findings of malignant and benign hepatic mass show hypodensity with more contrast enhancement in malignant lesions with more calcification
