Imaging of benign hepatic masses.
Using helical CT and rapid i.v. injection of contrast material, benign hepatic masses are discovered in at least 20% of subjects. To minimize expensive and invasive evaluation, an orderly approach to the interpretation of these lesions is necessary. Many benign lesions have a near pathognomonic appearance on a properly performed and interpreted CT scan. Others can have the diagnosis confirmed by a specific and well-chosen follow-up study, such as contrast-enhanced MR. In this article we present the most common types of benign hepatic masses and our approach to their diagnosis.
