Using helical CT and rapid IV 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.
