Résumé : Posterior enhancement beyond liver hemangiomas was retrospectively assessed on 89 hemangiomas of all size and localization within the liver. This enhancement is seen only beyond big and complex lesions, containing hypoechoic or anechoic zones. Conversely, it seems to be very rare beyond little hyperechoic lesions. It is necessary to disthinguish true enhancement and a mirror artefact beyond lesions of all sizes but localized just near the diaphragma. In the lesions of less than 2 cm, no clear posterior enhancement was discovered, but some of them showed a very clear mirror artifact.
