Frequent Atypical Pattern: Hemangioma with Echoic Border

An atypical but suggestive appearance of hemangiomas at US is the following: The lesion has an echoic border, which is seen as a thick echoic rind or a thin echoic rim. Unlike typical hemangiomas, this type of hemangioma has an internal echo pattern that is at least partially hypoechoic. The central low echogenicity is assumed to correspond to previous hemorrhagic necrosis, scarring, or myxomatous changes. The corresponding CT and MR imaging appearances of hemangiomas with echoic borders are not precisely described in the literature; in most such cases, we have observed typical patterns at CT or MR imaging. Although the real percentage is unknown, some authors have reported that 40% of all hemangiomas could have this atypia.
