A New Ultrasonographic “Fluttering Sign” for Hepatic Hemangioma

The aim of the study described here was to clarify diagnostic value fluttering sign, a new sign that characterizes hepatic hemangiomas in gray-scale ultrasonography (US). It refers phenomenon which speckled echogenicity inside hemangioma changes continuously and seems be moving. A total 172 diagnosed with contrast-enhanced US were evaluated. found 123 (71.5%). Its prevalence significantly higher than marginal strong echo (89/172, 51.7%, p < 0.001), posterior acoustic enhancement (103/172, 59.9%, = 0.031) chameleon (100/172, 58.1%, 0.013). In addition, observed more frequently mixed or hypo-echoic tumors hyper-echoic (p relatively large 0.001) less 5 cm from body surface 0.015). has great potential complementary for diagnosis hemangioma.
