[Focal liver lesions as incidental findings. 2: Diagnostic procedures in sonographically homogeneous echo-rich, echo-poor or inhomogeneous lesions].
Hemangioma is one of the most common incidental findings in the ultrasonographic image. In 80% to 90% of the cases, the hemangioma presents as a homogeneous lesion in the US image. In asymptomatic patients and a lesion diameter of less than 2 cm, further clarification additional to ultrasonography is not necessary. Major differential diagnoses are focal nodular hyperplasia, metastasis, hepatocellular carcinoma and liver cell adenoma. With exceptions, the biological significance of echo-poor or inhomogeneous lesions cannot be established on the basis of the US image. In such cases, additional diagnostic procedures are required.
