The ultrasonographic appearance of hepatic hemangiomas was studied in 19 patients (31 lesions). The detectability rate by real-time ultrasonography was 77%. A hyperechoic, sharply-marginated and internally homogeneous lesion is highly suggestive of hemangioma. If the hypoechoic lesion has homogeneous internal echoes and/or strong marginal echoes, it is also suggestive of hemangioma. It is difficult to detect small lesions in the lower lateral part of the right lobe and lesions in the right lobe immediately under the diaphragm. Computed tomography should be the next procedure of choice in the evaluation process. If the computed tomography is not characteristic, angiography should be done to confirm the diagnosis.
对19例患者（共31个病灶）的肝血管瘤超声表现进行了研究。实时超声检查的检出率为77%。高回声、边界清晰且内部均匀的病灶高度提示为血管瘤。如果低回声病灶内部回声均匀和/或边缘回声强，也提示为血管瘤。右叶外侧下部的小病灶以及紧邻膈肌下方右叶的病灶难以检测到。在评估过程中，计算机断层扫描应作为下一步的首选检查。如果计算机断层扫描表现不典型，则应进行血管造影以确诊。
