Contrast-enhanced sonography (CES) is used with increasing frequency in the assessment of liver focal lesions that have undergone percutaneous ablation therapies. 5 We report a case in which the CES study performed after percutaneous ethanol injection therapy for hepatocellular carcinoma (HCC) showed a perifocal arterioportal fistula. The clues to diagnosis included transient hyperechogenicity of perinodular parenchyma during the arterial phase of enhancement and early opacification of peripheral portal branches adjacent to the treated nodule. Fistula formation was probably due to recent ethanol injections. To our knowledge, there are no previous reports describing the CES features of a peripheral arterioportal fistula.
