PURPOSE: To report contrast-enhanced sonography (CEUS) for solitary necrotic nodule (SNN) of the liver and to assess its clinical value. METHODS: CEUS was performed in 17 patients with pathologically proven SNN. Contrast pulse sequencing and the contrast agent SonoVue were used to depict lesion vascularity at a low mechanical index. The enhancement patterns were evaluated in real time. RESULTS: Lesions were depicted as perfusion defects throughout all phases on CEUS. CONCLUSIONS: CEUS can be a convenient imaging modality for the differential diagnosis of SNN and may obviate the need for further imaging studies.
