No full textContrast-enhanced ultrasound was used to study focal and multifocal lesions of the spleen in 26 dogs and two
cats affected by 11 benign and 18 malignant splenic diseases. A second-generation microbubble contrast medium
(Sonovue) was injected into the cephalic vein and enhancement patterns were subjectively described and time
intensity curves calculated. Final diagnosis was obtained by histopathologic examination after splenectomy
(n1⁄419) or by needle aspiration and sonographic follow-up after 4 and 8 weeks (n1⁄49). Contrast-enhanced
ultrasound parameters, improving the characterization between benign and malignant lesions, were established.
The most useful criterion was the hypoechogenicity of the lesion in the wash-out phase combined with the
presence of tortuous feeding vessels, which was observed in association with malignancy. All malignant lesions
were hypoechoic to the surrounding spleen 30 s after starting the contrast medium injection. Lymphosarcoma
and hemangiosarcoma had characteristic perfusion patterns. Lymphosarcoma had rapid time to peak and early
wash-out phase with a honeycomb pattern during the wash-out. Hemangiosarcomas were large nonperfused
masses in all phases surrounded by hypervascular splenic parenchyma. Benign lesions except one hematoma and
a benign histiocytoma had the same perfusion pattern as the surrounding spleen. Ultrasonographic and contrastenhanced
ultrasound findings of an accessory spleen are reported. Contrast-enhanced ultrasound can improve
the characterization of focal or multifocal lesions of the spleen
