Ultrasonography of sclerosing angiomatoid nodular transformation in the spleen.

We report three rare cases of sclerosing angiomatoid nodular transformation (SANT) in the spleen. We compared the conventional and contrast-enhanced ultrasonographic appearance. The conventional sonographic examinations exhibited solitary lesions without common respects, while contrast-enhanced ultrasonography (CEUS) revealed nodular appearance mimicking its pathologic characteristics. It suggests that CEUS can provide morphologic information for diagnosing SANT.
