Thirteen dogs with splenic masses were subjected to contrast harmonic imaging. Pathologically five of them were diagnosed as having nodular hyperplasma of the spleen (Group 1), another five dogs with splenic hematoma (Group 2), and the remaining three with splenic hemangiosarcoma (Group 3). In Group 1, enhancement of the entire mass was seen in all dogs during the vascular phase, and also seen in four dogs during the parenchymal phase. In Group 2, enhancement of the periphery of the mass was seen in three dogs during the vascular phase, and in only one dog during the parenchymal phase. In Group 3, the periphery of the mass was enhanced in two dogs during the vascular phase, but not in any dog during the parenchymal phase. Consequently, contrast harmonic imaging is considered to be useful in differentiating these diseases, especially in differentiating nodular hyperplasia from splenic hepatoma or splenic hemangiosarcoma.
