The ultrasonographic appearance of the spleen and adjacent organs in 12 dogs with splenic lymphosarcoma was reviewed. Poorly marginated hypoechoic to anechoic nodules (4 mm to 3 cm in diameter) were found in all dogs. The anechoic nodules did not result in reflective shadowing or acoustic enhancement of the underlying tissues. The remainder of the splenic parenchyma appeared relatively hypoechoic when compared with the liver or renal cortices in 9 dogs. Recognition of this ultrasonographic pattern appears to be a useful diagnostic tool. Needle aspiration guided ultrasonographically will then enable histologic confirmation of lymphosarcoma.
回顾了12只患有脾淋巴肉瘤的犬脾脏及相邻器官的超声表现。所有犬均发现边界不清的低回声至无回声结节（直径4毫米至3厘米）。无回声结节未导致其下方组织的反射性阴影或声增强。与9只犬的肝脏或肾皮质相比，脾脏实质的其余部分显得相对低回声。认识到这种超声模式似乎是一种有用的诊断工具。然后，在超声引导下进行针吸活检将能够对淋巴肉瘤进行组织学确诊。
