Splenic and hepatic ultrasonography were beneficial for diagnosis of lymphosarcoma in 3 horses with anorexia, weight loss, and lethargy. Ultrasonographic abnormalities of the spleen included a large, complex, hypoechoic mass in 1 horse, multiple well-marginated, hypoechoic nodules in 1 horse, and diffuse hyperechogenicity in another horse. Ultrasonographic abnormalities of the liver included a spherical, hypoechoic nodule in 1 horse and diffuse hyperechogenicity in another. Histologic examination of ultrasound-guided biopsy specimens or aspirates revealed lymphosarcoma. Necropsy findings confirmed diagnosis of lymphosarcoma in all horses. Necropsy findings of the liver and spleen correlated well with antemortem ultrasonographic images.
脾脏和肝脏超声检查有助于诊断3匹出现厌食、体重减轻和嗜睡症状的马的淋巴肉瘤。脾脏的超声异常表现为：1匹马出现一个大的、复杂的低回声肿块；1匹马出现多个边界清晰的低回声结节；另一匹马出现弥漫性高回声。肝脏的超声异常表现为：1匹马出现一个球形低回声结节；另一匹马出现弥漫性高回声。超声引导下活检标本或穿刺物的组织学检查显示为淋巴肉瘤。尸检结果证实所有马匹均诊断为淋巴肉瘤。肝脏和脾脏的尸检结果与生前超声图像高度相符。
