Sonographic findings correlated with necropsy findings in 8 of 9 horses in which the cranial portion of the mediastinum was evaluated by use of both methods. Cranial mediastinal masses were imaged as multilobular and homogeneously hypoechoic; a complex echogenic pattern was observed with necrosis within the mass. Pleural effusion was a common finding in horses with mediastinal lymphosarcoma. Cytologic evaluation of pleural fluid samples was useful in diagnosis of lymphosarcoma in 10 of 12 horses that had thoracentesis. Sonographic examination of the thorax and cranial portion of the mediastinum can aid in the diagnosis of mediastinal lymphosarcoma in horses. Such examination should be performed in horses with clinical signs of cranial vena cava obstruction in which pleural effusion is detected, or when thoracic lymphosarcoma is suspected.
在9匹使用两种方法评估纵隔前部的马匹中，有8匹马的超声检查结果与尸检结果相关。纵隔前部肿块在超声下表现为多叶及均匀低回声；肿块内坏死区域呈现复杂的回声模式。胸腔积液是马匹纵隔淋巴肉瘤的常见表现。对12匹接受胸腔穿刺的马匹中的10匹而言，胸水样本的细胞学评估有助于诊断淋巴肉瘤。对胸部及纵隔前部进行超声检查有助于诊断马匹的纵隔淋巴肉瘤。对于出现颅腔静脉阻塞临床症状且检测到胸腔积液的马匹，或怀疑患有胸部淋巴肉瘤的马匹，均应进行此项检查。
