The formation of cranial thoracic masses (CTM) as a sequel to infectious pleuropneumonia is described. Using ultrasound, masses were diagnosed subjectively as abscesses or loculations. Eight of 99 cases with pleuropneumonia had CTM. Clinical signs associated with the presence of a CTM included increased heart rate, jugular distention, forelimb 'pointing' and caudal displacement of the heart. Techniques used for diagnostic ultrasonographic examination of the cranial thorax are described. Five of the eight horses with CTM responded to conservative medical management; the other three required percutaneous drainage of the mass to relieve worsening signs of cardiac decompensation. Improvements in cardiovascular parameters were evident within 12 h of drainage. The indications for and limitations of invasive drainage of cranial thoracic masses are discussed.
描述了作为传染性胸膜肺炎后遗症的颅胸部肿块（CTM）的形成。使用超声，肿块被主观诊断为脓肿或局部积液。99例胸膜肺炎病例中有8例出现CTM。与CTM存在相关的临床体征包括心率加快、颈静脉扩张、前肢“指向”和心脏尾侧移位。描述了用于颅胸部诊断性超声检查的技术。8例患有CTM的马匹中有5例对保守药物治疗有反应；另外3例需要对肿块进行经皮引流以缓解心脏代偿失调的恶化体征。引流后12小时内心血管参数有明显改善。讨论了颅胸部肿块侵入性引流的适应症和局限性。
