The aim of this retrospective study was to determine the clinical usefulness of thoracic ultrasonography compared to thoracic radiography in evaluation of Rhodococcus equi pneumonia. Criteria for patient inclusion in this study were: (1) isolation of R. equi from transtracheal aspirate, (2) radiographic evaluation of the pulmonary parenchyma, and (3) sonographic evaluation of the pulmonary parenchyma. Seventeen foals met this criteria and their medical records were reviewed. Pyogranulomatous pneumonia was identified radiographically in 13 foals. Severe consolidative pneumonia with no detectable abscessation was identified radiographically in three others. Both consolidation and abscessation were identified radiographically in one. In this foal only consolidation was ultrasonographically identified. Ultrasonographically, pulmonary abscessation was identified in 12 foals and pulmonary consolidation with no detectable abscessation was identified in three others. Sonographic examination allowed detection of only pleural irregularities in one foal, which was subsequently found to have pyogranulomatous pneumonia radiographically. Results indicate that ultrasonography may be an accurate alternative imaging modality for detection of pulmonary pathology attributed to R. equi pneumonia in foals when thoracic radiography is not available.
这项回顾性研究的目的是确定与胸部X光检查相比，胸部超声检查在评估马红球菌肺炎中的临床实用性。本研究纳入患者的标准为：（1）经气管抽吸物中分离出马红球菌，（2）对肺实质进行X光评估，（3）对肺实质进行超声评估。17匹小马驹符合该标准，并对其病历进行了回顾。X光检查发现13匹小马驹患有脓性肉芽肿性肺炎。另外3匹小马驹X光检查发现严重实变肺炎但未检测到脓肿形成。1匹小马驹X光检查发现既有实变又有脓肿形成。在这匹小马驹中，超声检查仅发现实变。超声检查发现12匹小马驹有肺脓肿形成，另外3匹小马驹有肺实变但未检测到脓肿形成。超声检查仅在1匹小马驹中发现胸膜不规则，随后X光检查发现该小马驹患有脓性肉芽肿性肺炎。结果表明，当无法进行胸部X光检查时，超声检查可能是检测小马驹因马红球菌肺炎所致肺部病变的一种准确的替代成像方式。
