We report meconium aspiration in 2 sibling goat kids, and characterize the expected lesions of aspiration pneumonia in conjunction with the rare lesion of otitis media. Grossly, the lungs were multifocally consolidated, and there was yellow-green exudate within the middle ear. Histologically, the lung was characterized by pyogranulomatous pneumonia and foreign-body reaction around aspirated debris. Within the lumen of the middle ear, aspirated squamous cells, keratin, meconium debris, and neutrophils, without evidence of bacteria, were accompanied by a subepithelial accumulation of lymphocytes, plasma cells, and fewer macrophages. This is an especially rare phenomenon, which is thought to result from transport of meconium from the oropharynx through the auditory tube (Eustachian tube) to the middle ear.
我们报告了2只同胞山羊幼崽的胎粪吸入情况，并结合罕见的中耳炎病变描述了吸入性肺炎的预期病变。大体上，肺呈多灶性实变，中耳内有黄绿色渗出物。组织学上，肺的特征为脓性肉芽肿性肺炎及吸入碎片周围的异物反应。在中耳腔内，吸入的鳞状细胞、角蛋白、胎粪碎片和中性粒细胞（无细菌证据）伴有淋巴细胞、浆细胞和较少巨噬细胞的上皮下积聚。这是一种特别罕见的现象，被认为是胎粪从口咽通过咽鼓管运输至中耳所致。
