IMAGING DIAGNOSIS—PULMONARY ALVEOLAR PROTEINOSIS IN A DOG

A young dog was presented for cyanosis and right heart failure. Radiographic and CT characteristics included right heart/pulmonary artery enlargement, hepatomegaly, abdominal effusion, and severe, generalized air‐space filling. Focal increased opacities were present in the peripheral lung, as were multiple pulmonary blebs and bullae. Echocardiographic findings were consistent with cor pulmonale and pulmonary hypertension. Bronchoscopic findings were consistent with chronic inflammation. Pulmonary alveolar proteinosis (PAP) was confirmed at necropsy. Pulmonary alveolar proteinosis is an interstitial lung disease that results in accumulation of phospholipoproteinaceous material and should be included as a differential diagnosis for dogs with these clinical and imaging characteristics.     

肺泡蛋白沉积症的X线诊断与鉴别诊断

目的：探讨肺泡蛋白沉积症（ＰＡＰ）的Ｘ线诊断、Ｘ线分型与鉴别诊断。方法：回顾分析１５例经病理证实的ＰＡＰ的Ｘ线表现,全部病例都作了胸部Ｘ线平片检查,其中３例作了全肺体层。结果：１５例中９例表现为双肺广泛分布的小结节状阴影,３例表现为以肺门为中心,向外放射的蝶冀状阴影,３例表现为双下肺野大片状致密阴影。结论：ＰＡＰ根据Ｘ线表现可分为多发小结节型、类肺水肿型和类炎症型,分别应与肺泡细胞癌、肺水肿及肺部
