Nine of 69 dogs with occult heartworm disease (13%) had allergic pneumonitis characterized by consistent clinical and radiographic signs. Although the clinical signs were severe, the degree of radiographic pulmonary arterial abnormalities was mild. Corticosteroid therapy resulted in rapid resolution of clinical and radiographic signs; thiacetarsamide therapy was then given without complications. This syndrome may not be recognized as heartworm-associated and may be confused with other disorders, some being associated with a poor prognosis and requiring different therapy.
69只患有隐匿性心丝虫病的犬中有9只（13%）出现了以一致的临床和影像学表现为特征的过敏性肺炎。尽管临床症状严重，但影像学上肺动脉异常的程度较轻。皮质类固醇治疗使临床和影像学表现迅速缓解；随后给予硫乙酰胺治疗，未出现并发症。这种综合征可能未被认为与心丝虫有关，可能与其他疾病混淆，有些疾病预后不良，需要不同的治疗方法。
