title: Eosinophilic pulmonary granulomatosis in a young dog with prolonged remission after treatment.
abstract: A two-year-old Jack Russell terrier was presented for evaluation of chronic cough and exercise intolerance. Previous treatment with antibiotics and glucocorticoids had only partially ameliorated the clinical signs. During investigation, hypoxaemia, peripheral eosinophilia and an eosinophilic bronchoalveolar lavage fluid were noted. Thoracic radiographs revealed two ovoid clearly delineated soft-tissue opacities, one in the caudal segment of the left cranial lung lobe (diameter 26 mm) and the other in the right cranial lung lobe (diameter 20 mm). These findings were verified by computed tomography, which identified an additional smaller lesion (diameter 16 mm) dorsally in the right caudal lobe. Ultrasound-guided fine-needle aspiration samples confirmed the diagnosis of eosinophilic pulmonary granulomatosis and treatment with prednisolone and azathioprine was initiated. Within 1 month, granulomas were no longer detectable radiographically. All medication was discontinued after 7 months and currently, after 2·5 years, the dog remains free of clinical signs. To the authors' knowledge this is the first case report to describe prolonged remission from idiopathic canine eosinophilic pulmonary granulomatosis.
