Paragonimosis in a Cat and the Temporal Progression of Pulmonary Radiographic Lesions Following Treatment

A 16 mo old cat presented with a 5 mo history of dyspnea, coughing, and gagging. Radiographic findings revealed seven nodules measuring 1–3 cm distributed multifocally in the lungs. Examination of feces revealed large numbers of eggs of Paragonimus kellicotti. Two fenbendazole treatment regimens (28 mg/kg per os q 12 hr for 21 days) and prednisone were required to eliminate the infection. Resolution of pulmonary nodules was monitored for 8 mo following successful treatment, and four lesions were still partially visible at 8 mo.
