Paragonimosis in a cat and the temporal progression of pulmonary radiographic lesions following treatment.

Abstract

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.
