Salivary mucocele associated with dirofilariasis in a dog.

Abstract

Salivary mucocele associated with dirofilariasis was diagnosed in a dog with a mass in the cranioventral cervical region. The diagnosis was based on the finding of microfilariae in fluid aspirated from the mucocele, immunoassay confirmation of circulating Dirofilaria immitis antigen, and the finding of an adult filariid within the mucocele. Drainage of the mucocele and treatment of the D immitis infection resulted in resolution of the mucocele and dirofilariasis.
