Presumptive central nervous system cuterebriasis and concurrent protein-losing nephropathy in a dog

Abstract

Objective: To describe the clinical course and successful management of a dog suspected to have central nervous system (CNS) Cuterebra larval migration and concurrent protein-losing nephropathy (PLN). Case Summary: A 1-year-old castrated male mixed breed dog was diagnosed with presumptive CNS cuterebriasis based on history, progressively deteriorating mentation, seizures, and magnetic resonance images showing a tubular lesion consistent with a migrating Cuterebra tract. Additionally, serum biochemistry and urine analyses revealed the development of a severe PLN. Surgical removal of the Cuterebra was attempted unsuccessfully, and subsequently, the dog was treated with ivermectin, antihistamines, anticonvulsants, and a tapering dose of glucocorticoids. Over several weeks the dog's neurologic status improved and the PLN resolved completely. New or Unique Information Provided: This case describes successful management of presumptive CNS cuterebriasis in a dog. It is also, to our knowledge, the first report of PLN associated with cuterebriasis in the veterinary literature. © Veterinary Emergency and Critical Care Society 2013.
