Intramedullary lumbosacral teratoma in a domestic ferret (Mustela putorius furo)

Abstract

An 18-month-old, female, spayed domestic ferret ( Mustela putorius furo) was presented for progressive hind limb paresis of 1 week duration. The ferret was mentally appropriate but cachexic and ataxic with neurological deficits, which localized the lesion to the lumbosacral region. A depression in the lumbosacral spine was associated with discomfort on palpation. Results of whole body radiographs were consistent with an abnormal angle between vertebrae L6 and S1, which resulted in hyperflexion of the spine. The ferret was euthanized, and histopathological examination revealed an intramedullary lumbosacral teratoma effacing much of the spine in the region of the mass.
