Plain-English summary

A 14-year-old Morgan gelding was brought in because he was getting weaker and losing muscle. Initially, the vet thought he had equine protozoal myelitis, a disease caused by a parasite that affects the nervous system, based on his symptoms and test results. Unfortunately, even with treatment, the horse continued to get worse and had to be put to sleep. A post-mortem examination showed that he actually had a rare type of cancer called neurotropic lymphoma.

Abstract

A 14-year-old Morgan gelding was presented for progressive weakness and muscle atrophy. The horse was initially diagnosed with equine protozoal myelitis based on history, physical examination, and laboratory diagnostics. Despite therapy, the horse declined clinically and was euthanized. Necropsy revealed a rare form of neurotropic lymphoma, described in this report.
