Silent pressure: Unveiling spinal lymphoma in horses and its parallels to other species

Summary Though the nervous system is an uncommon location for lymphoma, the disease should remain a differential diagnosis in some cases of ataxia in equids. Diagnosis of lymphoma can be challenging, although a combination of cytology, histopathology and immunophenotyping can aid in definitive diagnosis and therefore more accurately guide treatment and prognostic recommendations. While equine herpesvirus‐5 has been isolated in some cases of equine lymphoma, a clear correlation has not yet been established, in contrast to viral diseases and lymphoma in other species. Further investigation into this area is necessary to better understand the aetiology of equine lymphoma.
