Plain-English summary

A 25-year-old saddlebred stallion was diagnosed with hemangiosarcoma, a type of cancer that affects blood vessels, which was causing pressure on his spinal cord. He showed signs of trouble with coordination and weakness in all four legs, which got worse over time. When the horse passed away, a mass was found in his spinal canal that contained abnormal cells and a lot of blood. Tests confirmed that this mass was indeed a tumor. Unfortunately, the treatment options for this condition were not mentioned, but the diagnosis indicates a serious health issue.

Abstract

Hemangiosarcoma in the spinal canal was diagnosed in a 25-year-old stallion showing progressive and symmetrical 4-limb ataxia, proprioceptive deficits, and weakness. On necropsy, an extradural mass consisting of spindle-shaped cells and numerous free erythrocytes was found at the level of C7-T1. Immunohistochemical staining confirmed a neoplasm of endothelial origin.
