Plain-English summary
An 8-year-old mare mule was brought to the vet because she had a growth on her face and had stopped eating. She was also having a nosebleed on one side and had thick, pus-like discharge from her nose. Tests showed that she had several masses in her chest, and a detailed scan revealed that these masses were spreading into nearby tissues. Given the severity of her condition and the likelihood that the cancer had spread, her owner decided to have her euthanized. A post-mortem examination confirmed that she had hemangiosarcoma, a type of cancer that affects blood vessels, which had spread to multiple organs.
Abstract
An 8-year-old mare mule was presented with a facial mass and history of anorexia, unilateral epistaxis and purulent nasal discharge. The facial mass was encountered from the ventral to the lateral right canthus of the eye up to the facial crest. Thoracic ultrasonography showed five rounded masses. A standing CT under sedation was performed revealing a huge extension and infiltration on surrounding tissues. Due to the extension, type of lesions, outcome and suspicion of metastasis, the owner chose to euthanize the patient. Necropsy confirmed the presence of tumoral lesions spread into the lungs, spleen, adrenal glands, ovary, oral cavity, and right frontal sinus. The microscopic examination was consistent with hemangiosarcoma. Hence, hemangiosarcoma is a differential diagnosis to rule out  in future similar cases. This clinical description did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.
