Hemangiosarcomas (HSAs) are rare neoplasms in cats, with cutaneous and subcutaneous forms occurring more frequently than visceral HSAs and often associated with chronic ultraviolet radiation exposure. Herein, we report a case of vestibular syndrome secondary to subcutaneous hemangiosarcoma in a 2-year-old cat....
No actionable change for human audiology practice — this is a veterinary case report in a cat with no direct translation to human audiological or vestibular clinical management.
While not directly applicable to human audiology, this case highlights the potential for systemic malignancies to manifest with vestibular signs, a diagnostic consideration relevant across species in vestibular medicine broadly.
- 01Single case report of a cat presenting with vestibular syndrome concurrent with subcutaneous hemangiosarcoma.
- 02Published ahead of print in Topics in Companion Animal Medicine (2026); PMID 42437610.
- 03Suggests a possible paraneoplastic or direct link between the tumor and vestibular dysfunction in this patient.
- 04Evidence is limited to one animal subject; no causal relationship can be established.
- 05No human subjects involved; findings are not directly transferable to clinical audiology practice.
Vestibular syndrome in the cat was associated with subcutaneous hemangiosarcoma.
