Abstract

A 6-year-old, male entire French Bulldog was presented for a 2-month history of progressive ambulatory tetraparesis and occasional cervical pain. Neurological examination was consistent with a right-sided C1–C5 myelopathy. Magnetic resonance imaging revealed an intradural-extramedullary mass over the C1–C2 vertebrae. The mass was surgically excised, and histopathological examination demonstrated a neoplastic vascular proliferation within a fibrous-myxoid stroma. Immunohistochemical staining allowed further characterisation of the lesion, which was consistent with a solitary fibrous tumour (hemangiopericytoma). The patient improved neurologically after surgery. This type of tumour had not been previously reported in dogs in this location.
