Overview

Case report demonstrates imaging's role in vascular malformations in a cat with paraparesis.

Key Points

  • This report aims to describe a case of spinal arteriovenous fistula and vertebral angiomatosis in a cat, exploring their overlapping manifestations.
  • Imaging techniques used included computed tomography (CT) and magnetic resonance imaging (MRI) to assess the T11 vertebral lesion.
  • Surgical decompression of the lesion was performed, followed by histopathological evaluation for diagnosis.
  • Imaging revealed a vertebral lesion at T11 causing spinal cord compression without typical venous structures or arteriovenous shunts seen in other cases.
  • Histopathological evaluations resulted in diagnoses of both arteriovenous fistula and capillary-type vertebral angiomatosis, indicating potential coexistence.
  • The findings highlight the need for detailed imaging to understand underlying vascular conditions and guide treatment.
