Spinal Cord Meningioma in a Cat: Long-Term Outcome and Recurrence

An approximately three-year-old male neutered mixed breed cat, 3.8 kg, was presented for a four-month history of tetraparesis, which progressed to tetraplegia in the last week. The animal tested positive for the Feline Immunodeficiency Virus. Neurological examination revealed the absence of proprioception in the four limbs and hyperreflexia, with the maintenance of superficial and deep pain. Magnetic resonance imaging (MRI) showed intra or extradural extramedullary neoformation of probable neoplastic etiology in the C2 vertebral body extending to the C1–C2 intervertebral foramen, more evident in the left dorsolateral region. Left hemilaminectomy in C2, incision of the dura mater, and removal of a smooth and multilobulated mass (1.4 x 0.9 x 0.8 cm) were performed. Histopathological examination of the lesion identified low-grade meningioma. The cat remained clinically normal for three years after surgery. After this period, clinical signs recurred, and MRI confirmed tumor recurrence. The animal underwent a second left hemilaminectomy and tumor removal. The recurrence of the disease after three years highlights the potential for regrowth even in low-grade meningiomas and underscores the importance of long-term monitoring.
