Feline Nervous System Neoplasia Study Guide
Overview and Clinical Importance
Central nervous system (CNS) neoplasia represents an important differential diagnosis in cats presenting with neurological signs. The incidence of primary CNS neoplasia in cats is approximately 3.5 per 100,000 cases, with approximately 2% of all feline neoplasms being intracranial. Primary brain tumors account for approximately 70% of all intracranial neoplasms in cats, making this a critical topic for the NAVLE examination.
Understanding the clinical presentation, diagnostic approach, and treatment options for feline CNS tumors is essential for veterinary practitioners. Cats with CNS neoplasia often present with subtle, slowly progressive clinical signs that can easily be overlooked until the disease is advanced.
Classification of Feline CNS Neoplasms
CNS tumors in cats can be classified based on their origin (primary vs. secondary), anatomic location (intracranial vs. spinal), and relationship to neural tissue (extra-axial vs. intra-axial).
