Lymphosarcoma involving cranial nerves in a cat.

Area of Science:

• Veterinary Neurology
• Veterinary Oncology

Background:

• Lymphosarcoma, a common feline neoplasm, can affect various organ systems.
• Cranial nerve involvement by neoplasia is a rare but significant clinical presentation in cats.

Observation:

• A cat presented with clinical signs suggestive of neurological dysfunction.
• Concurrent bilateral otitis media complicated the initial clinical diagnosis.
• Neurological deficits were observed, impacting multiple cranial nerves.

Findings:

• Post-mortem examination confirmed lymphosarcoma as the underlying cause.
• The neoplasm directly infiltrated six cranial nerves.
• Involvement of the anterior cervical ganglion by the tumor was also identified.

Implications:

• This case highlights the importance of considering neoplastic infiltration in feline neurological cases.
• Accurate diagnosis of cranial nerve compromise requires thorough pathological investigation.
• Understanding neoplasm patterns aids in veterinary diagnosis and treatment strategies.
