VMED 5248 – CNS Tumors | Veterinary Medical Neuroscience
– Lecture Summary with Classification and Pathology
1. What are two common neurologic signs associated with brain tumors?
Ataxia and fever
Palpable mass and epistaxis
Seizures and CN deficits
Nasal discharge and congestion
2. Describe the key distinction between intraaxial and extraaxial brain
tumors.
Intraaxial tumors are always benign, while extraaxial tumors are
malignant.
Intraaxial tumors are more common than extraaxial tumors in
adults.
Intraaxial tumors originate from within the brain's parenchyma,
while extraaxial tumors arise from outside the brain's
parenchyma.
Intraaxial tumors compress the spinal cord, while extraaxial tumors
do not.
3. What is a common diagnostic method for lymphoma in the central
nervous system?
CSF tap or FNA
X-ray
,Blood test
CT scan
, 4. What condition is often caused by a pituitary tumor in a horse that
compresses the hypothalamus?
seizures
ataxia
hypertrichosis/hirsutism
hypoglycemia
5. Describe how behavioral changes can indicate the presence of a
cerebral tumor.
Behavioral changes are unrelated to brain tumors.
Behavioral changes may occur due to increased intracranial
pressure or direct effects on brain function.
Behavioral changes are only seen in peripheral nerve sheath
tumors.
Behavioral changes indicate a systemic infection.
6. Describe the typical neurological signs that may indicate the presence of
a focal lesion in dogs with intracranial tumors.
Increased appetite is a common sign.
Seizures are always present in all cases.
Generalized weakness indicates a systemic issue.
Lateralized neurologic signs suggest a focal lesion.
7. What is the most common primary intracranial tumor in dogs and cats?
Meningioma
Pituitary tumor
Neuroblastoma
