1

Most common complaints of patient's with brain tumors

- progressing focal neuro deficit
- seizures
- Non focal neuro disorders (HA, personality change, gait disturbances, other increased ICP sx's)

2

Brain tumor treatment

SYMPTOMATIC; most cannot be excised

glucocorticoids, anti-seizure meds, radiation/chemo

3

Most common primary intracranial neoplasm

Astrocytomas

4

Low vs high grade astrocytomas

Low = children, cerebellum (Grade I excellent prognosis, but Grade II 5-6 yrs)

High = adults; supratentorial location; life expectancy < 1 yr

5

Generally have more benign course with longer life expectancy than astrocytomas. Some may be totally excised (cured)

Oligodendroglioma

6

Most frequent brain tumor in children; HIGHLY MALIGNANT

medullablastomas and PNET

7

Glioma that occurs in spinal cord as well as brain

ependymoma

8

Primary CNS lymphomas occur mostly in what patients?

immunocompromised

9

Severity of meningioma

benign; resection curative

10

acoustic neuroma presentation

8th cranial nerve
progressive unilateral hearing loss
may also compress CN VII
Surgical excision curative

11

Effects of pituitary tumors

HA, visual field defects, variable hypopituitarism

12

Main example of Schwannoma (or neuroma)

vestibular Schwannoma; aka acoustic neuroma

13

Common brain metastatic diseases

Lung (most common), breast, melanoma, renal, colon

14

Neurofibromas

benign peripheral nerve tumors composed of Schwann cells and fibroblasts

sx: cafe au last spots, rubbery cutaneous tumors

15

Morton's neuroma

neuroma of plantar nerve at metatarsal head
