|
Term
| Originates from dura mater or arachnoid, and compresses adjacent structures, causing AMS. Common with advancing age. Usually benign; treatment is surgical. |

Definition
|
|
Term
| Malignant, rapidly-growing cystic, pulpy tumor. Common adult brain tumor that has pseudopod-like projections. Prognosis is very poor, and you can't totally remove it. |
|
Definition
|
|
Term
| Much like a glioblastoma, but course is more drawn out and benign. Surgical resection usually not possible by the time it's caught, but may be radiosensitive/chemosensitive. |
|
Definition
|
|
Term
| Seen most frequently in children, arising from the roof of the 4th ventricle. Leads to increased intracranial pressure accompanied by brainstem and cerebellar signs. Txt is surgery combined with radiation/chemotherapy. |
|
Definition
|
|
Term
| Glioma arising from the ependyma (epithelial layer) of a ventricle (esp. 4th). Increased ICP. Best treated surgically, and radiation doesn't really work. |
|
Definition
|
|
Term
| Slow-growing, and usually arises in cerebral hemisphere in adults. Calcification seen on skull radiograph. Treatment is surgical and usually successful. |

Definition
|
|
Term
| Usually presents during childhood with cranial nerve palsies and then long tract signs in the limbs. ICP occurs late. Inoperable - txt is by irradiation and a shunt. |

Definition
|
|
Term
| Presents with disequilibrium, ataxia of trunk/limbs, and signs of ICP. Can be familial. Txt is surgical. |

Definition
| Cerebellar hemangioblastoma |
|
|
Term
| Usually presents during childhood with cranial nerve palsies and then long tract signs in the limbs. ICP occurs late. Inoperable - txt is by irradiation and a shunt. |
|
Definition
|
|
Term
| Presents with increased ICP, often with impaired upward gaze (Parinaud syndrome) and other deficits suggestive of midbrain lesion. Decompression by shunting is followed by surgery. Irradiation necessary if malignant. |
|
Definition
|
|
Term
| Originates from Rathke pouch above sella turcica, depressing the optic chiasm. Also presents with endocrine dysfunction and bitemporal field defects. Usually seen in kids. Treatment is surgical. |
|
Definition
|
|
Term
| Ipsilateral hearing loss is most common first symptom. Later: tinnitus, hearing loss, vertigo, facial weakness/numbness. Tumor is surgically excised. |
|
Definition
|
|
Term
| Associated with AIDS/immunocompromised. Focal signs or disturbances of thinking/consciousness. Treatment is whole brain radiation/chemo. |
|
Definition
| Primary cerebral lymphoma |
|
|
Term
| Tumors in this region present with progressive intellectual decline, a slowing of mental activity, personality changes, contralateral grasp reflexes, Broca's aphasia, and anosmia. |
|
Definition
|
|
Term
| Tumors in this region present with olfactory/auditory hallucination seizures, licking or smacking of the lips, a decrease in awareness or consciousness, emotional and personal changes, deja vu or jamais vu, upper quadrantopia, and sometimes Wernicke's aphasia. |
|
Definition
|
|
Term
| Tumors in this area of the brain present with contralateral sensory disturbances or seizures, sensory loss (astereogenesis), lower quadrantopia, hemineglect, and thalamic syndrome (contralateral hyperpathia and spontaneous pain) if diffuse. |
|
Definition
|
|
Term
| Tumors in this part of the brain present with crossed homonymous hemianopsia or crossed visual field defect, loss of color perception, other ocular problems, and cortical blindness if bilateral. |
|
Definition
|
|
Term
| Tumors in this area of the brain present with CN palsies, ataxia, incoordination, nystagmus, and pyramidal and sensory deficits in the limbs, uni OR bilaterally. |
|
Definition
| Cerebellum/brainstem tumors |
|
|
Term
| Presentations include CN 3 and 6 palsies, as well as bilateral Babinski signs. |
|
Definition
| False localizing signs due to herniation or mass effect. |
