CNS Cancer
Perivascular pseudorosettes are characteristic of this CNS cancer.
What is Ependymoma?
This type of imaging sequence shows CSF and fluids as bright.
What is Axial T2-weighted MRI?
Rotational forces applied to the brain during a torque injury damage deep brain structures, particularly this structure.
What is the reticular formation?
This fiber bundle relays information from the hippocampus to the mammillary bodies.
What is the fornix?
Locked-In Syndrome is typically caused by occlusion or damage to these vessels. (one is sufficient).
What are the basilar and anterior inferior cerebellar arteries?
This CNS cancer is associated with previous radiotherapy and neurofibromatosis type II.
What is Meningioma?
This diagnostic option does not require radiation or contrast.
What is MR angiogram?
This form of transtentorial herniation presents with ipsilateral CNIII compression and mydriasis.
What is an Uncal Herniation?
This segment of cranial gyrus connects the parahippocampal gyrus and the cingulate gyrus.
What is the isthmus?
These are the vestibular nuclei found in the pons.
What are the lateral and superior vestibular nuclei?
These are thick, eosinophilic corkscrew-shaped fingers found in Pilocytic Astrocytoma?
What are rosenthal fibers?
This technique maps the direction of water diffusion in the brain, which allows us to visualize white-matter fiber tracts.
What is Diffusion Tensor Imaging (DTI)?
These are the three components of Cushing's Triad.
What are:
Hypertension
Bradycardia
Irregular respirations?
This is the target of the optic tracts bringing information from both eyes to the thalamus.
What is the lateral geniculate body?
The cerebellar nucleus processes output from the vermis and flocculonodular lobes.
What is the fastigial nucleus?
Fried-egg cells and chicken-wire capillary networks are characteristic of this diffuse glioma.
What is oligodendroglioma?
These vessels are ruptured in a subdural hematoma.
What are bridging veins?
A low BP and a high ICP do this to CPP.
What is reduce/decrease?
Following the lateral sulcus into the parietal lobe lands you at this region that participates in language comprehension.
What is the supramarginal gyrus?
This brainstem structure receives bilateral signals from each set of cochlear nuclei, helping to localize, amplify, and filter sound.
What is the superior olive/superior olivary nucleus?
Mutations in hamartin and tuberin in Tuberous Sclerosis causes overactivation of this growth factor.
What is mTOR?
A low CBF and a low CBV indicates this.
What is infarction?
Loss of Consciousness last for this amount of time during a mild (mTBI) concussion.
What is < 30 minutes?
This is the site of dopaminergic neurons that project to the limbic structures (i.e. nucleus accumbens) for reward.
What is the ventral tegmental area?
These fibers leave the superior olives and head to the inferior colliculus.
What are the lateral lemniscus?
