Brain test Flashcards
what brain neoplasms are potentially fatal
benign brain neoplasm, metastatic brain cancer, secondary brain cancer, and primary brain cancer
what is most common lesion of brain
metastatic brain cancer
what is most common primary brain tumor
astrocytoma
what is most aggressive brain tumor
medulloblastoma
what lesions are most often malignant
astrocytoma, and medulloblastoma
what brain lesions are most likely to appear in mulitples
mets
what lesions generally grows on the periphery of brain
acoustic neuromas, and meningiomas
what lesions grows from the Schwann cell’s of the 8th cranial nerve
acoustic neuromas
what lesions are most likely to be associated with hormonal imbalances
pituitary adenoma
which lesions grow primarily in the cerebellum/posterior fossa of cranial cavity
medulloblastoma
lesions in the brain may be associated with which of these intracranial conditions
bleeding, ischemia, edema, and mass effect
ischemic stroke may be a result of arterial interruption in which vessels
basilar artery, internal carotids and cerebral arteries
which condition is the result of thrombosis or arterial stenosis
ischemic stroke
which conditions causes a permanent loss of neurologic function
hemorrhagic stroke and ischemic stroke
which condition is caused by blood extravasation in the brain
hemorrhagic stroke
which condition is also called an ‘intracranial bleed’
hemorrhagic stroke
which condition will always present in imaging as an area of infarct in the brain
ischemic stroke
which condition is most likely to be lethal
hemorrhagic stroke
which bleeds generally occur in parenchyma (substance) of the brain
intracranial bleed (ICB)
which conditions can be further defined with angiographic/contrast enhanced imaging
ischemic stroke, and subarachnoid hemorrhage (SAH)
which condition is most likely to be associated w an aneurysm
subarachnoid hemorrhage (SAH)
which conditions causes blood accumulation on the periphery of the brain
subdural hemorrhage (SDH) and epidural hemorrhage (EDH)
which conditions is almost always the result of trauma to the brain
epidural hemorrhage, and subdural hemorrhage
traumatic contusions in the brain are one form of which condition
intracranial bleed
which condition is almost always associated w a skull fx
epidural hemorrhage
what describes the appearance of a brain abscess in sectional imaging
may show areas of necrosis, often rim enhancing, and may be associated with edema
which conditions is a result of infection in the brain
meningitis, brain abscess and encephalitis
what conditions are rarely associated with bleeding in the brain
ischemic stroke and meningitis
what condition results in bleeding focused in the suprasellar cistern
subarachnoid hemorrhage
what condition may be secondary to cerebral atrophy
hydrocephalus
what is best imaged in the sagittal plane
chiari malformation
what is related to dementia and aging
cerebral atrophy
what presents as abnormal CSF collections formed by the subarachnoid membrane
arachnoid cyst
what is imaged as CSF engorgement in the ventricles
hydrocephalus
what is active lesions enhanced with contrast
multiple sclerosis
