What is the preferred medical imaging modality for most conditions of the central nervous system?
radiography
dual energy x-ray absorptiometry
CT
MRI
MRI
A congenital condition where there is a protrusion of both the meninges and the spinal cord into the skin of the back due to failure of the bony neural arch of the spine to completely close:
meningocele
meningomyelocele
myelocele
encephalitis
meningomyelocele
Meningocele- only the meninges protrude
Myelocele- protrusion of the spinal cord
An excessive accumulation of CSF within the ventricles that can be either congenital or acquired:
glioma
encephalitis
brain abscess
hydrocephalus
hydrocephalus
What is the most common cause of chronic meningitis?
Bacterial infections
Fungal infections
Viral infections
None of the above
Fungal infections
meningitis- inflammation of the meningeal coverings of the brain and spinal cord
encephalitis- inflammation of the brain tissue that is usually viral in nature.
An infection of the brain tissue that is usually viral in nature and may also occur subsequent to conditions such as chickenpox, smallpox, influenza, and measles.
neurofibroma
meningitis
encephalitis
schwannoma
encephalitis
neurofibroma- benign peripheral nerve sheath tumor
meningitis- An inflammation of the meningeal coverings of the brain and spinal cord. Fungal infections are the most common cause.
Unless treated with antobotics, this fatal condition is due to a trauma or infection that forms an encapsulated accumulation of pus within the cranium:
brain abcess
multiple sclerosis
myelocele
lacunar infection
brain abcess
Patients with degenerative disk disease may experience a sudden and severe onset of sensory or motor dysfunction. This is referred to as:
spondylosis
stenosis
radiculopathy
laminectomy
radiculopathy
A degenerative disease where osteoarthritic changes in the neck leads to the formation of osteophytes (bone spurs) causing stenosis and compression of the nerves; typically demonstrated with oblique cervical x-ray projections:
cervical spondylosis
hydrocephalus
ependymoma
whiplash
cervical spondylosis
A chronic, progressive disease of the nervous system that involves the degeneration of the myelin sheath covering the nervous tissue of the spinal cord and the white matter within the brain which can be seen on MRI:
subdural empyema
multiple sclerosis
cerebrovascular accident (CVA)
glioma
multiple sclerosis
A progressive degenerative disease of the brain, associated with older persons, characterized by amyloid β plaques, brain atrophy, and a decline in memory and cognitive function.
Lewy body dementia
vascular dementia
pituitary adenoma
Alzheimer disease
Alzheimer disease
A type of stroke that is caused when a blood clot blocks a blood vessel in the brain:
hemorrhagic
aneurysm
ischemic
hyperplastic
ischemic
A type of stroke that is caused when a blood vessel in the brain ruptures and bleeds into the adjacent brain tissues and structures:
hemiplegic
ischemic
infarctionism
hemorrhagic
hemorrhagic
