A. arachnoid cyst
B. Dandy-Walker malformation
C. epidermoid cyst
D. porencephaly
E. vein of Calen aneurysm
B. Dandy-Walker malformation
A hypoplastic vermis, high transverse sinus, and cystic dilatation of the fourth ventricle are characteristic of the Dandy-Walker malformation
A. arachnoid cyst
B. ependymoma
C. lipomyelomeningocele
D. meningioma
E. neurenteric cys
C. lipomyelomeningocele
A subcutaneous lipoma that extends into the low-lying tethered spinal cord is seen.
The patient whose myelogram is shown probably
A. has developmental cysts
B. has multiple cafk au lait lesions
C. is asymptomatic
D. was recently diagnosed with lung cancer
E. was thrown from a motorcycle
E. was thrown from a motorcycle
The classic appearance of pseudomeningoceles from
lower cervical nerve root avulsion is seen in this myelogram.
A. AVM
B. carotid occlusion
C. dural AVM
D. meningioma
E. moyamoya disease
D. meningioma
This lateral venous phase angiogram shows the tumor stain of a convexity meningioma
A. glioblastoma
B. lymphoma
C. Fahr’s disease
D. herpes simplex virus
B. lymphoma
Bilateral periventricular enhancing masses are
most consistent with lymphoma. They usually enhance quite brightly. Fahr’s disease is idiopathic basal ganglia calcification and should be low-intensity on
MRI. Herpes simplex virus (HSV) infection usually involves the temporal Lobes. Glioblastoma may be multicentric, but this picture is most likely a lymphoma.
A. disk herniation
B. epidural abscess
C. meningioma
D. metastatic disease
E. radiation chang
B. epidural abscess
An epidural infection is iso- or hypointense to the cord
on TI-weighted, and hyperintense on R-weighted and proton density unenhanced MRls. With contrast, the solid portion of the abscess or the periphery
of a liquid collection enhances
The lesion shown is associated with
A. Ehlers-Danlos disease
B. endocarditis
C. fibromuscular dysplasia
D. radiation therapy
E. renal cysts
E. renal cysts
Cerebellar hemangioblastomas (tumor stain is seen in this arterial phase) are associated with renal and pancreatic cysts
A. dural AVM
B. moyamoya disease
C. sagittal sinus thrombosis
D. subdural hematoma
E. vein of Calen aneurysm
E. vein of Calen aneurysm
Lateral basilar angiogram shows early filling of the vein of Galen. Vein of Galen aneurysms usually present with high-output cardiac failure
in the neonate. They also may present with hydrocephalus in the infant, or sub-
arachnoid hemorrhage, epilepsy, or mental retardation in the older child (adult).
A. chordoma
B. diskitis
C. metastatic disease
D. neurofibroma
E. normal lumbosacral radiograph
B. diskitis
Erosion of the inferior anterior L5 end plate is noted. Plain film abnormalities in diskitis may not become evident for weeks. They include
irregularities of the end plate, loss of disk space height, and bony sclerosis
A. human immunodeficiency virus (HN)
B. glioma
C. rapid correction of hyponatremia
D. methotrexate toxicity
C. rapid correction of hyponatremia
Central pontine myelinolysis is associated with the
rapid correction of hyponatremia and usually occurs in malnourished or alcoholic patients.
The etiology of the process shown is
A. developmental
B. iatrogenic
C. infectious
D. neoplastic
E. traumatic
A. developmental
. This CT shows the bony spur of diastematomyelia. Each hemicord is enclosed in its own dural sheath
A. AVM
B. fusiform aneurysm
C. misplaced shunt catheter
D. schizencephaly
E. venous malformation
E. venous malformation
This 8-year-old boy who presented
most likely to Rave a(n)
A. astrocytoma
B. Dandy-Walker cyst
C. hemangioblastoma
D. medulloblastoma
E. metastatic tumor
with headaches, nausea, and vomiting is
A. astrocytoma
A. acoustic neuroma
B. chordoma
C. giant-cell tumor
D. glomus jugulare
E. meningioma
D. glomus jugulare
The heterogeneous “salt and pepper” appearance of
the glomus jugulare tumor is appreciated. These relatively rare tumors arise
from rests of paraganglionic tissue along the jugular bulb. Glomus typanicum tumors occur in the middle ear
A. no intervening normal brain
B. usually multiple
C. often associated with cavernous malformation
D. frequently hemorrhage
C. often associated with cavernous malformation
Venous malformations consist of a large draining
cortical vein receiving a collection of medullary veins (caput medusae). There usually is intervening normal brain, unlike with arteriovenous malformations
(AVMs) and capillary telangiectasias. They are usually single, unlike capillarytelangiectasias. They rarely hemorrhage and are often found along with
cavernous malformations
