A. arachnoid cyst
B. Dandy-Walker malformation
C. epidermoid cyst

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. 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.

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

Cerebellar hemangioblastomas (tumor stain is seen in this arterial phase) are associated with renal and pancreatic cysts

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).

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

C. rapid correction of hyponatremia

Central pontine myelinolysis is associated with the
rapid correction of hyponatremia and usually occurs in malnourished or alcoholic patients.

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
