E. multiple myeloma
F. osteoma

Answer 4

54. B. epidermoid cyst

Burg Fig. 1.96, p. 37. (Courtesy of Dr. John A. Goree, Durham, NC.) The scalloped
border and sclerotic rim are characteristic.

Question 5

A. hemangioblastoma
B. juvenile pilocytic astrocytoma
C. cysticercosis
D. medulloblastoma

Answer 5

55. C.cysticercosis

CNBR Fig. 3-32B, p. 184. The smooth and thin-walled intraventricular cyst
with a mural nodule is classic for cysticercosis.

Question 6

A. fetal origin of the posterior cerebral artery
B. moyamoya disease
C. persistent acoustic artery
D. persistent hypoglossal artery
E. persistent trigeminal artery

Answer 6

56. A. fetal origin of the posterior cerebral artery

CNBR Fig. 1-5. A fetal origin of the posterior cerebral artery from the internal
carotid circulation is seen in about 20% of anatomic dissections.

Question 7

A. corpus callosum lipoma
B. craniopharyngioma
C. giant aneurysm
D. glioblastoma multiforme
E. growing skull fracture

Answer 7

57. A. corpus callosum lipoma

CNBR Fig. 3-127A. Peripheral calcification is common in these lipomas.

Question 8

A. cysticercosis
B. infarct
C. low-grade astrocytoma
D. mycotic aneurysm
E. neurocytoma

Answer 8

58. A. cysticercosis

CNBR Fig. 3-32A. A small ring-enhancing lesion surrounded by a zone of low
density is typical of cysticercosis.

Question 9

A. multifocal glioblastoma multiforme (GBM)
B. multiple sclerosis
C. metastatic carcinoma
D. neurocytoma
E. tuberous sclerosis

Answer 9

59. E. tuberous sclerosis

CNBR Fig. 3-176A. Shown are giant-cell subependymal astrocytomas of tuber-
ous sclerosis. These hamartomatous lesions in the subependymal region are
sometimes called “candle guttering.”

Question 10

A. ganglioglioma
B. S. aureus
C. herpes simplex virus
D. lymphoma

Answer 10

60. C. herpes simplex virus

CNBR Fig. 3-36C, p. 189. The inflammation of the mesial temporal lobe with
diffuse edema is most characteristic of herpes encephalitis. There is often
associated hemorrhage.

Question 11

A. aqueductal stenosis
B. brainstem astrocytoma
C. Chiari malformation
D. pituitary tumor
E. polymicrogyria

Answer 11

61. B. brainstem astrocytoma

CNBR Fig. 3-66A. Diffuse enlargement of the pons is seen.

Question 12

62. This patient is most likely to presen
    A. congestive heart failure
    B. fever and chills
    C. headaches
    D. hemiparesis
    E. subarachnoid hemorrhage
    with

Answer 12

62. C

CNBR Fig. 140B. The signal intensity of colloid cysts is variable on either TI- or T2-weighted MRI. Short TI values (hyperintense images) reflect proteinaceous material. These masses arise from the anterior roof of the third ventricle.

Question 13

A. arteriovenous malformation (AVM)
B. cavernous hemangioma

C. GBM

D. metastatic carcinoma
E. tuberculoma

Answer 13

63.B. cavernous hemangioma

CNBR Fig. 3-235D. The dark halo of decreased signal is caused by iron in hemosiderin in this T2 weighted MRI. This is an almost diagnostic image of a cavernous hemangioma.

Question 14

A. astrocytoma
B. Chiari malformation
C. diskitis
D. metastatic disease
E. syringomyelia

Answer 14

64.A. astrocytoma

CNBR Fig. 3-267A. The diffuse fusiform widening of the cord with variable signal intensity is consistent with a diffuse or fibrillary astrocytoma.

Question 15

Associated with all but:

A. Renal cell Carcinoma

B. Ash-leaf macules

C. Shagreen Patches

D. Cardiac Rhabdomyoma

Answer 15

65A. Renal cell Carcinoma

CNBR Fig. 3-53B, p. 207. The enhancing intraventricular mass near the foramen of Monro is a subependymal giant-cell astrocytoma that is associated with tuberous sclerosis. The right ventricular calcified mass is a subependymal tuber. Renal cell carcinoma is associated with von Hippel Lindau syndrome.
