he  axial postcontrast MRI  shown  was  obtained  in a  patient with

A.  acquired immunodeficiency  syndrome (AIDS)
B.  Chiari malformation
C.  disk  disease
D.  neurofibromatosis
E.  severe spinal cord  trauma

A.  acquired immunodeficiency syndrom (AIDS)

Yock case  1148, p.  702.  Cytomegalovirus  (CMV)  is a frequent cause  of  polyradi-
culitis  and  myelitis in  patients  with  acquired immunodeficiency syndrome
(AIDS). The pial enhancement  seen is characteristic of  this condition.

2

A.  giant-cell tumor
B.  osteoblastoma
C.  aneurysmal bone cyst
D.  osteoid osteoma

D.  osteoid osteoma

CNBR  Fig.  3-257,  p.  343. The  lytic lesion  with surrounding sclerosis  and  a
central nidus  is classic for osteoid osteoma. These usually  present with pain
that  resolves  with aspirin.

this post contrast T1 weighted MRI illustrates

A.  abscesses
B.  gliomatosis cerebri
C.  metastatic disease
D.  multiple infarcts
E.  neurofibromatosis type  2

E. neurofibromatosis type 2

CNBR Fig.  3-175. The bilateral acoustic neuromas and  multiple meningiomas
are consistent  with neurofibromatosis  type 2.

4

This  postcontrast TI -weighted MRI illustrates a(n)

A.  aneurysm
B.  colloid cyst
C  GBM
D.  meningioma
E.  metastasis

D. meningioma

Yock case  47, p.  29. A parafalcine meningioma is shown.

5

A.  abscess
B.  artifact
C.  hemangioblastoma
D.  infarct
E.  metastasis

D. infarct

Yock case  580, p.  360. A  gyriform  pattern of  contrast  enhancement  in the
distribution of  the  left  anterocerebral artery  (ACA)  is suggestive  of  subacute
infarction

6

A.  aneurysm
B.  AVM
C.  infarct
D.  normal angiogram
E.  persistent trigeminal artery

C. infarct

Osb  1  Fig.  9-38A,  p.  283. Occlusion of  the  central sulcus  artery  is  shown.

7

A.  type II  fracture
B.  usually requires surgery
C.  requires traction
D.  treated with external  orthosis

D. treated with external orthosis

CNBR Fig.  3-298C Type I11  odontoid fractures usually heal well  with an external
orthosis (e.g.,  halo, Somi. Minerva). Type I1  fractures  will  more often require
surgical stabilization, especially if  there is  more than 6  mm  of  displacement.

8

A. abscess

B.lymphoma

C. multiple sclerosis

D. periventricular leukomalacia

E. tuberous sclerosis

B. lymphoma

Yock case  434,  p.  271.  Periventricular  involvement  by  primary  central
nervous system lymphomas is  common.

9

A.  acute infarction
B.  chronic subdural  hematoma
C.  epidermoid cyst
D.  intracranial  hypotension
E.  Sturge-Weber  syndrom

E. sturge - weber syndrom

CNBR  Fig.  180C. The layer of  enhancement  covering  the  hypoplastic  right
hemisphere represents the  meningeal angioma.
