46. A 13-year-old boy is brought to the physician
by his mother
because of frequent headaches over the past 5 weeks.
He describes the
headaches as dull pain across his forehead; they occur
four to five times
weekly. Acetaminophen does not relieve the pain. His
mother states
that occasionally he has nausea without vomiting. He
has schizophrenia
well controlled with risperidone. Physical
examination shows no
abnormalities. An MRI of the brain is most likely to
show which of the
following?
A
) Bilateral increased caudate nuclei
B
) Decreased cerebellar volume
C
) Hippocampal symmetry
D
) Increased lateral ventricle size
E
) Multiple white-matter hyperintensities
