- 9.A 67-year-old man complains of persistent throat pain. He experiences a sharp pain in his throat and at the base of his tongue when he chews and swallows. The man does not have an infected throat and the pain is not elicited by stroking the tongue, face, or walls of the oral cavity. On some occasions the pain radiates to the man’s ear. MRI/MRA reveals that there are no obviously abnormal vessels around the brainstem. This man is most likely suffering from which of the following?
- A.

- B.
Glossopharyngeal neuralgia
- C.
Occipital neuralgia
- D.

- 10.A 43-year-old woman presents with persistent headache. She complains that her pain has waxed and waned and her discomfort has not been relieved by OTC medications. MRI reveals alarge aneurysm (3.0 cm in diameter) extending caudally from the junction of the left A1 segment and the anterior communicating artery. Based on the location and size of this aneurysm, which of the following symptoms might this patient have?
- A.
A constricted pupil
- B.
Diplopia
- C.
Idiopathic pain on the face
- D.
Partial loss of eye movement
- E.
Partial loss of vision

- 12.A 69-year-old man presents with headache. During the course of the neurological examination, the physician notices that the man’s right pupil is dilated and that his right eye deviates “down-and-out. “Which of the following represents the most likely location of this lesion?

- E.
Trochlear nerve in the interpeduncular cistern(F)Trochlear nerve in the ambient cistern
- 13.A 21-year-old man is brought to the emergency department from the site of a motorcycle collision. The neurological examination reveals that he is unable to abduct his left eye, but all other eye movements are normal. The examination further reveals that motor, sensory, and reflex function is normal. Which of the following represents the most likely location of this lesion?
- A.
Abducens nucleus on the left
- B.
Abducens nucleus on the right
- C.
Abducens root on the left
- D.
Abducens root on the right
- E.

- 14.A 27-year-old woman presents to her physician with the main complaint of double vision. The woman explains to her physician that she has had double vision on three occasions over the last several months. The examination reveals the following. When the woman looks to the right her right eye abducts and her left eye adducts. When she looks to the left her left eye abducts and her right eye does not adduct (it does not move to the right).Further evaluations suggest that this woman has MS. Recognizing the above deficits, which of the following represents the most likely location of the lesion in this woman?
- A.
Abducens nucleus on the left
- B.
Abducens nucleus on the left
- C.
Left medial longitudinal fasciculus
- D.
Left oculomotor nucleus
- E.
Right medial longitudinal fasciculus
