Aside from some difficulty swallowing, she has no ocular, bulbar, or sphincter problems and no sensory complaints. Family history is negative for neurological disease. Examination reveals significant proximal limb and neck muscle weakness with minimal atrophy, normal sensory findings, and normal deep tendon reflexes.

Which of the following is the most likely diagnosis in this patient? 

a. Polymyositis
b. Cervical myelopathy
c. Myasthenia gravis
d. Mononeuritis multiplex
e. Limb-girdle muscular dystrophy

Where is the responsible lesion?

b. Left cerebral hemisphere
c. Right side of the brainstem
d. Left side of the brainstem

A 26-year-old woman presents for follow-up of her multiple sclerosis. She has had two separate episodes of optic neuritis and has noticed stutteringly progressive weakness in her lower extremities. She has a mild neurogenic bladder. Her symptoms have been stable over the past 4 months. MRI scanning reveals several plaques in the periventricular white matter (MR scan shown here) and several other plaques in the brainstem.

What is the best next step in her management?

a. Intravenous methylprednisolone 1 g daily for 3 days
b. Oral cyclophosphamide
c. Oral anticholinergics for the urinary incontinence and observation of the demyelinating process
d. Interferon-beta

She develops urinary urgency and frequency and is treated with oxycodone and ciprofloxacin. Three days later she develops a headache, dizziness, vomiting, and has difficulty walking. On neurological examination her strength, sensation (including vibratory sensation), and reflexes are normal. She walks with an uncoordinated, unsteady gait. On testing of coordination in the upper extremities, she displays past-pointing and poor rapid alternating movements with her right upper extremity. In the lower extremities, her heel-shin testing also reveals poor coordination on the right. INR is 6.5 (normal < 1, therapeutic for warfarin 2.0–3.0).

What is the most likely cause of her neurologic findings? 

a. Right cerebellar hemorrhage
b. Multiple small infarcts in the basal ganglia
c. Adverse effects of oxycodone
d. Alcohol abuse
e. Posterior column degeneration as a result of vitamin deficiency
