They discover that while she can sit unassisted, she is unable to stand. When standing, she sways and falls forward, backward, or to one side. On a detailed physical exam, strength is 5/5 to flexion and extension at the ankle, knee, hip, shoulder, elbow, and wrist bilaterally.
Which of the following locations of the bleed best explains this finding?
Which of the following is the genetic mutation commonly seen in patients with hereditary neuropathy with liability to pressure palsy (HNPP)?
A 40-year-old male with a history of headaches, seizures, and recurrent strokes has a brain biopsy performed to aid in diagnosis. Electron microscopy of his brain tissue shows granular osmiophilic material in the basal lamina of small cutaneous arterioles. What is the cause of this patient’s disease?
A 42-year-old woman presents to the clinic with a 2-month history of distal symmetric hand weakness that started after hospitalization for severe abdominal pain. Before this hospitalization, she was drinking alcohol with her friends when she acutely developed severe abdominal pain, nausea, restlessness, altered mental status, and hallucinations. She was noted to have dark urine at the time of admission. Since then, her GI symptoms and mentation have returned to baseline, but her weakness has persisted. On exam, she has 3/5 strength of the intrinsic muscles of the hand bilaterally. Conduction velocities of the bilateral upper extremities were unremarkable. Needle EMG revealed fibrillations and decreased recruitment of motor unit action potentials in muscles innervated by the radial and ulnar nerves. Which of the following is the most likely cause of the patient’s symptoms?
A 31-year-old man presents after being found down at the scene of an armed robbery. On physical examination, there is lower extremity weakness and loss of proprioception and vibration on the right side, as well as loss of pain and temperature sensation on the left leg. His sagittal CT spine is shown below. Which is the most likely condition suffered by this man?

A 65-year-old man presents to the emergency room with progressive weakness over the course of several months. Examination shows pure motor weakness with no sensory involvement, decreased reflexes, and diffuse fasciculations. An EMG shows a conduction block of motor neurons outside of compression sites and normal sensory conduction velocities. Which of the following of most appropriate for treatment?
