66-year-old male with a 6-year history of sensory symptoms in the feet and hands. He describes a sensation of cold and stinging in the feet; and numbness in the hands, especially at night. Nerve conduction and EMG demonstrated axonal and demyelinative sensorimotor neuropathy with neurogenic changes in muscles. Follow-up nerve conduction testing that was performed 2 years later showed similar findings.
21-year-old female with an acute onset of a unilateral sixth cranial nerve deficit. Brain MRI showed at least a dozen white matter lesions, one of them contrast-enhancing. Sensory evoked potentials showed a bilateral increase in latency. Multiple sclerosis was diagnosed, and the patient was treated by corticosteroids, followed by improvement of symptoms. The first follow-up revealed no focal neurological signs with a history of a transitory unilateral lower limb hyposthenia. On the second visit, a horizonto-rotatory nystagmus and irregular paraesthesia in the right toes are documented.
45-year-old male who presented with acute onset of flaccid paraparesis more pronounced on the left, sensation of current shocks in both legs and sensory level from the umbilicus downwards. The symptoms have reached their pick within less than a day. On examination the left lower limb was plegic and the right lower limb was partially weak. EMG was interpreted as demyelinating sensorimotor neuropathy. MRI showed hyperintense signals at the dorsal terminal segment of the marrow consistent with myelitis.
