53-year-old male with lower motor neuropathy affecting all 4 limbs. The neurologic examination showed left limb hyposthenia, left upper limb hypotrophy and diffuse fasciculations. The patient was diagnosed with “suspect motor neuron disease" and was treated with IVIG cycles with slight initial improvement, but later lack of response and worsening of the clinical condition.

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.

52-year-old male with a one year history of lower motor neuropathy affecting the limbs, left upper and lower limbs clinically and all 4 limbs electrically. The neurologic examination showed left lower and left upper limb hyposthenia with mainly distal motor clumsiness, appearance of left upper limb hypotrophy and diffuse fasciculations. The patient was diagnosed with “suspect motor neuron disease" and was treated with IVIG cycles with slight initial improvement, but later lack of response and worsening of the clinical condition.
