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.

43-year-old male suffered of cervical disc herniation, and therefore C5-6 and C6-7 discectomy and fusion were done. About one year later he experienced acute sciatica followed by hot pricking sensation in the arm and neck. MRI showed far lateral bulge of L3-4 on the left and small disc bulge on C4-5, and a larger C5-6 disc herniation. Neurological examination disclosed C6-C7 radiculopathy on the left, minimal weakness of biceps and triceps muscles and reduced biceps reflex. EMG and physical examination were consistent with bilateral radiculopathy, attributed to small disc herniation.

47-year-old female with a diagnosis of Multiple Sclerosis ,who suffers from progressive tetraparesis, more pronounced in the lower extremities. Her treatment included mitoxantrone and Interferon-beta treatment, both were discontinued because of side effects. Her movement difficulties, due to the left lower limb rigidity, are increasing progressively.

78-year-old female with history of diabetes, and meningioma complicated by neurologic deficits following surgery, was diagnosed with progressive iodine-refractory metastatic papillary thyroid carcinoma (PTC). Her initial work-up revealed lung metastasis. She underwent a right thyroidectomy and then left thyroidectomy and laryngectomy, and subsequently received I-131 on 8 occasions. She had a drop in thyroglobulin levels to the early treatments, but most recently, thyroglobulin has steadily increased.
