Guillain-Barre syndrome (GBS) and Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) are inflammation polyradiculitis with peripheral nerve demyelination. We present the dissimilarity of Magnetic Resonance findings of these diseases, and relation of clinical symptom / therapy effect and image changes. Abnormal Gd-enhancement of cauda equina, especially ventral roots predominant enhancement reflects motor nerve disturbance. In GBS, abnormal enhancement effect declines after improvement of symptom. In CIDP, abnormal enhancement does not relate to symptom improvement. Furthermore, high signal intensity of cervical cord nerve root / brachial plexus on Short TI inversion recovery (STIR) images is characteristic findings of CIDP. The extent of abnormal signal intensity agreed with nerve conduction velocity delay. Swelling of cervical nerve is recognized only in a long-term affection CIDP patient. In acute stage, abnormal high signal intensity of cervical spinal nerves on STIR is dissimilarity between GBS and CIDP.
Guillain-Barre syndrome (GBS) and Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) are inflammation polyradiculitis which cause demyelination to the peripheral nerve, and autoimmunization is supposed as etiology. We present about the dissimilarity of Magnetic Resonance (MR) findings of these disease, and relation of clinical symptom / therapy effect and image changes.
