Successful surgical treatment of scoliosis secondary to Guillain-Barré syndrome: Case report.

Guillain-Barré syndrome (GBS) is an acute autoimmune inflammatory demyelinating polyneuropathy that mostly affects the peripheral nervous system. Little is reported about spinal deformity associated with GBS.

Introduction

Guillain–Barré syndrome (GBS) is an acute autoimmune inflammatory demyelinating polyneuropathy that mostly affected the peripheral nervous system.[ GBS is clinically characterized by progressive symmetrical weakness of limbs, with or without autonomic or sensory disturbances.[ The worldwide incidence of GBS is 1.2 to 3 cases per 100,000.[ GBS may be induced by various factors, such as immunization, infection, trauma, or surgery.[ The pathogenesis of GBS was that neural antigens were cross-reactivated with antibodies to infections including cytomegalovirus, Hemophilus influenzae, Mycoplasma pneumonia, and herpes simplex.[ In this study, we reported a case of GBS in a 14-year-old patient with scoliosis.

Case report

We present a 14-year-old patient admitted for a correction of his progressive scoliosis deformity. His spinal plain radiographs showed that the Cobb angle of thoracic scoliosis was 114° (Fig. 1), suggesting the need for surgical correction.

His medical history included the diagnosis GBS at the age of 9. He complained about profound lower extremity weakness and numbness after catching a cold. One week later, pain and weakness in the lower limbs, unsteady gait, and the inability to stand up from squatting position unassisted, developed, and progressed. The diagnosis of GBS was confirmed in the local hospital. The patient received treatment with intravenous immunoglobulin and steroids. He showed significant recovery in strength in lower extremities after 2 weeks of treatment.

Two years later, the patient presented to the spinal service complaining of asymmetry of his shoulders. The deformity progressed over 1 year. His spinal plain radiographs showed that the Cobb angle of thoracic scoliosis was 114°, suggesting the need for surgical correction. Computed tomography revealed no vertebral body deformities. Magnetic resonance imaging revealed that cavernous hemangioma in the T4 (Thoracic 4) level of the spinal cord (Fig. 2). Therefore, cavernous hemangioma resection was performed in the Department of Neurosurgery of our hospital and histological examination confirmed the diagnosis of cavernous angioma.

Magnetic resonance imaging revealed that spinal-cord cavernous hemangioma in the Thoracic 4 level of the spinal cord.

Three months after the cavernous hemangioma resection surgery, a posterior correction and fusion at T5 (Thoracic 5)–L5 (Lumbar 5) levels was performed, using the LEGACY spinal system (USA). The total operation time was about 4 h. Total amount of blood loss was 1200 mL and the amount of autologous blood transfusion was 650 mL. During the operation, the signal of this patient was normal using intraoperative spinal cord monitoring. Postoperative plain X-ray film demonstrated a Cobb angles correction from 114° to 45° (correction rate 60.5%) (Fig. 3). His follow-up was symptomatic, well balanced in the coronal planes, with solid fusion (Fig. 4) 12 months after the operation.

Discussion

GBS is an acute postinfectious autoimmune polyneuropathy, characterized by rapidly progressive, areflexia, and symmetrical limb weakness.[ The diagnosis of GBS depends on the clinical features including rapid development of areflexia, muscle paralysis, and albuminocytologic dissociation of cerebrospinal fluid.[ Limited reports are available on neuromuscular scoliosis.[ In this study, we reported this case of a 14-year-old GBS case with scoliosis.

In our case, lower limb pain occurred first, followed by weakness in the lower limbs, unsteady gait, and the inability to stand up from squatting position unassisted. These symptoms progressed, indicating a high possibility of GBS. The patient showed significant recovery in strength in lower extremities after treatment with intravenous immunoglobulin and steroids.

Some patients may develop neuromuscular complications such as neuromuscular scoliosis after acute onset of GBS.[ In this case, the patient presented to the spinal service with asymmetry of shoulders 2 years after the onset of GBS. The deformity progressed over 1 year. These clinical features suggested the necessary of surgical correction. As far as we know, there is no specific guideline for operations on patients with scoliosis secondary to GBS. The onset of GBS with scoliosis could follow elective spine surgery. The present case described a successful surgical management of a rapidly progressive scoliosis with contemporary posterior surgical instrumentation and fusion.

In conclusion, GBS is a relatively rare syndrome described in recent years. Doctors must keep in mind that neuromuscular scoliosis could develop secondary to GBS. When evaluating patients with acute inflammatory polyneuropathy, clinical examination of the spine is essential to identify patients with neuromuscular scoliosis.
