Acute flaccid paraplegia: a rare complication of meningococcal meningitis.

STUDY DESIGN

A case report of spinal cord dysfunction following meningococcal meningitis.

OBJECTIVES

To describe a rare complication of meningococcal meningitis.

SETTING

Spinal Unit, Armed Forces Institute of Rehabilitation Medicine, Rawalpindi, Pakistan.

METHODS

A young healthy male developed meningococcal meningitis followed by acute onset low thoracic flaccid paraplegia with complete motor and sensory loss and sphincter disturbance. He responded well to antibiotics but was not investigated for causes of paraplegia. While at home in a rural area, he developed pressure ulcers, anemia and depression. Magnetic resonance imaging of the whole spine and computed tomography scan of the brain performed after 4 and 10 weeks were normal.

RESULTS

The patient had a comprehensive rehabilitation at our institute. Recovery was complicated by ossification in the right thigh, which responded well to radiotherapy. At 1-year follow-up, the motor deficit and neurogenic bladder and bowel persisted and the patient remained wheelchair dependent for mobility.

CONCLUSION

Several mechanisms have been proposed to explain spinal cord damage after meningitis. These include spinal cord infarction; autoimmune-mediated inflammatory myelopathy and direct infection of the cord. Most probable cause of spinal cord dysfunction in this case was thoracic myelopathy.
