Question

These two Ethiopian boys present with “back problems”.  What are the diagnoses and what do you need to worry about with each of them?

 

 

Answer

The boy on the left has spinal tuberculosis (Pott's Disease) while the one on the right has severe scoliosis.

Pott's Disease:

  • Kyphosis caused by anterior vertebral body "wedging", usually in the thoracic spine
  • Most commonly causes motor deficits (usually leg weakness) and pain
  • Patients generally do not need respiratory isolation unless concurrent pulmonary TB is suspected.
  • Diagnosis: imaging, surgical biopsy and culture
  • Treatment: decompressive surgery for neurologic deficits and anti-TB chemotherapy

Severe Scoliosis:

  • Caused by lateral displacement and rotation of inact vertebral bodies (thus can lead to kyphoscoliosis)
  • Can cause severe respiratory impairment through decreased chest wall compliance, decreased lung compliance (due to progressive atelectaisis), and pulmonary hypertension
  • Diagnosis: clinical, imaging
  • Treatment: Pulmonary dysfucntion, once it occurs, is considered irreversible. Surgery may prevent further worsening.

Bottom Line:

Spinal tuberculosis most commonly causes anterioposterior (AP) deformity and can cause severe neurologic deficits. Anti-TB medication is needed for treatment.

Severe scoliosis involves lateral as well as AP deformity and can cause severe pulmonary dysfunction.
