title: Symptomatic calcifying pseudotumor of the thoracic spine that resolved with the indomethacin treatment: a case report.
abstract: METHODS
  Case report.
  
  
  OBJECTIVE
  To report a rare case of calcifying pseudotumor of the thoracic spine that resolved completely with Indomethacin treatment.
  
  
  BACKGROUND
  A 48-year-old male patient presented with a complaint of left T9 radiculopathy. Computed tomography scan and magnetic resonance images showed a calcifying pseudotumor of the thoracic spine. The nature of this disease remains unknown. This lesion behaves as a tumor-like lesion that is probably inflammatory in nature with a bone-forming potential.
  
  
  METHODS
  The patient was treated conservatively with Indomethacin 25 mg 3 times daily for 8 weeks. The lesion was monitored with computed tomography and magnetic resonance imaging at 8 weeks and at 16 weeks after initiation of treatment.
  
  
  RESULTS
  The patient had radicular pain for 8 weeks and sleep disturbance for 6 weeks prior to treatment. After he started taking Indomethacin 25 mg 3 times daily, the radicular pain resolved on the third day of Indomethacin treatment. The size of the mass reduced significantly at eighth week follow-up and resolved completely at 16 weeks of follow-up.
  
  
  CONCLUSIONS
  Calcifying pseudotumor of spine should be treated with a trial of Indomethacin before surgical option is offered, unless the patient has a significant progressive neurological deficit that requires urgent surgical intervention.
