INTRODUCTION: Optic neuromyelitis or Devic's syndrome is a very rare disease affecting the optic tracts and the spinal cord. Its association with evolving pulmonary tuberculosis has been reported in a handful of case reports. CASE REPORT: The authors report two cases of Devic's syndrome associated pulmonary tuberculosis (48 and 43 years old men). The First patient was experiencing evolving pulmonary tuberculosis. The two patients were admitted for bilateral blindness followed by paraplegia and sphincter disturbance. Clinical examination and investigations excluded direct tuberculous involvement of the nervous system or a reaction to antituberculous therapy and Devic's syndrome was diagnosed, based on Wingerchurk's criteria. Following treatment with corticosteroids and antituberculous chemotherapy, we noted partial recovery of motor symptoms and sphincter control but the patients remained completely blind. CONCLUSIONS: Throughout this case report, the authors emphasize the rarity of this association and discuss the pathophysiological mechanism, which appears to be an immune dysfunction triggered by mycobacterium infection.
