Tubercular meningitis occurs in around 10% of those with extrapulmonary tuberculosis and is a major cause of mortality and morbidity. Inspite of effective Anti-tubercular drugs, still around 30% of patients develop complications due to arachnoiditis such as spinal tubercular radiculomyelitis, optico-chiasmatic arachnoiditis, development of new tuberculomas after starting therapy etc. which are probably immune mediated inflammatory responses due to paradoxical reaction to ATT. The management of arachnoiditis is far from satisfactory. High dose methylprednisolone, intrathecal hyaluronic acid, thalidomide have been tried in small case series and case reports. However, the results have not been satisfactory. There are two published reports of cyclophosphamide usage in TBM related vasculitis and stroke The investigators tried cyclophosphamide in four patients after consent, and found remarkable improvement in all of them. (Under peer review) In order to test this hypothesis, a randomized controlled trial is needed.
