Identifying this phenomenon is crucial, since it can be mistaken with treatment failure or relapse. Although widely described in HIV patients following immune reconstitution inflammatory syndrome, the literature on HIV\u2010negative patients is scarce.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Case Series:<\/jats:bold>\n                    We present three cases of immunocompetent patients with central nervous system tuberculosis (CNS\u2010TBC) who developed paradoxical reactions following appropriate TBC therapy. These included diverse clinical and radiological manifestations, such as persistent headaches, apparition or progression of tuberculomas, cerebral infarcts, and dorsal myelitis. Paradoxical reactions occurred within an average of 2.5\u2009months from the start of anti\u2010TBC treatment.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusion:<\/jats:bold>\n                    Our findings underscore the importance of closely monitoring patients following anti\u2010TBC treatment to identify potential complications rapidly.
