Article Synopsis
  • Extrapulmonary tuberculosis (EPTB) can present in various ways, but isolated bone infections are rare and often confused with other conditions like chronic pyogenic osteomyelitis or tumors.
  • This case describes an unusual instance of tuberculous osteomyelitis that presented similarly to acute monoarthritis in the wrist, which is not commonly reported.
  • The findings highlight the need for clinicians to consider EPTB as a potential diagnosis even when symptoms don't match typical tuberculosis presentations.
