This case reported a young man in whom deafness was the sentinel event leading to the discovery of pulmonary tuberculosis and molecular confirmation of concurrent TOM.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>\n                      A 23-year-old male presented with bilateral, progressive hearing loss that had been labeled \u201cchronic suppurative otitis media\u201d by local clinics. Persistent constitutional symptoms prompted chest imaging that revealed bilateral cavitary infiltrates.

After transfer to our tuberculosis center, targeted NGS of serous middle-ear fluid detected MTBC; the isolate carried an rpsL K43R mutation conferring streptomycin resistance, identical to the pulmonary strain. Standard four-drug anti-tuberculosis therapy was initiated; within 4\u202fweeks, cough and fever resolved, inflammatory markers normalized, and the pulmonary cavity showed reduction in size compared to baseline.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This case highlights that unexplained hearing loss may serve as an early indicator of disseminated tuberculosis.
