Recurrent Carpal Tunnel Syndrome Associated with Mycobacterium szulgai Infection: A Case Report.

ABSTRACT

CASE We present the case of an otherwise healthy 77-year-old male retired firefighter and recreational pheasant hunter who presented with recurrent symptoms of carpal tunnel syndrome and tenosynovitis because of Mycobacterium szulgai. He was initially treated unsuccessfully for a presumed seronegative rheumatologic flare, followed by surgical diagnosis and treatment including revision carpal tunnel release with tenosynovectomy, and a secondary debridement and wound closure. His symptoms resolved after several months of multidrug antibiotic therapy with only mild residual median nerve deficit. CONCLUSION: Nontuberculous Mycobacterium infections of the upper extremity are extremely rare and challenging to diagnose/treat. This report highlights diagnostic and surgical challenges in this rarely reported infection.
