Combined ulnar and median nerve compression due to atypical mycobacterial tenosynovitis: case report

A 39-year-old woman with signs, symptoms and laboratory findings of carpal tunnel syndrome and ulnar compression is presented. Radical surgical debridement, excision of the affected synovium and early postoperative mobilization were performed. Mycobacterium marinum was identified from the culture of the excised flexor tenosynovium. Neither pulmonary nor extrapulmonary tuberculosis was diagnosed by X-ray and the other laboratory examinations. There has not been any previously reported case of mycobacterial tenosynovitis causing ulnar and median nerve compression together.
