Tuberculous tenosynovitis of the flexor tendons of the wrist: MR imaging with pathologic correlation

Tubercular Tenosynovitis of Extensor Tendon of Wrist Mimicking a Ganglion

“…In contrast to acute suppurative infection, TB of tendon results in lesser fluid collection [13]. Pyogenic granuloma, sarcoidosis, rheumatoid arthiritis and foreign body granuloma form important differential diagnosis [14].…”

“…Granulomas are characteristic but not definitive feature of tuberculosis. Rice bodies or melon seeds represent tubercles and are seen in about 50% cases of tuberculosis [12][13]. Routine laboratory investigations are non specific and often non contributory.…”

Extensors tenosynovitis of wrist with rupture of extensor digitorum: rare presentation of tuberculosis

“…5,[9][10][11] Although granulomas (Caseating and non-caseating) occur in most cases "Rice bodies" or "Melon seeds" represent fibrinousmasses (Tubercles) which are present in 50% of TB cases. 11,12 Laboratory findings are generally negative, except for the erythrocyte sedimentation rate, which is usually increased. 4 MRI may show thickening of the synovial membrane with increased vascularization, fluid within the tendon sheath, reactive inflammation around the tendon, or swelling of the tendon.…”

“…In contrast to acute suppurative tenosynovitis, where synovial sheath fluid is the predominant feature, relatively little synovial sheath fluid is characteristic of tuberculous pathology. 3,12 The main problem remains the difficulty in diagnosing the disease because of non-specific clinical signs that point to a number of other possibilities. Differential diagnoses of tuberculous tenosynovitis include other mycobacterial infections, pyogenic infection, brucellosis, foreign body tenosynovitis, sarcoidosis, rheumatoid arthritis, gouty arthritis, pigmented villonodular synovitis of the tendon sheath, and fungus infection.…”

“…Differential diagnoses of tuberculous tenosynovitis include other mycobacterial infections, pyogenic infection, brucellosis, foreign body tenosynovitis, sarcoidosis, rheumatoid arthritis, gouty arthritis, pigmented villonodular synovitis of the tendon sheath, and fungus infection. 5,[11][12][13] The most effective treatment involves a combination of medical and surgical therapies. 5,6,10,11 Rifampicin, isoniazid, pyrazinamide, and ethambutol are prescribed.…”
