Mycobacterium tuberculosis infrequently infects muscle. We experienced a case of tuberculous myositis complicated with usual interstitial pneumonia (UIP).
A 56 year-old male patient was admitted due to erythematous painful swelling on left proximal upper extremity and right inner thigh for 10 months. The level of serum creatine kinase, lactic acid dehydrogenase, serumglutamic oxaloacetic transaminase, serum glutamic pyruvate transaminase and aldolase were elevated. Electromyography showed low amplitude, short duration, polyphasic motor unit potentials at left biceps brachii, flexor carpiradialis longus,extensor carpi radialis longus, right adductor longus and early recruitment pattern at right biceps brachii. Muscle biopy showed the findings compatible with tuberculosis.
Interstitial lung disease was suspected on chest x0ray and high-resonance computerized tomography, UIP was confirmed by open lung biopsy. We started anti-tuberculosis medication and prednisolone for the treatment of tuberculous myositis and UIP, respectively. After 4 weeks of treatment, patient's symptoms of myositis were improved. The patient is being followed up for monitoring treatment response to prednisolone for UIP.
