Multiple osteomyelitis due to Mycobacterium avium with no pulmonary presentation in a patient of sarcoidosis.

A 31-year-old man with multiple osteomyelitis due to Mycobacterium avium is reported. The patient had been on prednisolone for systemic lymphadenopathy which was thought to be caused by sarcoidosis. In June 1990, he noticed high fever and general bone pain. He was found to have multiple lytic lesions in the bones which were biopsied showing acid-fast bacilli. This organism was revealed to be M. avium. The chest radiograph film revealed no abnormal pulmonary findings. Multiple bone lesions in the absence of pulmonary disease is reported to be rare for atypical mycobacterial infection.
