Disseminated Mycobacterium interjectum Infection with Bacteremia, Hepatic and Pulmonary Involvement Associated with a Long-Term Catheter Infection

Abstract EN

We present a 49-year-old female with one year of intermittent fevers, chills, night sweats, and significant weight loss.

Liver and lung biopsy showed evidence of a granulomatous process.

Blood and liver biopsy cultures yielded growth of presumed Mycobacterium interjectum, thought to be related to a disseminated long-term central venous catheter infection.

She successfully received one year of combined antimicrobial therapy after catheter removal without recurrence of disease.

M.

interjectum has been previously described as a cause of lymphadenitis in healthy children and associated with pulmonary disease in adults, although other localized infections have been reported.

This is the first case described of a disseminated M.

interjectum infection with bacteremia, hepatic and pulmonary involvement associated with a long-term catheter infection.
