Tuberculous Cellulitis in a Child Demonstrated by Magnetic Resonance Imaging

Abstract

The increasing prevalence of extrapulmonary tuberculosis means that it is important for clinicians to review their knowledge of unusual presentations of mycobacterial infections. Involvement of subcutaneous tissue and skeletal muscle is rare in tuberculosis. Occasionally, infection of soft tissue may be the sole manifestation of tuberculosis. Apart from cases of tuberculous lymphadenitis, the diagnosis of extrapulmonary tuberculosis may be difficult. Modern imaging techniques, such as magnetic resonance imaging, may be helpful in making a differential diagnosis. We present here a case of tuberculous cellulitis in an immunocompetent child and discuss the contribution of MRI in diagnosis.
