Session Description
A previously healthy 10-year-old immunocompetent male, who had immigrated from Morocco to Canada presented with a left parasternal mass that started small and grew quickly to the size of a tennis ball within 2 months. He had excisional biopsy, and the specimen from the excisional biopsy was PCR positive for Mycobacterium Tuberculosis. Patient was diagnosed with Diseminated Tuberculosis and started on Rifampin, Isoniazid, Ethambutol and Pyrazinamide regimen.
Chest wall TB is a diagnostic challenge. Its presumed to occur by hematogenous route and by direct extenson through the chestwall lymhatics. Clinicians need to be aware and consider it the differential dignosis of a Chest wall mass especially in recent immigrants from TB endemic regions. Anti TB treatment and adjuvant surgery have been shown to be effective in treatment of chest wall TB in case reports.
