Volumineux abcès pottique

Osteoarticular tuberculosis was frequent throughout the world a decade ago but antituberculous chemotherapy and prophylactic measures have clearly contributed to the reduction of its frequency. However, Pott's disease is frequently complicated by an abscess and some locations are exceptional on account of their gravity. We report a case of dorsal spondylodiscitis with a voluminous Pott's abscess compressing the mediastinal structures with a risk of perforating into the trachea.
