Une opacité médiastinale inhabituelle

A 36-year-old immunocompetent male from Senegal with an uneventful history was admitted for exploration of a hydroaeric collection in the posterior mediastinum. Multifocal tuberculosis was diagnosed. Computed tomography-guided drainage removed 600 cc of caseum. The diagnosis as rupture of an intrathoracic Pott's abscess complicated by a probably esophageal fistula. The clinical course was rapidly favorable with later development of mediastinal fibrosis. This uncommon case illustrates the contribution of interventional radiology recently developed in the Principal Hospital in Dakar, Senegal.
