Large Recurrent Mediastinal Abscess Presenting With Cardiopulmonary Collapse.

Mediastinal abscesses are rarely encountered but pose a potential threat for cardiopulmonary collapse given the close proximity of vital structures. Our focus is to illustrate a case of a mediastinal abscess that was promptly diagnosed and treated, leading to complete resolution of the airway and circulatory compromise. The proposed pathogeneses behind mediastinal abscesses are discussed at length.
