Background/rationale: Tuberculosis is a public health issue. Extra-pulmonary presentations are rare and sometimes hard to diagnose and manage.

[Delayed tamponade: Four cases of rare complication of blunt chest trauma].

Delayed post-traumatic pericardial effusion is a rare condition after blunt trauma. The diagnosis of the effusion can be made by the clinical signs, which is not very specific and the cardiac echography. The etiological diagnosis remains difficult because it requires the elimination of the other causes of pericarditis.

[Management of traumatic and iatrogenic arterial pseudoaneurysms in a tropical environment].

A false aneurysm or pseudoaneurysm (PA) is the formation of a pulsatile and encapsulated hematoma in communication with the lumen of a perforated artery. Its origin is different but most cases are associated with a traumatic event. Currently, the referenced treatment is endovascular surgery but it is not feasible for the majority of vascular surgeons working in a tropical environment.
