Pseudo-aneurysm are due to arterial wall disruption leading to the formation of a perfused sac that communicates with the arterial lumen. This entity remains at highly significant risk of rupture. The majority of cases are presenting as haemothorax.Intercostal artery pseudo-aneurysms are extremely rare, most of them were associated with surgical interventions or blunt thoracic trauma, only one case was reported after a knife stabbing wound.We describe the case of a young male patient who was stabbed with a knife in his posterior left chest side and was first operated to evacuate a contained hematoma only to re-consult after 20 days for a pulsatile mass which proved to be an intercostal artery pseudo-aneurysm. The patient was successfully surgically managed and was discharged 4 days after the surgery.

Takayasu arteritis is a chronic inflammatory disease of the aorta, its main branches, and the pulmonary arteries. It is characterized by arterial stenoses and ischemic manifestations.Aneurismal dilatation of the ascending thoracic aorta associated with aortic regurgitation is rare in Takayasu disease.We report the cases of a 43-year-old woman with a Takayasu disease since 18 years, who presented a dyspnea and chest pain. Computed tmography and trans-thoracic echocardiography confirmed an ascending aortic aneurysm associated to a severe aortic insufficiency.The patient will underwent surgical replacement of the ascending aorta and the aortic valve.
