[Aneurysm of the celiac trunk. A review of the literature. Apropos of a new case].

Aneurysms of celiac trunk are rare (82 cases reported worldwide), and the clinical picture is usually little suggestive of the lesion, which may be totally asymptomatic. Positive diagnosis and determination of possible extension of the disease, as well as postoperative follow up is ensured by modern imaging techniques (ultrasound, CT scan, digital subtraction angiography). Etiology of the aneurysm varies but is generally atheromatous disease or intimal fibrodysplasia.
