Spontaneous coeliac artery dissection.

A patient with spontaneous coeliac artery dissection that presented as upper abdominal pain is reported. This was diagnosed on contrast-enhanced multislice helical CT. The patient was treated conservatively and follow-up CT showed mild aneurysmal change of the splenic artery and a small splenic infarct. Isolated dissection of the visceral arteries (and, in particular, the coeliac artery) is extremely rare. With such limited evidence, decisions over best management are difficult, but depend on initial severity and progression at follow up.
