[Takayasu's disease associated with Crohn's disease: two identical diseases at different sites?].

The literature reports more than 40 cases of Takayasu disease associated with a Crohn disease. On the occasion of a case hospitalized in our service, we made a review of the literature describing this association and we tried to understand the pathogenesis who could underlie such an association. If both affections have a similar granulomatous vasculitis but arising in different sites, we shall see that the pathological mechanisms at the origin of the disease are complexes and multiples.
