[Inflammatory pseudotumor of the intestine caused by necrotizing vasculitis in the course of Horton disease]. / Pseudo-tumeur inflammatoire de l'intestin par vascularite nécrosante au cours d'une maladie de Horton.

The authors report a case of giant-cell arteritis involving the digestive tract, revealed by a subocclusive syndrome. It appeared to be an unusual pattern according to the location, the tumour aspect and the histologic appearance of a periarteritis nodosa type. The digestive involvement and the histologic appearance are discussed in a review of the literature, as well as the link with the periarteritis nodosa.
