Vasculitis of splanchnic arteries in a 43-year-old male with a history of pathologically proven polyarteritis nodosa and segmental jejunal resection due to ischemia. He complains of postprandial abdominal pain, nausea, vomiting, hypertension, and elevated inflammatory markers. CTE was done. Axial and sagittal images (A–C) in the arterial phase demonstrate severe stenosis at the origin of the celiac trunk (thin white arrows) and complete occlusion and irregularity of proximal SMA (thin black arrows). Coronal CT images (D–F) reveal vessel irregularity and mild degree of aneurysmal dilations in a collateral branch between celiac trunk and SMA (white arrowheads), thickening and irregularity in jejunal branches of SMA (black dotted oval) adjacent to the previous site of jejunal resection and anastomosis (white curved arrows). The ileocolic branch of SMA also shows focal aneurysmal dilatation and mild thickening (white dotted oval)
