Intestinal vasculitis and pulmonary alveolar hemorrhage in a 41-year-old male with ANCA-positive granulomatosis with polyangiitis (GPA) presenting with abdominal pain and hemoptysis. Axial thoracic CT images (A, B) at two different levels show diffuse mosaic attenuation secondary to geographic areas of ground-glass opacity, suggestive for alveolar hemorrhage. Follow-up CT images (C, D) three days after corticosteroid therapy demonstrate a notable response to treatment. CTE was also done with suboptimal small bowel distention (E, F) at admission to assess the cause of abdominal pain that revealed circumferential mural thickening at ascending colon and distal ileum (thin white arrows) associated with adjacent mesenteric fat haziness. Follow-up CT images (G, H) show complete response to corticosteroid therapy with normal bowel wall thickness (thick white arrows) and a decrease in attenuation of the ileocolic mesenteric root
