leukozytoklastische Vaskulitis

Imaging of

intestinal vasculitis focusing on MR and CT enterography: a two-way street between radiologic findings and clinical data. Intestinal vasculitis in a 28-year-old male with leukocytoclastic vasculitis presenting with abdominal pain, chest discomfort, and erythematous rashes with palpable purpura on the lower extremities. An abdominopelvic CT scan with IV and oral contrast was obtained. Axial images (A, B) show mild bilateral pleural effusion and pelvic free fluid. Also, axial CT (C) demonstrates mild concentric mural thickening of the distal ileal loop (thin black arrows). The patient underwent a biopsy of skin lesions. The histopathologic study revealed leukocytoclastic vasculitis. Corticosteroid therapy started. Then, MRE was done after five days. Axial post-contrast T1-W images (D, E) display mild mural thickening and hyperenhancement (thick white arrows) in the distal ileal segments. Mild engorgement of adjacent mesenteric vessels (white dotted oval) is also evident, and there is no ascites. Imaging findings and clinical data were indicative of an excellent response to therapy
