FINDINGS: The visualized proximal duodenum displays circumferential mural thickening, single wall thickness 7 mm. Outer wall to outer wall diameter is 29 mm.
Transferred to pediatric rheumatology service. Diagnosis of IgA vasculitis was confirmed based on clinical features, abdominal US, and skin biopsy findings. Treated with steroids.
Case Discussion
IgA vasculitis (Henoch-Schonlein purpura) gives rise to gastrointestinal symptoms in one half of affected children, due to submucosal hemorrhage and edema. Most common sites are duodenum, stomach and colon. Intussusception is the commonest GI complication.
