Superior mesenteric artery syndrome in a 13-year-old girl with henoch schonlein purpura: A case report

Abstract

Superior Mesenteric Artery (SMA) syndrome is an uncommon gastrointestinal blockage caused by the compression of the third section of the duodenum between the abdominal aorta and the superior mesenteric artery. Henoch Schönlein Purpura (HSP), or IgA vasculitis, is the most common childhood vasculitis, marked by palpable purpura, arthralgia, gastrointestinal symptoms and renal involvement. The coexistence of both conditions is exceptionally rare. We report a 13-year-old girl who presented with persistent epigastric pain and bilious vomiting, followed by cutaneous purpura and mild hematuria. Imaging and histopathology confirmed SMA syndrome and HSP respectively. Management with nutritional support and corticosteroids led to complete resolution. This case underscores the importance of recognizing dual pathologies and the role of steroids in treating SMA syndrome secondary to HSP.
