Labs neutrophilic leucocytosis (17000) with normocytic anemia , high inflammatory markers, elevated amylase and lipase and 2-3 RBC /hpf in urine.A provisional diagnosis of IgA vasculitis with GI involvement was made and started on IV Methylprednisolone at 10 mg/kg .She had persistent severe abdominal pain and upper GI scopy showed bile in bile in stomach, NJ tube was placed and secretions monitored. And once secretions reduced, started on oral liquid feeds. Repeat CT abdomen showed edematous bowel loops with pneumatosis and portal venous gas, indicating intestinal perforation. 
Blood cultures grew Klebsiella species. Antibiotics were hiked . A laparotomy was done and 20 cm of small bowel was resected , creating a loop stoma bowel around 40 cm from the DJ and remaining bowel was placed back. She responded well to surgery and was weaned off ventilator and oral intake begun. Steroids were tapered and MMF was added and was discharged after recovery, with stable vitals and advise for regular follow up.
