Aggressive preoperative management and extended surgery for inflammatory pseudotumor involving the hepatic hilum in a child.

Inflammatory pseudotumors involving the hepatic hilum are rare. Only 14 cases have been reported (Table). Liver transplantation has been required when the pseudotumor has invaded extensively into the right and left lobes. (1,2) However, transplantation is associated with the lifelong use of immunosuppressants. This is particularly problematic in children. we report a case of a 6-year-old boy with an inflammatory pseudotumor extensively invading the hepatic hilum who was treated with aggressive surgical excision using the techniques devised for the treatment of hilar cholangiocarcinoma.
