Preoperative embolization as an adjunct to the operative management of mediastinal Castleman disease.

Castleman disease usually presents in children as a localized mass with prominent feeding vessels. The mainstay of treatment of Castleman disease is surgical resection; historically, resection is associated with excessive blood loss. These tumors are well known to have large feeding vessels and, thus, are amenable to preoperative arteriography with embolization. The authors present a case of Castleman disease treated with preoperative embolization as an adjunct to operative management.
