Preoperative embolization of a retroperitoneal malignant nervous sheath tumor

Malignant peripheral nerve sheath tumors are rare tumors compromising about 5% of all malignant soft tissue tumors. Treatment of these tumors is surgical but surgical resection is not always easy. We are presenting a low grade retroperitoneal malignant peripheral nerve sheath tumor in which we used selective arterial embolization before surgery and surgical resection became possible.
