[Angiography of primary retroperitoneal tumor--case report and proposal of a flow chart]

The development of ultrasonography and CT scanning has facilitated the diagnosis of primary retroperitoneal tumors. However, the tumor resection rate remains low. Factors such as tumor histology and stage of the disease play a role. Angiographic study of the tumor vessels is important in determining the procedures to the used in operative treatment. We present 3 primary retroperitoneal tumors and one malignant adrenal tumor discuss the importance of angiographic evaluation in the resection of recurrent tumors. A flow chart for surgically treated primary retroperitoneal tumor is proposed.
