title: Malignant paragangliomas of the retroperitoneum: value of computed tomography and angiography.
abstract: Four patients with malignant paragangliomas of the retroperitoneum were examined by computed tomography. Angiography was performed in two patients. Computed tomography guided the surgeon in obtaining a biopsy and in considering the possibility of resection. Angiography demonstrated the vascular supply and vascularity of the tumours. Pathological correlation was made.
