KEY FACTS

  • Top Differential Diagnoses

    • Diagnostic Checklist

      TERMINOLOGY

      • Definitions

        • Primary retroperitoneal tumors arising from ganglion cells, parasympathetic system, or nerve sheaths
      • Overview

        • Neurogenic tumors: ~ 10% of primary retroperitoneal tumors
        • Neurogenic tumors can arise from
          • Ganglionic cells
          • Paraganglionic cells
          • Nerve sheath
        • Neurogenic tumors affect younger population and have better prognosis compared to retroperitoneal mesenchymal tumors
