A 72-year-old patient was referred for one-year intermittent abdominal pain. Abdominal ultrasound showed a 7.3 × 7.7 cm retroperitoneal mass, which partially compressed the inferior cava vein. Radiological imaging demonstrated a retropancreatic lesion, heterogeneous, with well-defined edges, without clear dependence of any adjacent structure. Cytological diagnosis of ganglioneuroma was made by EUS-FNA. The immunohistochemistry in the resection specimen revealed confirmed the previous finding. Ganglioneuromas are rare benign tumors, diagnosis is based on pathology and complete surgical resection is the treatment of choice.

EUS-FNA is a useful method in the investigation of retroperitoneal masses, for an early, rapid, minimally invasive diagnosis.
