title: [Non-functional renal paraganglioma associated with carotid paraganglioma and appendicular mucocele].
abstract: OBJECTIVE
  A case of nonfunctional renal paraganglioma associated with appendicular mucocele and metachronic carotid paraganglioma is presented.
  
  
  RESULTS
  A 68-year-old patient consulted for abdominal pain. Patient evaluation with US, CT and opague enema showed an elongated mass that compromised the cecum and a solid mass in the right kidney. The patient underwent appendectomy and radical right nephrectomy. The anatomopathological findings showed an appendicular mucocele and renal paraganglioma. The postoperative hormone analyses were normal. A carotid paraganglioma was removed 8 months later.
  
  
  CONCLUSIONS
  Renal tumors arising from neural crest cells are uncommon. To our knowledge, this is the third case of nonfunctional renal paraganglioma reported in the literature. The associated appendicular mucocele was an incidental finding.
