title: [Splenosis: underdiagnosed entity].
abstract: OBJECTIVE
  To report a case of renal splenosis in a patient that had previously undergone splenectomy due to traumatic rupture.
  
  
  RESULTS
  A 42-year-old patient consulted for pancreatitis. A CT scan disclosed a mass behind the tail of pancreas, MRI assessment with gadolinium enhancement showed a left renal mass which was surgically resected. Histopathological analysis of the surgical specimen demonstrated splenic tissue.
  
  
  CONCLUSIONS
  Splenosis should be considered in splenectomized patients with lesions compatible with tumors and should be distinguished from hyperplasia of accessory spleens.
