title: Retroperitoneal inflammatory myofibroblastic tumor.
abstract: BACKGROUND
  Inflammatory myofibroblastic tumor (IMT) is a neoplasm of unknown etiology occurring at various sites. By definition, it is composed of spindle cells (myofibroblasts) with variable inflammatory component, hence the name is IMT.
  
  
  METHODS
  The present case is of a 46 years old woman presented with a history of flank pain, abdominal mass and intermittent hematuria for last 6 months. The initial diagnosis was kept as renal cell carcinoma. Finally, it turned out to be a case of retroperitoneal IMT. The patient was managed by complete surgical resection of the tumor.
  
  
  CONCLUSIONS
  IMT is a rare neoplasm of uncertain biological potential. Complete surgical resection remains the mainstay of the treatment.
