title: Imaging of childhood inflammatory myofibroblastic tumor.
abstract: BACKGROUND
  Inflammatory myofibroblastic tumor is a rare benign neoplasm and most commonly involves the lung but occurs in extrapulmonary locations.
  
  
  OBJECTIVE
  To present imaging findings in inflammatory myofibroblastic tumors in children based on a single-centre experience.
  
  
  METHODS
  We retrospectively reviewed CT and MRI findings of children diagnosed with inflammatory myofibroblastic tumor in a single institution.
  
  
  RESULTS
  We identified 15 children (range: 1-17 years) with inflammatory myofibroblastic tumor. The tumor was localized to the lung (n = 5), mediastinum (n = 3), trachea (n = 1), bronchus (n = 1), abdomen (n = 2) and orbit (n = 3). All the extraorbital tumors were solid masses with homogeneous or heterogeneous enhancement. Four lung tumors and one posterior mediastinal tumor contained calcification. Local recurrence following surgical removal occurred in two children with invasion of the esophagus and of the left atrium in one. Localized masses were seen in all children with orbital tumour. Two of these had episcleritis and perineuritis; one had episcleritis, tendonitis, perineuritis, myositis and dacryoadenitis.
  
  
  CONCLUSIONS
  The locations and imaging features of inflammatory myofibroblastic tumors are variable.
