title: Magnetic resonance imaging visualization of hemorrhage into a suprapatellar pouch in a child with hemophilia.
abstract: OBJECTIVE
  Magnetic resonance imaging (MRI) was used for evaluation of refractory joint swelling in a 7-year-old boy with hemophilia.
  
  
  METHODS
  This patient with no evidence of an inhibitory had refractory left knee swelling despite receiving appropriate factor VIII concentrate infusions.
  
  
  RESULTS
  A plain radiograph showed soft tissue swelling and a calcification in the left suprapatellar region. On MRI a discrete suprapatellar pouch could be detected and was subsequently surgically resected.
  
  
  CONCLUSIONS
  We believe that MRI should be considered when evaluating children with hemophilia who have refractory joint swelling and no evidence of an inhibitor.
