title: PLANTAR THROMBOPHLEBITIS: MAGNETIC RESONANCE IMAGING FINDINGS.
abstract: OBJECTIVE
  Demonstrate the magnetic resonance imaging (MRI) findings in plantar thrombophlebitis.
  
  
  METHODS
  Retrospective review of twenty patients with pain in the plantar region of the foot, in which the MRI findings indicated plantar thrombophlebitis.
  
  
  RESULTS
  A total of fourteen men and six women, mean age 46.7 years were evaluated. Eight of these patients also underwent Doppler ultrasonography, which confirmed the thrombophlebitis. The magnetic resonance images were evaluated in consensus by two radiologists with experience in musculoskeletal radiology (more than 10 years each), showing perivascular edema in all twenty patients (100%) and muscle edema in nineteen of the twenty patients (95%). All twenty patients had intraluminal intermediate signal intensity on T2-weighted (100%) and venous ectasia was present in seventeen of the twenty cases (85%). Collateral veins were visualized in one of the twenty patients (5%). All fourteen cases (100%), in which intravenous contrast was administered, showed perivenular tissues enhancement and intraluminal filling defect. Venous ectasia, loss of compressibility and no flow on Doppler ultrasound were also observed in all eight cases examined by the method.
  
  
  CONCLUSIONS
  MRI is a sensitive in the evaluation of plant thrombophlebitis in patients with plantar foot pain.
