title: Vertebral Body Erosion and Subsequent Back Pain Secondary to a Vena Cava Filter.
abstract: BACKGROUND
  A patient with multiple open lumbar procedures, the most recent of which was complicated by symptomatic pulmonary embolus, underwent placement of an inferior vena cava filter (IVCF). Two years after placement, she developed low back pain with radicular symptoms. CT of the lumbar spine demonstrated vertebral body erosion from the IVCF strut. In this brief report, we describe L2 vertebral body erosion, radiographic findings, and a brief review of the literature.
  
  
  OBJECTIVE
  To describe radiographic findings of vertebral body erosion from IVCF as well as review the literature regarding this and other complications of IVCF placement.
  
  
  METHODS
  Retrospective, single patient chart review.
  
  
  RESULTS
  The patient's IVCF was successfully removed without complication. The pain and radicular symptoms resolved by one month follow-up.
  
  
  CONCLUSIONS
  Based on the literature, most IVCFs with evidence of bony erosion are removed except when patient comorbidities, goals of care, or a complete absence of symptoms make removal inadvisable.
