title: Asymptomatic lumbar vertebral erosion from inferior vena cava filter perforation.
abstract: In 2002, a 24-year-old female trauma patient underwent prophylactic inferior vena cava filter placement. Recurrent bouts of renal stones prompted serial CT imaging in 2004. In this brief report, we describe erosion and ossification of the L3 vertebral body by a Greenfield filter strut.
