ABSTRACT

Epidural vein thrombosis is a rare cause of lumbosciatica than can clinically and radiologically mimic other causes of nerve root compression such as disc herniation. We describe 3 unusual cases of spinal epidural plexus vein thrombosis illustrating the difficulty in preoperative diagnosis of this entity. Misinterpretation of imaging findings can lead to an erroneous diagnosis and inappropriate treatment. Knowledge of certain radiologic findings will increase the likelihood of recognizing epidural vein thrombosis.

ABSTRACT

A 59-year-old man with a pacemaker who was admitted for evaluation of fever was found to have a redundant loop of the ventricular lead and a vegetation attached to it. An FDG PET/CT revealed a focus of FDG uptake at the ventricular lead loop. Surgical extraction of the pacemaker device confirmed a Propionibacterium acnes pacemaker endocarditis. We hypothesize that the redundant loop of the ventricular lead induced a chronic mechanical stress both to the tricuspid valve and to the lead itself, facilitating the bacterial colonization of the lead.
