Percutaneous vertebroplasty can cause asymptomatic azygos-vein cement embolism presenting as the cement bridge sign.
This case report describes the 'cement bridge sign,' representing a complete azygos-vein pathway of asymptomatic bone cement embolism incidentally detected during the workup for an acute inferoposterior myocardial infarction.

History of vertebroplasty warrants considering cement embolism in unexplained MI; leaves open true incidence and screening needs.
An elderly woman who had undergone percutaneous vertebroplasty with bone cement in middle age presented with sudden chest pain. Electrocardiography indicated acute inferoposterior myocardial infarc...
