In the new security environment, there is a clear and present danger of terrorists using non-conventional weapons to inflict maximum psychological and economic damage on their targets. This article examines two scenarios of radiation contamination and injury, one accidental in nature leading to environmental contamination, and another of deliberate intent resulting in injury and death. This article also discusses the management of injury from radiological dispersion devices or dirty bombs, with emphasis on the immediate aftermath as well as strategy recommendations.

A case of suspected radiation myelitis based on clinical history, previous irradiation, neurologic deficit in the irradiated volume, and normal myelogram is reported. At autopsy, intramedullary metastatic disease was found, but not radiation damage. All radiation details must be considered before making the diagnosis of radiation myelitis with confidence. It is important not to exclude other potentially helpful treatment, such as surgery or chemotherapy, by the presumptive diagnosis of radiation myelitis.

Two cases demonstrating the computed tomographic (CT) appearance of inferior vena cava (IVC) duplication are presented, and the embryological, clinical, and radiological significance are discussed. Knowledge of caval anomalies can prevent misinterpretation of mediastinal masses, iliac occlusion with venous collaterals, or paravertebral lymph node enlargement. A duplicated IVC can be distinguished from para-aortic lymphadenopathy either by recognition of renal vein drainage or through intravenous contrast enhancement of the venae cavae.
