Radiologic findings in cases of attempted suicide and other self-injurious behavior

Suicide is one of the leading causes of death in multiple age groups. Therefore, it is important that radiologists be aware of this commonly encountered entity. Attempted suicide may take a variety of forms; those discussed by the authors include sharp force injury, immolation and inhalation, ingestion, hanging, firearm use, jumping from a height, and drowning. Certain radiologic findings are commonly seen in cases of attempted suicide and other self-injurious behaviors. In some cases, especially when the patient is unconscious or is unwilling to provide a history, it may not be apparent that suicide has been attempted until characteristic imaging findings are recognized. Correct identification of suicide attempts on the basis of such findings will ensure that these patients receive appropriate psychiatric treatment. When a suicide attempt is unsuccessful, it is important to be familiar with the complications that may contribute to delayed mortality and morbidity. The radiologist plays an integral role in the acute medical or surgical management of patients who have attempted suicide. In addition, imaging examinations may provide useful forensic information.
