title: [Spontaneous mediastinal and retroperitoneal hematoma caused by trauma in an patient receiving anticoagulation treatment].
abstract: An 80-year-old man had chest and abdominal pains after he fell and twisted his body. He was taking anticoagulant drugs as a precautionary measure to prevent stroke. His chest CT and MRI was taking the presence of a sandglass-like nonenhanced shadow extending from the retromediastinum to the retroperitneum. No mediastinal tumor was detected by gastroscopy or on a chest CT 6 months later. Although the patient gradually became anemic, his vital signs remained normal throughout his hospital stay. The shadow decreased following conservative treatment by transthoracic drainage. We suspect that this tumor was a spontaneous hematoma caused by trauma in a patient receiving anticoagulation treatment.
