title: [Iliopsoas muscle hematoma during treatment with warfarin].
abstract: Warfarin is a widely used drug for the prevention of thromboembolic events. Knowledge of its adverse effects is necessary for patient follow-up. Although the development of blood dyscrasias is a potential complication in these patients, retroperitoneal bleeding is rare. This article reports the case of a patient who developed iliopsoas muscle hematoma during treatment with warfarin after implantation of a metallic prosthetic aortic valve. The clinical manifestations involved important differential diagnoses.
