title: A case of bilateral hemarthrosis due to pseudoaneurysms in a patient on anticoagulation therapy.
abstract: Hemarthrosis can occur in patients with a predisposition to hemorrhage, such as hemophiliacs or patients on anticoagulation therapy. If hemarthrosis recurs after supportive treatment, however, other etiologies such as anatomical abnormalities should be considered. Spontaneous articular pseudoaneurysm associated with anticoagulation treatment has not been reported previously. We describe a patient on anticoagulation therapy with bilateral hemarthrosis due to pseudoaneurysms. After failing to respond to the correction of over-anticoagulation, magnetic resonance imaging led to the diagnosis of articular pseudoaneurysm. The patient was treated successfully by transarterial embolization.
