Abstract
Bilateral iliopsoas hematoma is an uncommon phenomenon, which has been described in
individuals receiving anticoagulation therapy. The hematoma is caused by bleeding
of arteries to the muscle. In rare cases, pseudoaneurysms can also be formed. We present
a case of an adolescent, with partial factor XI deficiency, who experienced a mild
fall. Imaging studies revealed large bilateral iliopsoas hematomas and bilateral iliopsoas
pseudoaneurysms. One pseudoaneurysm was demonstrated by angiography and was embolized
with micro coils. The second, more persistent one, was sealed via ultrasound-guided
thrombin injection, with excellent morphological and clinical results.
