Psoas haematoma and femoral neuropathy associated with enoxaparin therapy

Haemorrhage into the iliopsoas muscle causing femoral neuropathy is an infrequent complication of haemophilia or anticoagulant therapy. The association of an iliopsoas haematoma with enoxaparin therapy is very rare. We describe a case of femoral neuropathy secondary to psoas haematoma in a patient who was on enoxaparin therapy for suspected non-Q wave myocardial infarction. There is no clear consensus for the treatment of these haematomas, with both surgical and conservative options advocated. In this case, our patient recovered fully following conservative management.
