Femoral nerve palsy associated with bilateral spontaneous iliopsoas haematomas: a complication of venous thromboembolism therapy.

We report a case of femoral nerve palsy occurring as a result of spontaneous bilateral iliopsoas haematomas in an elderly patient on treatment dose dalteparin for a suspected pulmonary embolus. There are limited case reports in the literature relating to this rare problem, and their management is controversial. We advocate non-operative treatment in the instance of a delayed presentation in a frail elderly patient with a subsequent good functional outcome.
