Warfarin-induced iliopsoas hemorrhage with subsequent femoral nerve palsy.
We present the case of a 28-year-old man on chronic warfarin therapy who sustained a minor muscle tear and developed increasing pain and a flexure contracture of the right hip. Surgical exploration revealed an iliopsoas hematoma and femoral nerve entrapment, resulting in a femoral nerve palsy and partial loss of quadriceps functions. Anticoagulant-induced femoral nerve palsy represents the most common form of warfarin-induced peripheral neuropathy; it is characterized by severe pain in the inguinal region, varying degrees of motor and sensory impairment, and flexure contracture of the involved extremity.
