In this case the iliopsoas hemorrhage was due to warfarin leading to supratherapeutic INR.

Symptoms of pain, inability to weight bear and sensory deficits can be explained by the mass effect exerted by the hematoma.

In cases of large iliopsoas hematomas femoral nerve may be compressed producing femoral nerve neuropathy.

Fortunately for the patient he remained haemodynamically stable and the findings on CTA were consistent with only small ongoing bleed which was safely managed with reversal of anticoagulation and did not require intervention.
