Hemorrage into or around nerves

1. Patients on anticoagulation or with bleeding disorders develop hematomas that compress nerves.

2. Hemorrhage into nerves occurs particularly in patients with bleeding disorders, including leukemia, hemophilia and thrombocytopenia

3. Acute stretch injuries may rupture an intraneural blood vessel and cause bleeding into a nerve. For example, the common peroneal nerve in popliteal fossa may be affected after a severe inversion injury of the ankle.
