Summary
A rare case of ulnar neuropathy occurred in an elderly woman due to arm hemorrhage after anticoagulant therapy for a transient ischemic attack. This highlights a potential complication of anticoagulation.
Area of Science:
- Neurology
- Vascular Surgery
Background:
- Ulnar nerve injuries can occur at multiple sites.
- Aortic stenosis and hypertension are significant comorbidities.
- Anticoagulation is a common treatment for transient ischemic attacks.
Observation:
- An elderly woman with comorbidities presented with stroke-like symptoms.
- She was treated with anticoagulants for a transient ischemic attack.
- Post-treatment, she developed a diffuse intramuscular hemorrhage in her arm.
Findings:
- The hemorrhage compromised ulnar nerve fibers.
- Clinical, radiologic, and electrodiagnostic findings confirmed ulnar neuropathy.
- This is the first reported instance of ulnar neuropathy secondary to arm hemorrhage.
Implications:
- Anticoagulation therapy may carry risks of spontaneous hemorrhage, even in the arm.
- This case expands the differential diagnosis for ulnar neuropathy.
- Awareness of this complication is crucial for clinicians managing patients on anticoagulants.
