Benign tumor: Hemangioma is the most common benign tumor of the liver. Small hemangiomas(like yours) cause no symptoms, and no treatment is necessary. Once the diagnosis is confirmed(e.g. with contrast enhanced MRI) it is debatable whether any follow up at all is necessary. Some physicians may recommend follow up at 6 or 12 months, ultrasound would be the simplest way to do this.
