There are various causes of facial canal enlargement. From congenital anomalies to neoplasms, many pathologic conditions should be considered. However, normal variants of vascular anatomy can also result in facial canal enlargement on temporal bone imaging. In order to avoid unnecessary procedures and complications, such as bleeding and facial nerve injury, this possibility should also be taken into account. A case of a 50-year-old male who was diagnosed with facial canal enlargement because of venous engorgement in the facial canal is herein described.
