Question: A 43 year old male is diagnosed with a giant cell tenosynovial tumor of the mandibular condyle.  Surgical treatment is undertaken that involves a modified infratemporal fossa approach.  After removing the zygomatic arch and reflecting the temporalis muscle inferiorly, dissection is carried medially along the skull base.  Brisk arterial bleeding is encountered from a small vessel entering the skull base just lateral to foramen ovale.  What vessel was likely injured?
