title: Orbital paraganglioma: report of a rare case.
abstract: METHODS
  Paragangliomas of the orbit are extremely rare tumors. We report a well-documented case of orbital paraganglioma in a 45-year-old man who presented with proptosis and decreased vision. The patient underwent complete excision of the tumor with preservation of orbital structures. There was total regression of symptoms after surgery and vision was well maintained.
