title: Glial heterotopia of the orbit: a rare cause of proptosis.
abstract: BACKGROUND
  Glial heterotopia is defined as presence of normal glial tissue in an unusual location without connection with the brain. It is a very rare clinical entity occuring mostly in the head and neck region which is generally present at birth. Orbital location is very rare.
  
  
  METHODS
  We report a case of a 4-month-old girl presenting congenital proptosis with progressive increase. CT scan revealed an intraorbital mass without bony defect. The patient was operated, and resection was subtotal. Histologically, the tumor was composed of glial tissue with plexus choroid and pathologist concluded glial heterotopia. The child is under constant medical supervision because recurrences can be observed after incomplete resection; she had no new clinical signs at 18 months follow-up.
