title: [Orbital lymphangioma: case report].
abstract: A case of orbital lymphangioma in a 9 year-old female, with proptosis (Hertel= 29 mm), ocular motility restriction, pain and visual loss due to compressive optic neuropathy is described. A magnetic resonance imaging (MRI) exam showed an expansive cystic lesion in the extraconal space of the right orbit, non-infiltrating with intralesional hemorrhage. The patient had no improvement with steroid treatment. A transconjunctival puncture with 35 ml aspiration of a "chocolate color" fluid (which was confirmed by cytologic study as a hemorrhagic fluid) was performed. Exacerbations occurred after an intralesional hemorrhage (pain and increase of proptosis). The lesion was excised via lateral cutaneous approach (a lateral canthotomy and removal of the right orbital wall was performed done for decompression) and lower transconjunctival approach.
  
  
  CONCLUSIONS
  Lynphangioma is a challenging disease and difficult to treat, with potential visual and cosmetic complications and the possibility of frequent recurrences.
