title: Orbital schwannoma: histopathologic correlation with magnetic resonance imaging.
abstract: METHODS
  A 45-year-old man presented with an orbital tumour that on MRI was most consistent with a hemangioma. Histopathologic examination disclosed an orbital schwannoma, with cystic and mucinous degeneration complicating radiologic interpretation.
  
  
  CONCLUSIONS
  An array of ancillary studies including orbital ultrasonography may be useful in substantiating the diagnosis preoperatively.
