title: Echography as a useful adjunct in the diagnosis of orbital solitary fibrous tumor.
abstract: OBJECTIVE
  To describe the echographic features of solitary fibrous tumor of the orbit.
  
  
  METHODS
  A retrospective review of 3 patients with solitary fibrous tumor of the orbit and a literature review were performed.
  
  
  RESULTS
  Three patients with orbital solitary fibrous tumor were studied with standardized echography and 3 other cases of orbital solitary fibrous tumor with ultrasound descriptions were identified in a literature review. Consistent echographic features of the 6 orbital solitary fibrous tumors included firmness, low to medium internal reflectivity, regular internal structure, moderate sound attenuation, and some degree of vascularity.
  
  
  CONCLUSIONS
  Standardized echography is a useful adjunct in the evaluation of orbital solitary fibrous tumors and can help differentiate these tumors from other orbital lesions.
