title: Solitary idiopathic choroiditis.
abstract: BACKGROUND
  There are multiple conditions associated with the formation of a solitary choroidal granuloma. However, in many cases, solitary choroiditis remains idiopathic in spite of an extensive systemic evaluation.
  
  
  METHODS
  A 26-year-old man presented with an asymptomatic pale choroidal lesion that had the features of solitary idiopathic choroiditis.
  
  
  RESULTS
  Optical coherence tomography and fundus autofluorescence were performed and showed lesion features.
  
  
  CONCLUSIONS
  Solitary idiopathic choroiditis is a rare condition of unknown aetiology that sometimes can be mistaken as an intraocular tumour. The use of emerging multimodal imaging is of great importance in the diagnosis of this condition.
