Solitary Idiopathic Choroiditis

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.
