title: Concurrent intermediate uveitis and an enhancing intracranial lesion as the initial manifestation of sarcoidosis.
abstract: BACKGROUND
  Posterior segment involvement has been described to be associated with central nervous system involvement in sarcoidosis as a result of direct sarcoid tissue infiltration or mass effect of a cerebral lesion. However, isolated intermediate uveitis occurring concurrently with central nervous system involvement prior to extensive systemic disease is rare.
  
  
  METHODS
  We describe a patient with neuro-ophthalmic manifestations of intermediate uveitis and an enhancing basal ganglia lesion at initial presentation, in the absence of extensive systemic disease.
  
  
  METHODS
  He was treated with high-dose systemic steroids which was progressively tailed down over 6 months.
  
  
  RESULTS
  There was prompt resolution of vitritis with good preservation of visual acuity.
  
  
  CONCLUSIONS
  The difficulties of the initial diagnosis of sarcoidosis and the indications for initiation of steroid therapy are illustrated. We use this case to emphasise the need for a high clinical suspicion of sarcoidosis in the presence of similar unusual and seemingly unrelated combinations of neurological manifestations so as to facilitate the prompt institution of appropriate treatment when indicated.
