title: Acquired Toxoplasmosis Presenting with a Brainstem Granuloma in an Immunocompetent Adolescent.
abstract: BACKGROUND
  Toxoplasmosis is an uncommon disease in immunocompetent people.
  
  
  METHODS
  We report an adolescent boy with central nervous system toxoplasmosis who presented with progressive lower cranial nerve palsies and a ring-enhancing lesion on neuroimaging.
  
  
  METHODS
  Diagnosis of toxoplasmosis was confirmed on histopathology of the excised lesion.
  
  
  CONCLUSIONS
  Toxoplasmosis should be considered in the differential diagnosis of focal brain lesions irrespective of immune status.
