title: Cerebral toxoplasmosis: unusual MRI findings.
abstract: BACKGROUND
  Single cerebral toxoplasmic lesions are rarely explored.
  
  
  METHODS
  Through magnetic resonance imaging, 10 lesions were analyzed regarding location, signal intensity, contrast enhancement, eccentric target, and meningeal uptake.
  
  
  RESULTS
  Five lesions were corticosubcortical and in the deep three (60%) had infratentorial locations. Iso- or hypointense signal predominated in T1 sequence, but in T2, there was variability. Perilesional edema and ring contrast enhancement occurred in 100% of lesions, but eccentric targets and meningeal uptake were less frequent.
  
  
  CONCLUSIONS
  Even in the presence of single lesions, iso- or hypointense signal in T1, perilesional edema, and ring enhancement are suggestive of cerebral toxoplasmosis.
