title: Report of diffusion-weighted MRI in two cases with different cerebral hydatid disease.
abstract: OBJECTIVE
  To present MRI findings in two cases of cerebral hydatid disease with an emphasis on diffusion-weighted imaging (DWI) findings of Echinococcus granulosus (EG) versus Echinococcus alveolaris (EA).
  
  
  RESULTS
  EG lesions were isointense with cerebrospinal fluid in all sequences including DWI. On DWI, EA lesions remained hypointense on b = 1000 s/mm2 diffusion-weighted images. Apparent diffusion coefficient (ADC) values of EG and EA lesions were completely different from each other, 2.88 +/- 0.24 x 10(-3) s/mm2 and 1.33 +/- 0.15 x 10(-3) s/mm2, respectively.
  
  
  CONCLUSIONS
  The ADC values could not be used to discriminate from other differential diagnoses.
