Neurocysticercosis

Discussion:

Multiple bilateral supra- and infra-tentorial predominantly extra-axial as well as intra-axial ring enhancing and calcified lesions , consistent with neurocysticercosis (granular / calcified phase) with mild supra- and infra-tentorial hydrocephalic changes.     

The main differential diagnosis is tuberculosis; however it is :

  • parenchymal marginally enhancing cystic lesions with tuberculous basal meningitis. The tuberculoma may show restricted diffusion with T2 hypointense wall.
  • extra-cerebral pulmonary lesions is common association.
