title: Secondary infection of intracranial hydatid cyst with Clostridium ramosum.
abstract: BACKGROUND
  Brain involvement in hydatid disease occurs in 1-2% of all Echinococcus granulosus infections. Secondary infection of intracranial hydatid cysts is extremely rare.
  
  
  METHODS
  In this case report, we present a secondary infection of an intracranial hydatid cyst due to Clostridium ramosum, which is an extremely rare infectious pathogen in neurosurgical practice, and a potential pitfall in neuroradiological investigations.
