Case 130. Cysticercosis of brain (neurocysticercosis) (44 y-o F)
         
    Biopsy from multinodular brain lesions, manifesting convulsion and consciousness disturbance

In the brain, cyst wall cells of cysticercus proliferate like a bunch of grapes to present characteristic serrated appearance (HE, low power). This state is called as racemous cysticercosis.   The cyst wall of cysticercus is composed of eosinophilic outer cuticles, single-layered subcuticular cells and thin, myxoid cytoplasm with tubular structures (HE, high power). No protoscolex can be discerned.
     
 
     
Autopsy findings of neurocysticercosis in the same case
Marked inflammatory reaction against the cyst wall of cysticercus (HE, low power).. The destroyed cyst wall components are mainly distributed in the subarachnoid space, and provoke marked inflammatory reaction.
  Autopsy findings of neurocysticercosis in the same case
Foreign body reaction against the cyst wall of cysticercus (HE, high power).. Usually, the viable cysticerca do not provoke inflammatory reaction. When they are dead by treatment, foreign body reactions are induced.
     
   
     
Reference case 130A
CT scans, demonstrating multiple nodular lesions in the cerebral cortex in a 21 y-o Japanese female, who complained of muscle weakness in the right arm (left: plain, right: enhanced). The patient ate Kimuchi imported from the southern part of Korea, possibly contaminated with fertilized eggs of Taenia solium. Cysticercus cellulosa is usually seen in the meat of pig, an intermediate host animal. The final host of this tapeworm T. solium is human.
