  • Cysticercosis of eye
  • Cysticercosis, cerebral
  • Myositis due to cysticercosis
  • Neurocysticercosis
Clinical Information
  • A parasitic infection caused by the larval form of taenia solium. It is a disseminated infection affecting the central nervous system, subcutaneous tissues, lungs, heart and liver. The most serious complications result from infection of the brain parenchyma. Patients may develop seizures, hydrocephalus, encephalopathy and meningoencephalitis.
  • Infection with cysticercus, the larval form of the various tapeworms of the genus taenia (usually t. Solium in man). In humans they penetrate the intestinal wall and invade subcutaneous tissue, brain, eye, muscle, heart, liver, lung, and peritoneum. Brain involvement results in neurocysticercosis.
Applies To
  • Cysticerciasis
  • Infection by Cysticercus cellulosae [larval form of Taenia solium]
