What Is Cysticercosis?
Introduction:
Cysticercosis
- Introduction:
- Swine cysticercosis is an infectious disease caused by the infection of larvae of hookworms in pork through fecal mouth infection.
- This is the most common parasitic infection involving the central nervous system. Seizures can occur in 90% of patients in developing countries. The parenchymal phase is the most common type of cysticercosis. The most common site of the lesion is at the junction of gray and white matter in the brain. The parasites come through different stages, and each stage has different CT and MR image characteristics.

Medical image classification of cysticercosis :
- 1. Cystic stage: CT shows low-density unreinforced placeholders. MR is a cystic cerebrospinal fluid signal; T2 can show the morphology of high-signal cysticercosis, without edema and usually not enhanced.
- 2. Gelatinous phase: CT shows equal or low-density mass, with peripheral enhancement and edema. MR is stronger than the cerebrospinal fluid signal; there is edema around, and the cyst wall is strengthened.
- 3. Granular stage: CT shows nodular high-density space. The MR upper capsule wall thickened and contracted, and decreased in water with nodular or annular reinforcement.
- 4. Calcification stage: Parasites die, and nodular thin-walled tissue calcification can be seen, which is easier to show on CT.
