4. Introduction:
 Neurocysticercosis is the infection of CNS by larval stage of pork
tapeworm Taenia solium.
 Infection commonly targets subarachnoid spaces, spinal cord, eyes and
muscles.
 The most common manifestation of the disease is epilepsy, but can have
several other manifestations.

5. Etiology of the disease:
Neurocycticercosis is a special form of infectious parasitic disease
cysticercosis which is caused by the infection with Taenia solium, a tapeworm
found in pigs.
Source of Infection:
consumption of contaminated pork

6. Epidemiology:
 NCC is endemic in sub-Saharan Africa, Latin America and Asia including
subcontinent India and china.
 It is one of the neglected tropical diseases.
 Disease is rare in developed countries.
 Epidemiology of the disease is also associated with poor sanitation.

7. Life cycle:

8. Pathophysiology of disease:
Neurocysticercosis mostly involves cerebral cortex followed by cerebellum.
The pituitary gland is very rarely involved in Neurocysticercosis. The cysts
may rarely coalesce and form a tree-like pattern which is known as racemose
Neurocysticercosis, which when involve the pituitary gland many results in
multiple pituitary hormone deficiency.

9. Diagnosis:
NCC can be diagnosed by
 CT scan
 Stool examination
confirmatory tests include
 ELISA
 Immunoblotting techniques.
Treatment:
 Epileptic therapy
 Praziquantel
 Albendazol
 Surgical removal of brain cyst.

10. Prevention:
 Proper hand washing.
 Avoid contact with stool of infected person.
 Proper cocking of meat and meat products.
