History and Symptoms
Presenting symptoms vary with according to the site of infestation:
Neurocysticercosis
Parenchymal:
Many cases (up to 80%) can remain asymptomatic and discovered either in autopsies or accidentally during routine imaging. 19
- Seizures: Most common manifestation of parenchymal neuroccysticercosis.20Seizers can be focal, generalized or focal with secondary generalization.
- Headache
- Nausea and vomiting
- Psychiatric disorders: has a wide variatoin from abnormal dysfunction and up to dementia (20)
Extraparenchymal:
1. Ocular cysticercosis:
Symptoms depend on the exact site of infestation in the eye. Retinal and subretinal infestaion have the worst prognosis and are the most difficult to treat.
2. Extraparenchymal in the brain ventricles and subarachnoid space:
Cysticerci obstruct of the flow of the CSF and cause hydrocephalus. Symptoms usually result from increased intracranial pressure.
- Headache
- Nausea and vomiting
- Decreased visual acuity
- Seizures
3. Spinal cord cysticercosis:
It is very rare (1.5-3% of all the cases). (21)The resentaion depends on the site of the lesion.
- Paraesthesia
- radicular pain
- Muscular weakness due to LMN lesions
Extraneural cysticercosis:
Cutanuous:
May be asymtomatic Irritation and disfigurement by the nodules
Muscular:
Asymptoamtic Muscle aches and weakness
