Overview
Presenting symptoms differ according to the site of the cysticerci. Parenchymal neurocysticercosis causes all the symptoms and signs of space occupying lesions. Extraparenchymal neurocysticercosis causes manifestations of increased intracranial pressure if cysts are present in the subarachnoid space or in the ventricles, manifestations of spinal cord compression if present in the spinal cord or causes eye disease if cysts are present in the orbit.
History and Symptoms
Presenting symptoms vary 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.[1]
- Seizures: Most common manifestation of parenchymal neuroccysticercosis.[2]Seizers 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 [2]
Extraparenchymal:
1. Ocular cysticercosis:
- Symptoms depend on the exact site of infestation in the eye.
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.
3. Spinal cord cysticercosis: It is very rare (1.5-3% of all the cases).[3]The presentaion depends on the site of the lesion.
- Low back pain that may radiate down the legs
- Weakness in the legs and feet
- Loss of sensation in the legs and feet
- Bladder and bowel incontinence
- Sexual dysfunction
- Foot drop
- Decreased or absent reflexes in the legs
- Pain in the chest and/or back
- Loss of sensation below the level of the compression
- Paralysis of respiratory muscles
Extraneural
Muscular cysticercosis
- Can be asymptomatic and calcification discovered accidentally on imaging
- Muscle aches and weakness
Cutaneous cysticercosis
- Can be asymptomatic
- Discomfort, pruritis and excoriations
