Cysticercosis
Organism: Taenia Solium
Symptoms
Any one or combination of: seizures, focal neurological deficit, headache, hydrocephalus, arachnoiditis, chronic meningitis, encephalitis.
Diagnosis
bulletImaging study: CT, MRI, showing punctate calcifications or fluid filled cystic lesions. Edema or enhancement of the cyst suggest active disease.
bulletSerum Cysticercosis Antibody: high percentage of false positive for patients from endemic area (?30%)
bulletCSF ELISA for the detection of anticysticercal antibodies is accurate when performed in patients with active meningeal disease. The test is most often negative in those with inactive neurocysticercosis or in those with parenchymal cysts.
Treatment
bulletNeed eye examination prior to treatment
bulletTherapy must be individualized.
bulletCalcified lesions should only receive symptomatic treatment.
bulletPatients with parenchymal or subarachnoid cysts should be treated with Cysticidal drugs. (see below)
bulletPatients with ventricular cysts may also be treated with albendazole; however, endoscopic removal is the current approach to these lesions.
bulletCysticidal drugs may exacerbate the brain edema associated with cysticercotic encephalitis and are contraindicated in this form of the disease.
bulletIn these cases, dexamethasone (16 mg/day) and mannitol (100 ml every 6 hours) are advised for the management of intracranial hypertension.
bulletCorticosteroids are also indicated as the primary form of therapy for patients with cysticercotic angiitis, arachnoiditis, and to prevent secondary reactions related to the use of cysticidal drugs.
bulletCysticidal drugs: both doses and duration of therapy are controversial.
bulletPraziquantel (3 doses of 25 to 30 mg/kg given every 2 hours). 
bulletComes in 600 mg. cost $200 for 18 tabs.
bullet May cause headache, dizziness and GI upset.
bulletThe tablets should be washed down unchewed with some liquid during meals. Keeping the tablets in the mouth can reveal a bitter taste which can promote gagging or vomiting.
bulletAlbendazole (15 mg/kg/day for one week)
bulletComes in 200 mg tab, given BID. 
bulletCost about $60 for 36 tab.
bulletLonger steroid treatment may be needed for vasculitis, arachnoiditis.
bulletTreat seizure with the usual anticonvulsant.
bulletHydrocephalus: VP shunt
