From the Guidelines
Management of patients with multiple calcifications consistent with remote neurocysticercosis exposure typically does not require antiparasitic treatment, as these calcifications represent dead parasites, and the primary management approach focuses on symptom control, particularly seizures if present. The evidence from the 2017 clinical practice guidelines by the Infectious Diseases Society of America (IDSA) and the American Society of Tropical Medicine and Hygiene (ASTMH) 1 supports this approach, indicating that antiparasitic treatment is not recommended for calcified parenchymal neurocysticercosis.
Key Considerations
- Antiepileptic therapy is crucial for patients with seizures, with medications such as levetiracetam, carbamazepine, or lamotrigine being appropriate choices, depending on patient factors and potential side effects 1.
- Treatment duration for antiepileptic drugs varies, with some patients requiring lifelong therapy and others potentially being weaned off after remaining seizure-free for 1-2 years.
- Regular neurological follow-up is recommended every 6-12 months, with repeat imaging only if new symptoms develop.
- Patient education about seizure precautions and triggers is essential.
Evidence Summary
The guidelines from the IDSA and ASTMH 1 emphasize the importance of symptom control and provide recommendations for antiepileptic and anti-inflammatory therapy. The evidence suggests that calcified lesions represent the end stage of infection, where the parasite is no longer viable, making antiparasitic treatment unnecessary and potentially harmful due to inflammatory reactions that could worsen neurological symptoms.
Management Approach
Given the evidence, the management approach for patients with multiple calcifications consistent with remote neurocysticercosis exposure should prioritize symptom control, particularly for seizures, and avoid unnecessary antiparasitic treatment, unless there is evidence of viable cysts. This approach is supported by the most recent and highest quality studies, including those from 2018 1.

Management Plan for Neurocysticercosis
The management plan for a patient with multiple cortical or peripheral calcifications consistent with remote cysticercosis (neurocysticercosis) exposure involves several key considerations:
- Antiparasitic Treatment: Antiparasitic drugs such as albendazole and praziquantel have been shown to be effective against cysticercosis 2. Albendazole is possibly more effective in subarachnoidal, ventricular, and spinal forms of cysticercosis.
- Corticosteroids: Concomitant corticosteroids should be administered to minimize the risks of anticysticercal treatment, especially if there is a massive parasitic load 2.
- Seizure Control: Antiepileptic medications may be necessary to control seizures, which are a common symptom of neurocysticercosis 3, 4.
- Surgical Intervention: Ocular and extraocular muscle cysticercosis may require surgical intervention, while skeletal muscle cysts are surgically removed only if painful 3.
- Follow-up: Patients with neurocysticercosis should have regular follow-up appointments to monitor the progression of the disease and adjust treatment as necessary 4.
Treatment Options
Treatment options for neurocysticercosis include:
- Albendazole: A 2-week course of albendazole therapy has been shown to be effective in treating solitary cerebral cysticercosis 4.
- Praziquantel: Praziquantel has been used to treat neurocysticercosis, but its effectiveness is still debated 2, 5.
- Combined Treatment: The combined use of albendazole and praziquantel may improve clearance of brain parasites, but more research is needed to confirm its effectiveness 5.
