Neurocysticercosis Transmission and Clinical Management

Introduction to Neurocysticercosis

The mode of transmission of neurocysticercosis is through the faecal-oral route by ingestion of Taenia solium eggs, according to the Centers for Disease Control and Prevention (CDC) 1, 2, 3, 4

Patients with neurocysticercosis often present with progressive headaches and seizures, particularly in young adults from rural endemic areas, as noted by the World Health Organization (WHO) 3, 4
CT findings typically show intraparenchymal cysts with central hyperdensity, representing the scolex, as described by the American Society of Neuroradiology 5
CSF analysis may reveal eosinophilic pleocytosis, present in approximately 20% of neurocysticercosis cases, with lymphocytosis and elevated protein, according to the Infectious Diseases Society of America (IDSA) 1, 2

Endemic regions for neurocysticercosis include South and Southeast Asia, Central and South America, and Africa, as reported by the WHO 1, 2, 3
The incubation period averages 3.5 years, ranging from months to over 10 years, from egg ingestion to symptom onset, according to the CDC 3, 4
In endemic villages, approximately 10-20% of individuals show CT evidence of neurocysticercosis, as noted by the WHO 3

Serology with enzyme-linked immunotransfer blot (EITB) is used for confirmation, as recommended by the IDSA 5
MRI brain with contrast is more sensitive than CT for scolex visualization and subarachnoid involvement, according to the American College of Radiology 5
Stool microscopy of patients and household contacts can identify tapeworm carriers, as described by the WHO 3, 4

The treatment approach includes albendazole 400 mg twice daily for 14 days with dexamethasone starting one day before antiparasitic therapy, as recommended by the IDSA 1, 2, 3, 4
Antiepileptic drugs are used for seizure management, according to the American Academy of Neurology 5
Monitoring for hydrocephalus development requiring neurosurgical intervention is crucial, as noted by the WHO 3
