Colloidal/Calcified at University Hospital of KSA: A Case Series.

BACKGROUND

Neurocysticercosis (NCC) is considered the most common central nervous system (CNS) helminthic infection. The prevalence of NCC cases in the Middle East has increased in recent years. Thirty-nine cases of NCC were reported between 2003-2011 in the Arabian Peninsula, among, five cases being from the kingdom Saudi Arabia (KSA). Most of the cases reported from the KSA were presented with seizures, and they belonged to expatriate workers or their related contacts. In this case series, we presented three cases of colloidal/calcified NCC.

CASES

Our patients were diagnosed with NCC based on epidemiologic exposure, clinical features, and typical radiological findings. Stool samples for ova and parasites were negative in all three cases. Among these cases, two patients were immigrants and belonged to endemic areas, and third case who is the youngest in this series was a Saudi, without any history of exposure to any source.

RESULTS

The first and the third cases were treated with Albendazole and Dexamethasone. We did not offer any medication regarding NCC in the second case as he had asymptomatic NCC and the disease was inactive so did not mandate anti-helminth medication.

CONCLUSION

NCC in KSA, like in non-endemic countries, is not a rare or unusual infection anymore, presenting with seizures or incidental findings in an asymptomatic state. Vigilant diagnostic protocols with efficient diagnostic tools are required for detecting carriers of the adult form of the parasite. Timely detection of these carriers can avoid further spread and its related complications in the Saudi population.
