Case Report: Three Cases of Neurocysticercosis in Central Africa

Neurocysticercosis in a Nigerian woman -missed diagnosis of a neglected disease and surgical management

Neurocysticercosis is a rarely diagnosed but significant clinical problem from infestation with taenia solium. It occurs as a result of ingestion of infested pork and the mode of transmission is usually feco-oral. It is commonly associated with non-specific neurologic manifestations expected of intracranial space-occupying lesions with its most common neurological presentation being seizures. However, its diagnosis without seizure is rarely reported. We report a recent experience in this regard and outcome of this disease which was inadvertently managed surgically. A good history and high index of suspicion especially in developing and low socioeconomic region is helpful for diagnosis in the presence of appropriate radiological findings. Prognosis is good when treatment is tailored to well selected cases. Treatment options include medical with or without surgical removal of encapsulated cyst. A high index of suspicion will be helpful in making appropriate diagnosis and proper management of this disease.

Unmasking a Hidden Culprit: Neurocysticercosis, an Overlooked Cause of Acquired Epilepsy

Neurocysticercosis (NCC) is a common parasitic brain infestation caused by the ingestion of Taenia solium eggs, predominantly in developing countries. In this report, we presented the case of a 44-year-old woman who exhibited stroke symptoms and had a decade-long history of recurrent headaches and epilepsy. At presentation, a non-contrast computed tomography scan of the brain was performed and revealed hypodense oval lesions and calcified cysts in both cerebral hemispheres, strongly indicative of NCC. The patient responded positively to treatment with dexamethasone, albendazole, and carbamazepine. This case study underscores the importance of neuroimaging in investigating patients with neurological conditions like epilepsy, especially in developing countries. Early diagnosis and effective treatment are crucial in preventing and controlling NCC, reducing its impact on public health.

The prevalence of and contributors to neurocysticercosis in endemic regions

BACKGROUND

Neurocysticercosis is one of the most common causes of acquired epilepsy worldwide. Caused by Taenia solium, the infection uses pigs as an intermediate host and thus is often associated with proximity to and consumption of pigs.

OBJECTIVE

This review explores the epidemiology of neurocysticercosis in endemic regions across Africa, Asia, and Latin America and examines common risk factors in these areas.

METHODS

A literature review was conducted using pubmed to search for articles with key words including neurocysticercosis, Taenia, solium, epidemiology, and the names of countries and continents in the regions of interest.

FINDINGS

Multiple risk factors for neurocysticercosis were identified, including inadequate regulation of pig farms and food safety, poor sanitation, and water contamination. In addition, additional barriers to appropriate diagnosis and management were found, including resource limitations and poor health literacy.

CONCLUSION

Despite its global prevalence, effective limitation of neurocysticercosis is still achievable through projects which address common risk factors.
