Neurocysticercosis: a rare cause of new-onset seizures

Neurocysticercosis, a prevalent helminthic infection of the central nervous system, is primarily transmitted through the faeco-oral route via contaminated water or vegetables. The revised diagnostic criteria (2017) provide a standardized framework for categorizing cases based on diagnostic certainty and diagnostic criteria. Neuroimaging modalities, computed tomography (CT) and magnetic resonance imaging (MRI), are the gold standard for diagnosis. We report a case of an immunocompetent patient residing in an endemic region with minimal exposure to risk factors, who presented with new-onset seizures. Neurocysticercosis was diagnosed based on radiological evidence of a single enhancing lesion with the characteristic "hole-with-dot" appearance. The patient received anti-inflammatory, antiepileptic, and analgesic medications, followed by antiparasitic treatment. Clinical improvement was observed with resolution of perilesional edema and successful seizure control.
