Abstract
Author reports the case of a 28 years-old woman presenting episodes of paresthesia of the right arm with duration of approximately 4 days which remitted spontaneously, followed after two years by episodes of right hemiparesthesia. Brain MRI followed by brain stereotactic biopsy established the diagnosis of neurocysticercosis. Since electroencephalography showed no spike-wave abnormalities it was difficult to establish if symptoms were secondary to parietal lesion itself or were focal sensory seizures. After treatment with albendazole, methylprednisolone and sodium valproate the patient had a good recovery.
Highlights
Neurocysticercosis is the most common helminthic infection affecting the central nervous system of humans being caused by Taenia solium
(1) Diversity of clinical manifestations of neurocysticercosis is related to differences in the number and location of the lesions within the nervous system and to the intensity of the host’s immune response against the parasites
A sizable proportion of those cysts have in their interior an eccentric hyperdense nodule representing the scolex, giving them ‘‘hole-with-dot’’ appearance, which is pathognomonic of neurocysticercosis
Summary
Neurocysticercosis is the most common helminthic infection affecting the central nervous system of humans being caused by Taenia solium. In the usual cycle of transmission, a few gravid proglottids from the adult tapeworm – attached to the intestinal wall of humans – are passed every few days with feces.
