BackgroundNeurocysticercosis occurs when the eggs of the pork tapeworm (Taenia solium) migrate and hatch into larvae within the central nervous system. Neurocysticercosis is the most common cause of seizures in the developing world and is characterized on brain imaging by cysts in different stages of evolution. In Canada, cases of neurocysticercosis are rare and most of these patients acquire the disease outside of Canada. We report the case of a patient with multiple intracranial lesions whose history and diagnostic imaging were consistent with neurocysticercosis. Pathological investigations ultimately demonstrated that her brain lesions were secondary to malignancy. Brain metastases are considered to be the most common cause of intracranial cystic lesions.Case presentationWe present the case of a 60-year-old Canadian-born Caucasian woman with a subacute history of ataxia, lower extremity hyper-reflexia, and otalgia who resided near a pig farm for most of her childhood. Computed tomography and magnetic resonance imaging showed that she had multiple heterogeneous intracranial cysts, suggestive of neurocysticercosis. Despite a heavy burden of disease, serological tests for cysticercosis were negative. This result and a lack of the central scolices on neuroimaging that are pathognomonic of neurocysticercosis prompted whole-body computed tomography imaging to identify another etiology. The whole-body computed tomography revealed right hilar lymphadenopathy associated with soft tissue nodules in her chest wall and abdomen. A biopsy of an anterior chest wall nodule demonstrated high-grade poorly differentiated carcinoma with necrosis, which stained strongly positive for thyroid transcription factor-1 and synaptophysin on immunohistochemistry. A diagnosis of stage 4 metastatic small cell neuroendocrine carcinoma was made and our patient was referred for oncological palliative treatment.ConclusionsThis case illustrates the importance of the diagnostic approach to intracranial lesions. Our patient’s diagnosis of neuroendocrine carcinoma was delayed because of her nontraditional presentation. Despite extensive metastatic burden, the lack of perilesional edema and the identification of lesions appearing to be in various stages of development led to a pursuit of neurocysticercosis as the diagnosis. The absence of constitutional symptoms should not discount the possibility of malignancy from the differential diagnosis.

“…L'examen TDM peut même être normal; dans notre étude, 05 cas (3,6%) de faux négatifs avaient été retrouvés, avec un examen TDM normal. Il s'agit là des principales indications de l'IRM à la recherche d'une forme intra-ventriculaire et parfois intra-parenchymateuse [ 17 ]. Il s'agit des formes classées stade I pour Duchene et al [ 12 ].…”

La cysticercose a une prévalence élevée dans les pays sub-sahariens et son diagnostic reste difficile. Cette étude a pour but de déterminer la valeur diagnostique de la tomodensitométrie dans la cysticercose cérébrale. Recrutement des patients ayant bénéficié d'une tomodensitométrie cérébrale dans l'une des circonstances suivantes: épilepsie, hypertension intracrânienne, syndrome pyramidal, détérioration mentale, ataxie locomotrice ou une diminution de l'acuité visuelle. Les critères de Del Brutto et al. avaient permis de retenir le diagnostic positif de cysticercose cérébrale. Pendant la période, 4193 patients avaient été inclus à l’étude, dont 140 cas de cysticercose cérébrale (3,3%). L’âge moyen des patients de cysticercose cérébrale était de 36 ± 14 ans, avec des extrêmes de 17 ans et 59 ans. La sensibilité et la spécificité de la tomodensitométrie dans la cysticercose cérébrale sont respectivement de 96,4% et 98,3%. La valeur prédictive positive et la valeur prédictive négative de la tomodensitométrie sont respectivement de 65,9% et 99,8%. Les aspects tomodensitométriques chez les vrais positifs sont dominés par des lésions associées, 72 cas (53,3%), suivies d'une hypodensité nodulaire arrondie unique ou multiple sans prise de contraste iodée, 17cas (12,6%). La TDM est une technique d'imagerie qui a une sensibilité et une spécificité élevées dans le diagnostic de la cysticercose cérébrale. Cependant, les autres critères de diagnostic restent utiles du fait de l'existence de nombreux cas de faux positifs à la tomodensitométrie.

“…Neurocysticercosis is a parasitic infection caused by the cysticerci of Taenia solium, primarily found in pork [3]. Upon ingesting undercooked or raw infected pork, humans become inadvertent hosts to the tapeworm larvae [4]. The larvae then migrate to various tissues, with the central nervous system being a prime target [5].…”

Intestinal Parasites - New Developments in Diagnosis, Treatment, Prevention and Future Directions [Working Title]

Neurocysticercosis presents a formidable global health challenge. This parasitic infection induces cystic lesions, primarily in the brain and spinal cord, leading to neurological symptoms and complications. Global prevalence varies, driven by socioeconomic conditions, cultural practices, and dietary habits, particularly in low and middle-income countries. Diagnosis remains challenging, relying on clinical, serological, and neuroimaging findings, with advanced tools like CT and MRI scans enhancing accuracy. Treatment strategies involve antiparasitic medications, anti-inflammatory drugs, and surgical interventions. Ongoing research explores innovative diagnostics and treatments, emphasising a comprehensive, individualised approach. A One Health approach, integrating human, animal, and environmental health, is crucial for effective prevention. Exploring the socioeconomic impacts, ethical considerations, and technology integration, including telemedicine, is paramount. Understanding cultural factors influencing healthcare-seeking behaviour contributes to culturally sensitive interventions. Technology integration can improve diagnostic capabilities and healthcare access, especially in regions with limited resources.
