Hemiparesia súbita secundaria a cisticercosis cerebral: presentación de un caso clínico / Sudden hemiparesis secondary to cerebral cysticercosis: presentation of a clinical case

Introducción: La neurocisticercosis es una infección parasitaria del sistema nervioso central, ocasionada por la etapa larval del parásito Taenia solium. Su prevalencia mundial es de 9,1%. Se presenta a continuación un caso clínico en el que destaca una clínica infrecuente y tamaño de la lesión poco común; caso que fue resuelto con éxito mediante neurocirugía. Presentación del caso: Hombre de 48 años, residente en localidad rural, consultó por cuadro súbito de hemiparesia derecha de predominio crural, posteriormente con aumento de paresia braquial ipsilateral. Al examen físico destacó síndrome piramidal derecho. Se estudió con Tomografía Computarizada que evidenció quiste frontal izquierdo con compresión del área motora, sugerente de lesión parasitaria. Resonancia Nuclear Magnética de Cerebro (RNMC) informó proceso expansivo quístico fronto-parietal parasagital izquierdo de 5 x 5,5 cm, con efecto de masa. Por tamaño, tipo de lesión y clínica se decidió realizar cirugía abierta con extirpación total y biopsia que informó cisticercosis cerebral. El paciente evolucionó con recuperación total de su déficit motor posterior a la cirugía. Discusión: La neurocisticercosis se encuentra dentro de los diagnósticos diferenciales de lesiones quísticas encefálicas. Su clínica es inespecífica, manifestándose comúnmente con convulsiones y cefalea. La RNMC permite el diagnóstico y localización de las lesiones. El tratamiento es médico, quirúrgico o combinado. Generalmente, el manejo se basa en antiepilépticos y antiparasitarios sistémicos, sin embargo en este caso, se decidió el manejo quirúrgico que llevó a una mejoría total del paciente, lo que avala la cirugía precoz como principal medida en lesiones de este tipo

Introduction: Neurocysticercosis is a parasitic infection of the central nervous system, caused by the larval stage of the parasite Taenia solium. Its worldwide prevalence is 9.1%. We present below a clinical case with an infrequent clinical and uncommon lesion size, with surgical resolved. Case report: A 48 year old man, who was a resident of a rural locality, consulted for sudden hemiparesis on the right side of the crural predominance, subsequently with increased ipsilateral brachial paresis. Physical examination highlighted right pyramidal syndrome. It was studied with Computed Axial Tomography that showed left frontal cyst with compression of the motor area, suggestive of parasite lesion. Brain Nuclear Magnetic Resonance (BNMR) reported left parasagittal fronto-parietal cystic expansive process of 5 x 5.5 cm, with mass effect. By size, type of lesion and clinic it was decided to perform open surgery with total extirpation and biopsy that reported cerebral cysticercosis. The patient evolved with complete recovery of motor deficit after surgery. Discussion: Neurocysticercosis is a differential diagnosis of brain cystic lesions. Its clinic is non-specific, commonly manifesting with seizures and headache. The RNMC allows the diagnosis and location of the lesions. The treatment is medical, surgical or combined. Usually, the management is based on antiepileptics and systemic antiparasitic, however in this case, it was decided the surgical management that led to the total improvement of the patient, which guarantees the early surgery as the main measure in lesions of this type

Neurocisticercosis racemosa subaracnoidea gigante y ventricular: a propósito de un caso / Giant racemose subarachnoid and intraventricular neurocysticercosis: A case report

La neurocisticercosis es la enfermedad parasitaria más frecuente del sistema nervioso central. Es causada por las larvas de Taenia solium, las cuales pueden estar alojadas en distintas localizaciones anatómicas. En países como España existe una prevalencia en ascenso debido, principalmente, a la inmigración desde regiones endémicas. Las formas extraparenquimatosas son menos frecuentes, pero más graves por su tendencia a producir complicaciones. La neuroimagen desempeña un papel primordial en el diagnóstico y seguimiento de esta enfermedad, apoyada en la serología y un contexto clínico-epidemiológico compatible. El tratamiento de elección son los fármacos cisticidas albendazol y praziquantel, habitualmente se asocian a estos corticoides y, cuando corresponde, la cirugía. Se presenta un caso de neurocisticercosis con afectación simultánea intraventricular y subaracnoidea en su forma racemosa gigante.

Neurocysticercosis is the most frequent parasitic disease of the central nervous system. It is caused by the larvae of Taenia solium, which can affect different anatomical sites. In Spain there is an increasing prevalence mainly due to immigration from endemic areas. The extraparenchymal forms are less common, but more serious because they usually develop complications. Neuroimaging plays a major role in the diagnosis and follow-up of this disease, supported by serology and a compatible clinical and epidemiological context. First-line treatments are cysticidal drugs such as albendazole and praziquantel, usually coadministered with corticosteroids, and in some cases surgery is indicated. We here report a case of neurocysticercosis with simultaneous intraventricular and giant racemose subarachnoid involvement.

Clinical features, radiological characteristics, and pathological changes in 42 patients with cerebral sparganosis / 中华神经科杂志

Objective To investigate the clinical features,the radiological characteristics,and the pathological changes of cerebral sparganosis.Methods We retrospectively collectted and summarized the clinical data of 42 patients with cerebral sparganosis from the Iinstitute of Anti-parasitic Diseases of Jiangxi Province and the First Affiliated Hospital of Nanchang University during January 2000 to January 2014.The follow-up period of the 42 patients ranged from 4 to 96 months.Results Forty-two cases (30 males and 12 females) with cerebral sparganosis were enrolled in the study.Among the 42 patients,34 cases suffered from seizures,16 cases experienced headaches,and 14 cases had limb weakness.The brain CT scan showed the small and punctuate calcifications scattering around the lesions in 18 cases.The features of enhanced MRI included aggregating ring-like enhancement in 38 cases,tunnel lesions in 14 cases,and lesion migration in 13 cases.Twenty-four of the 42 patients were performed surgery.The brain tissues revealed multiple inflammatory tunnels,in which live or degenerated larvae were identified in 20 cases,but only eosinophilia tunnels were observed in the other 4 cases.The serum and cerebro-spiral fluid specimens from 18 patients without surgery were positive to spirometra mansoni antigen.Their cerebral lesions disappeared and got a favorable prognosis after administration of praziquantel in long term follow-ups.Conclusions There is a high incidence of cerebral sparganosis in Poyang lake basin.The clinical features of cerebral sparganosis mainly include seizure,headache and hemiparesis.The enhanced lesions show knot or tunnel signs on multi-planar MRI which are associated with the multiple inflammatory tunnels of larvae migration.A longterm administration of high dose opraziquantel can also get a good treatment prognosis without the classical surgical therapy for cerebral sparganosis.
