“…1) One such route is the hemopoietic venous route, through retrograde blood flow via the inner vertebral venous plexus and the intervertebral veins. 36 2) A second possibility is the ventriculoependymal route; 9 during intraventricular hypertension the ependymal canal would dilate, allowing the cysticercus to migrate from the fourth cerebral ventricle into the spinal cord. Additionally, the ependymal canal is usually open until the 12th year of age in human or even continuing as such in older ages in some individuals, providing the small embryos a natural pathway into the spinal cord, before they transform into the 5-to 18-mm cysticerci.…”

“…6,8,9,13,20,26,33,36,37 Intradural spinal cysticercosis can be subdivided in leptomeningeal (subarachnoid) or intramedullary forms (parenchymal), the former being the most prevalent type of spinal parasitic infestation. In contrast to CNS lesions caused by the parasite Schistosoma mansoni, 41 in which the spinal cord is the principal site of damage, intramedullary involvement in cysticercosis is seldom observed, accounting for fewer than 20% of the intradural spinal cases.…”

Object The authors report their experience in the treatment of 12 symptomatic patients with intradural spinal neurocysticercosis. Methods The mean age of the 12 patients was 33 years. There were eight female and four male patients. Cysticercosis was present in association with hydrocephalus in nine cases. In nine of 12 patients the spinal lesion was confined to the thoracic or lumbar spinal cord, and in three the cysticerci occupied the cervical region. In all patients with hydrocephalus nerve root symptoms developed seven to 48 months later (mean 27.6 ± 15.5 months). In one patient hydrocephalus was absent, but he presented with cysticercal meningitis 24 months before spinal cord compression developed. Presenting symptoms suggesting spinal cysticercosis included muscular weakness (67%), pain (67%), and sphincter disturbance (25%). Neurological examination demonstrated a motor deficit in nine patients, sensory deficit in four, and radicular pain in three. The prognosis was worse in patients with moderate-to-severe arachnoiditis and spinal cord compression compared with those with isolated nerve roots involvement in whom outcome was favorable. Ten patients underwent laminectomy, after which neurological status improved in 44%, remained unchanged in 33%, or worsened in 22.2%. Conclusions The authors discuss their findings in these cases. Additionally they briefly review the literature, patho-physiology, and therapeutic and/or surgical strategies involved in this disease.

“…A primeira referência a cisticercose no canal raquídeo é atribuída a Rokitanski, em 1856. Até 1992 havia 97 casos de cisticercose espinhal descritos na literatura mundial, sendo apenas 33 intramedulares [1][2][3]5 . Atualmente são 45 os casos de cisticercose intramedular ( Tabela 1) 2 .…”

“…Assim, predomina a localização torá-cica (55,1%), seguida pela cervical (24,1%) e finalmente pela lombossacra (20,6%) 3 . A migração da larva inferiormente ao cérebro, para o espaço subaracnoideano 2 e a via hematogênica venosa 5 são hipóteses que tentam explicar a forma leptomeníngea. A disseminação hemato- gênica e a via ventriculo-ependimária têm sido postuladas como meios da larva atingir o interior da medula [1][2][3]5 .…”

RESUMO -A cisticercose é a doença parasitária que mais comumente envolve o sistema nervoso central. O acometimento espinhal varia de 0,7% a 5,8%, sendo que a forma intramedular é uma manifestação rara. Relatamos um caso de cisticercose intramedular ao nível de C4-C5, em paciente de 52 anos, feminina, atendida no serviço de Neurologia e Neurocirurgia da Santa Casa de Belo Horizonte. Foi submetida a tratamento cirúrgico para exérese da lesão, com boa evolução pós-operatória e recuperação progressiva dos déficits. Concluimos que apesar de patologia rara (foram encontrados 45 casos após revisão da literatura), deve entrar no diagnóstico diferencial de lesões medulares, especialmente em pacientes com história de neurocisticercose e naqueles que vivem ou procedem de regiões onde é a doença é endêmica.PALAVRAS-CHAVE: cisticercose, medula espinhal. Intramedular cysticercosis: case reportABSTRACT -Cysticercosis is the most ordinary parasitary disease involving the nervous system. The involvement of the spine is rare, ranging from 0.7% to 5.8%, and the intramedullary incidence is rather uncommon. We report the case of a 52-year-old female patient with intramedullary cysticercosis at the C4-C5 level, treated at the Neurology and Neurosurgery Service of Santa Casa de Belo Horizonte. The patient was operated with the complete exeresis of the lesion and had a good outcome. Forty-five cases of intramedullary cysticercosis were found in the literature review. We conclude that although it is a rare pathology, intramedullary cysticercosis should be included in the differential diagnosis of intramedullary lesions, mainly in cases of patients with previous diagnosis for neurocysticercosis and also of those who live in endemic areas. KEY WORDS: spinal cord, cysticercosis.A cisticercose (CI) é a doença parasitária que mais envolve o sistema nervoso central (SNC). O acometimento espinhal ocorre em 0,7% a 5,8% dos pacientes, sendo que a forma intramedular é uma rara manifestação [1][2][3][4][5] . Apesar de frequentemente estar associada à lesões cerebrais pode apresentarse isoladamente 1 . Pode ser classificada em: vertebral, extradural, leptomeníngea (subaracnóidea) e intramedular 2 , sendo a extradural de ocorrência excepcional, e as formas leptomeníngeas seis a oito vezes mais comuns que as intramedulares 3 .Tendo em vista a raridade dessa patologia, decidimos pelo relato do presente caso, analisando aspectos patogênicos, clínicos, radiológicos e terapêuticos da doença, através de revisão da literatura.
