ABSTRACT

La hidrocefalia es una condición clínica que consiste en un cúmulo de líquido cefalorraquídeo a nivel encefálico. Una de las causas, poco frecuente, es el síndrome de Dandy-Walker. Se presenta el caso de un recién nacido con diagnóstico prenatal de hidrocefalia secundaria a una malformación de Dandy-Walker y sospecha de genitales ambiguos. Tras el nacimiento, se confirma el diagnóstico prenatal de malformación de Dandy-Walker asociado a manifestaciones extracraneales poco frecuentes como hipospadias interescrotal y dilatación del seno coronario secundario a persistencia de la vena cava superior izquierda. Con este caso clínico queremos exponer la complejidad del síndrome de Dandy-Walker debido a sus múltiples asociaciones, que marcarán el pronóstico del paciente y la necesidad de tratamiento multidisciplinar.


Hydrocephalus is a clinical condition that consists of an accumulation of cerebrospinal fluid around the brain; Dandy-Walker syndrome is a rare cause of it. We present the case of a newborn with prenatal diagnose of hydrocephalus due to a Dandy-Walker malformation, as well as ambiguous genitalia. After birth, diagnosis of Dandy-Walker malformation associated with uncommon extracranial manifestations is confirmed. Specifically, the baby presents interscrotal hypospadias and coronary sinus dilatation due to the persistence of the left superior vena cava. With the exposition of this case, we bring out the complexity of the Dandy-Walker syndrome due to the malformations associated with it; the ones that will determine the prognosis and the need of a multidisciplinary treatment

ABSTRACT

ABSTRACT Dandy-Walker Syndrome Variant presents itself as a milder form of Dandy-Walker Syndrome, with less pronounced vermis hypoplasia, and hearing impairment is among its characteristics. This study aimed to report the case of a male patient aged 4.5 clinically diagnosed with Dandy-Walker Syndrome variant, a cochlear implant user, who was referred to rehabilitation services and followed up by a multidisciplinary team. The patient underwent therapy assisted by an audiologist/speech therapist and a physiotherapist between June 2016 and December 2016, totaling 20 sessions, with emphasis on the Aurioral approach. His evolution regarding hearing and motor abilities was evaluated through standardized instruments that helped to catalogue the patient's evolution and responses in an empirical way. The development of his auditory and motor skills, evaluated through standardized tests used as parameters of therapeutic evolution, demonstrated that rehabilitation, performed by a multi-professional team, can be satisfactorily applied in the management of cases where deafness does not appear as the only associated factor. It is suggested that a cochlear implant, despite the difficulties peculiar to the syndrome in question, can be an effective resource to acquire oral language and reach more complex stages related to hearing and language skills.


RESUMO A Variante da Síndrome de Dandy-Walker apresenta uma forma mais branda em relação à Síndrome de Dandy-Walker, sendo a hipoplasia do vermes menos acentuada e dentre suas características, a deficiência auditiva. O estudo objetivou relatar o caso de um paciente do sexo masculino, 4:5 anos, quadro compatível com Variante da Síndrome, usuário de implante coclear, referenciado ao serviço de reabilitação com equipe multidisciplinar. Foi inserido em terapia com fonoaudiólogo e fisioterapeuta, no período entre julho a dezembro de 2016, totalizando 20 sessões, com ênfase na abordagem Aurioral. Avaliou-se sua evolução quanto às habilidades auditivas e motoras, por meio de instrumentos padronizados que auxiliaram na catalogação da evolução e das respostas do paciente de maneira empírica. O desenvolvimento das habilidades auditivas e motoras, avaliadas por meio de testes utilizados como parâmetros de evolução terapêutica demonstraram que a reabilitação, realizada em equipe multiprofissional, pode ser aplicada satisfatoriamente no gerenciamento de casos em que a surdez não aparece como único fator. Sugere-se que o implante coclear, apesar das dificuldades peculiares à síndrome, pode ser um recurso eficiente para aquisição da linguagem oral e alcance de etapas mais complexas relacionadas às habilidades auditivas e de linguagem.

ABSTRACT

Se presentó un paciente de sexo femenino de 13 años, con antecedentes aparentes de salud, que comenzó con parestesias intermitentes, sensación de hormigueo en la parte medial de la cara, disminución de la fuerza muscular en el lado izquierdo del cuerpo; acudió al Servicio de Imagenología del Centro de Alta Tecnología de CHUAO, Caracas, Venezuela y se le realizó resonancia magnética para estudio de cráneo con secuencias Flair en secuencias coronales, T1 en secuencias sagitales, T2 axiales. La resonancia mostró una dilatación quística del IV ventrículo con agrandamiento ligero de la fosa posterior y elevación del tentorio e hipoplasia del vermis cerebeloso que concordó con una malformación de Dandy Walker, la intensidad de señales y morfología de las estructuras supratentoriales eran normales. No se apreciaron alteraciones en la región selar, ni supraselar. Se remitió a Consulta de Neurocirugía para evaluar tratamiento quirúrgico.


A 13-year-old female patient with an apparent health history, which began with intermittent paresthesias, tingling sensation in the medial part of the face, decreased muscle strength in the left side of the body is presented, the patient underwent magnetic resonance imaging to study skull with Flair sequences in coronal sequences, sequences Sagittal T1, T2 axial at the Imaging Service Center for High Technology Chuao, Caracas, Venezuela. The resonance showed a cystic dilatation of the IV ventricle with slight enlargement of the posterior fossa and elevation of the tentorium and cerebellar vermis hypoplasia that agreed with a Dandy Walker malformation, signal intensity and morphology of the supratentorial structures were normal. No alterations were observed in the sellar or suprasellar region. The patient was referred to Neurosurgery Consultation to evaluate surgical treatment.

Esta condición se caracteriza por agenesia o hipoplasia del vermis cerebeloso, dilatación quística del cuarto ventrículo y alargamiento de la fosa posterior. Aproximadamente el 80% de los pacientes presenta hidrocefalia. La triada característica de la malformación de Dandy-Walker que consiste: agenesia parcial o completa del vermis, dilatación quística del cuarto ventrículo y alargamiento de la fosa posterior. El diagnóstico prenatal es preferible realizarlo luego de las 18 semanas, el postnatal se hace con ultrasonido transfontanelar, resonancia magnética y tomografía axial computarizada. El tratamiento de esta patología está basado en el manejo de la hidrocefalia. 1 Caso: a continuación presentamos un caso clínico de Dandy Walker de la Unidad de Medicina Materno Fetal del Hospital Carlos Andrade Marín de Quito.


Introduction: Dandy-Walker malformation is a rare congenital disease involving the cerebellum and the fourth ventricle. This condition is characterized by agenesia or hypoplasia of the cerebellar vermis, cystic dilatation of the fourth ventricle, and enlargement of the posterior fossa. Approximately 80% of patients have hydrocephalus. Dandy-Walker malformation was described by Dandy and Blackfan in 1914. The characteristic triad of Dandy-Walker malformation is consisting of complete or partial agenesis of the vermis, cystic dilatation of the fourth ventricle and an enlarged posterior fossa. The prenatal diagnosis of Dandy-Walker malformation is better after 18 weeks of gestation. After birth it is best diagnosed with the help of transfontanelar ultrasound, magnetic resonance imaging, and computerized axial tomography. The treatment for this condition is based in the management of hydrocephalus. 1 Case: below is a case report of Dandy Walker at the Maternal Fetal Medical Unit of the Carlos Andrade Marin Hospital in Quito.

ABSTRACT

OBJECTIVE: Blake's pouch cyst (BPC) is a midline cystic malformation of the posterior fossa, within Dandy-Walker's complex (DWC), often associated with hydrocephalus. Endoscopic third ventriculostomy (ETV) has been an alternative to conventional methods for BPC treatment. This study aimed at reporting our experience with ETV in a series of patients with BPC. METHODS: Of 33 patients diagnosed with midline posterior fossa cyst, 26 met the protocol criteria for DWC, and eight subjects with BPC were selected (aged one month to two years old). All cases were treated with ETV. RESULTS: Five patients were male; and three were prenatally diagnosed. They had hydrocephalus and motor deficiencies. Motor assessment at a five-year follow-up yielded normal findings. All patients improved, and only one had residual cognitive dysfunction, despite overall neurological improvement. There were no complications. CONCLUSIONS: ETV was a safe and effective procedure, reducing risks and morbidity associated with open surgery and shunt-related problems. .


OBJETIVO: O cisto da bolsa de Blake (CBB) é uma malformação cística mediana da fossa posterior, dentro do complexo de Dandy-Walker (CDW), frequentemente associada à hidrocefalia. A terceiroventriculostomia endoscópica (TVE) tem sido considerada uma alternativa aos métodos convencionais de tratamento do CBB. Este estudo teve como objetivo relatar nossa experiência com TVE em uma série de pacientes com CBB. MÉTODOS: Dos 33 pacientes diagnosticados com cisto mediano da fossa posterior, 26 preencheram os critérios do protocolo para CDW, dos quais oito foram selecionados com CBB (idades variando entre um mês a dois anos). Todos os casos foram tratados com TVE. RESULTADOS: Cinco pacientes eram do sexo masculino, três tiveram diagnóstico no pré-natal; e todos apresentavam hidrocefalia e alterações motoras. A avaliação motora após cinco anos apresentou resultados normais. Todos os pacientes melhoraram, e apenas um apresentou um leve déficit cognitivo, apesar da melhora neurológica geral. Não houve complicações. CONCLUSÕES: A TVE foi um procedimento seguro e eficaz, reduzindo riscos e morbidade associados à cirurgia aberta e a problemas relacionados aos shunts.

ABSTRACT

Introduction: Dandy Walker Syndrome is a congenital abnormality in the central nervous system, characterized by a deficiency in the development of middle cerebelar structures, cystic dilatation of the posterior pit communicating with the fourth ventricle and upward shift of the transverse sinuses, tentorium and dyes. Among the clinical signs are occipital protuberances, a progressive increase of the skull, bowing before the fontanels, papilledema, ataxia, gait disturbances, nystagmus, and intellectual impairment. Objectives: To describe a case of female patient, 13 years old with a diagnosis of this syndrome and bilateral hearing loss underwent cochlear implant surgery under local anesthesia and sedation. Case Report: CGS, 13 years old female was referred to the Otolaryngological Department of Otolaryngology Institute of Parana with a diagnosis of "Dandy-Walker syndrome" for Otolaryngological evaluation for bilateral hearing loss with no response to the use of hearing aids. Final Comments: The field of cochlear implants is growing rapidly. We believe that the presence of Dandy-Walker syndrome cannot be considered a contraindication to the performance of cochlear implant surgery, and there were no surgical complications due to neurological disorders with very favorable results for the patient who exhibits excellent discrimination. It has less need for lip reading with improvement in speech quality...

ABSTRACT

Alrededor de 1 por cada 1 000 recién nacidos presenta algún tipo de alteración cráneo encefálica, constituyen el 15 por ciento de todas las malformaciones. El Síndrome de Dandy-Walker constituye el espectro de trastornos, resultantes de un desarrollo anómalo del cerebelo asociado con una alteración en el desarrollo del cuarto ventrículo. Constituye una malformación congénita poco frecuente. Se pretende resaltar la importancia del diagnóstico precoz por ultrasonografía de malformaciones congénitas en el nivel primario de atención médica. Se presenta el diagnóstico prenatal, por ultrasonido, de un caso que a las 20 sem de gestación se le observaron imágenes ecolúcidas en el feto ubicadas a nivel del cerebelo, 4to ventrículo y atrium ventricular lo que hizo sospechar de inmediato en el diagnóstico de un Síndrome de Dandy Walker, sin otra alteración demostrable en este tiempo de embarazo. Previo asesoramiento genético, la pareja decidió la terminación del embarazo. El caso fue confirmado por Anatomía patológica y no se encontraron otras malformaciones asociadas


Around one by each 1 000 newborns has some type of encephalic skull alteration accounting for the 15 percent of all the malformations. The Dandy-Walker syndrome is the disorder spectrum, resulting from an anomalous cerebellum development associated with an alteration in the four ventricle development. It is an uncommon congenital malformation. Authors try to emphasize on the significance of the ultrasonography in the early diagnosis of congenital malformations at medical care primary level. Authors present the US prenatal diagnosis of a patient that at 20 weeks of pregnancy with fetal echo-lucid images located at cerebellum level, fourth ventricle and ventricular atrium arousing immediate suspect of Dandy-Walker diagnosis without other alterations present at this pregnancy stage. With a previous genetic advice, couple took the decision of end the pregnancy. This case was confirmed by a pathologic anatomy study without other associated malformation

ABSTRACT

A síndrome do X Frágil é a causa mais frequente de deficiência intelectual hereditária. A variante de Dandy-Walker trata-se de uma constelação específica de achados neurorradiológicos. Este estudo relata achados da comunicação oral e escrita de um menino de 15 anos com diagnóstico clínico e molecular da síndrome do X-Frágil e achados de neuroimagem do encéfalo compatíveis com variante de Dandy-Walker. A avaliação fonoaudiológica foi realizada por meio da Observação do Comportamento Comunicativo, aplicação do ABFW - Teste de Linguagem Infantil - Fonologia, Perfil de Habilidades Fonológicas, Teste de Desempenho Escolar, Teste Illinois de Habilidades Psicolinguísticas, avaliação do sistema estomatognático e avaliação audiológica. Observou-se: alteração de linguagem oral quanto às habilidades fonológicas, semânticas, pragmáticas e morfossintáticas; déficits nas habilidades psicolinguísticas (recepção auditiva, expressão verbal, combinação de sons, memória sequencial auditiva e visual, closura auditiva, associação auditiva e visual); e alterações morfológicas e funcionais do sistema estomatognático. Na leitura verificou-se dificuldades na decodificação dos símbolos gráficos e na escrita havia omissões, aglutinações e representações múltiplas com o uso predominante de vogais e dificuldades na organização viso-espacial. Em matemática, apesar do reconhecimento numérico, não realizou operações aritméticas. Não foram observadas alterações na avaliação audiológica periférica. A constelação de sintomas comportamentais, cognitivos, linguísticos e perceptivos, previstos na síndrome do X-Frágil, somada às alterações estruturais do sistema nervoso central, pertencentes à variante de Dandy-Walker, trouxeram interferências marcantes no desenvolvimento das habilidades comunicativas, no aprendizado da leitura e escrita e na integração social do indivíduo.


The Fragile X syndrome is the most frequent cause of inherited intellectual disability. The Dandy-Walker variant is a specific constellation of neuroradiological findings. The present study reports oral and written communication findings in a 15-year-old boy with clinical and molecular diagnosis of Fragile X syndrome and neuroimaging findings consistent with Dandy-Walker variant. The speech-language pathology and audiology evaluation was carried out using the Communicative Behavior Observation, the Phonology assessment of the ABFW - Child Language Test, the Phonological Abilities Profile, the Test of School Performance, and the Illinois Test of Psycholinguistic Abilities. Stomatognathic system and hearing assessments were also performed. It was observed: phonological, semantic, pragmatic and morphosyntactic deficits in oral language; deficits in psycholinguistic abilities (auditory reception, verbal expression, combination of sounds, auditory and visual sequential memory, auditory closure, auditory and visual association); and morphological and functional alterations in the stomatognathic system. Difficulties in decoding the graphical symbols were observed in reading. In writing, the subject presented omissions, agglutinations and multiple representations with the predominant use of vowels, besides difficulties in visuo-spatial organization. In mathematics, in spite of the numeric recognition, the participant didn't accomplish arithmetic operations. No alterations were observed in the peripheral hearing evaluation. The constellation of behavioral, cognitive, linguistic and perceptual symptoms described for Fragile X syndrome, in addition to the structural central nervous alterations observed in the Dandy-Walker variant, caused outstanding interferences in the development of communicative abilities, in reading and writing learning, and in the individual's social integration.

ABSTRACT

A síndrome de Dandy-Walker é uma malformação cerebral caracterizada por hipoplasia ou agenesia do vérmis cerebelar e dilatação do quarto ventrículo, com formação cística na fossa posterior. O diagnóstico é realizado, na maioria dos casos, no período prénatalou na primeira infância, decorrente de anormalidades no desenvolvimento fetal ou de sinais e/ou sintomas de hidrocefalia. Raros casos assintomáticos são descritos no adulto, quase sempre diagnosticados casualmente a partir de exames de imagem. O paciente descrito neste relato foi diagnosticado com a malformação de Dandy-Walker aos 16 anos de idade após apresentar crises epilépticas convulsivas generalizadas como possível manifestação clínica da doença.

ABSTRACT

La malformación de Dandy–Walker es una alteración congénita que compromete el cerebelo y el cuarto ventrículo. Esta condición se caracteriza por agenesia o hipoplasia del vermis cerebeloso, dilatación quística del cuarto ventrículo y alargamientode la fosa posterior. Aproximadamente, 70-90% de los pacientes presenta hidrocefalia, que se desarrolla, generalmente, en el periodo postnatal. La malformación de Dandy-Walker puede estar asociada con atresia del foramen de Magendie y, posiblemente, del foramen de Luschka. La malformación de Dandy-Walker fue descrita por primera vez por Dandy y Blackfan en 1914. Estudios realizados por D’Agostino en 1963 y Hart et al en 1972 definieron la triada característica de la malformación de Dandy-Walker que consiste en (1) agenesia parcial o completa del vermis; (2) dilatación quística del cuarto ventrículo y (3) alargamiento de la fosa posterior.Esta triada típica se encuentra, generalmente, relacionada con hidrocefalia supratentorial, que debe considerarse más como una complicación que como parte del complejo de la malformación. La incidencia de la malformación de Dandy-Walker es de 1 caso/25 000 – 35 000 nacidos vivos. La malformación de Dandy- Walker es la causa de aproximadamente 1-4% de los casos de hidrocefalia; las tasas de mortalidad por la malformación alcanzan entre un 12-50%; y, asociada con otras malformaciones congénitas, constituye el 83% de la mortalidad postnatal.La malformación de Dandy-Walker ocurre más frecuentemente en mujeres que en hombres; el diagnóstico se hace con ultrasonido, resonancia magnética y Tomografía axial computarizada. El tratamiento de esta patología está basado en el manejo de la hidrocefalia.


Dandy-Walker malformation is a rare congenital disease involving the cerebellum and the fourth ventricle. This condition is characterized by agenesia or hypoplasia of the cerebellar vermis, cystic dilatation of the fourth ventricle, and enlargement of the posterior fossa. Approximately 70-90% of patients have hydrocephalus, which often develops postnatally. Dandy-Walker malformation may also be associated to atresia of Magendie’s foramen and, possibly, Luschka’s foramen.Dandy-Walker malformation was described by Dandy and Blackfan in 1914. Then, studies by D’Agostino in 1963 and Hart et al in 1972 defined the characteristic triad of Dandy-Walker malformation as consisting of (1) complete or partial agenesis of thevermis, (2) cystic dilatation of the fourth ventricle and, (3) an enlarged posterior fossa. This triad is typically found in association with supratentorial hydrocephalus, which should be considered a complication rather than part of the malformation complex. The incidence of Dandy-Walker malformation is 1 case/25 000-35 000 live births. Dandy-Walker malformation accounts for approximately 1-4% of hydrocephalus cases. Overall mortality rates of 12-50%, associated congenital anomalies contributed to 83% of postnatal deaths. Dandy-Walker malformation occurs more frequently in females than in males. Dandy-Walkermalformation is best diagnosed with the help of ultrasound, magnetic resonance imaging, and computerized axial tomography. The treatment for this condition is based in the management of hydrocephalus.

ABSTRACT

Objetivos: relatar o caso de um paciente com variante de Dandy Walker, chamando atenção para a importância da suspeita, investigação e manejo das repercussões clínicas.Descrição do caso: é relatado o caso de um paciente do sexo masculino, com quadro clínico e radiológico típico da Variante de Dandy Walker. Durante o pré-natal, através de ecografia obstétrica com 23 semanas e 3 dias, apresentou alterações sugestivas de Síndrome de Dandy Walker. Ao nascimento apresentou exame físico com fenda palatina, criptorquidia à direita, hexodactilia em ambos os pés. Apresentava ainda ecocardiograma com forame oval patente e persistência do canal arterial. O diagnóstico foi estabelecido através da ressonância magnética realizada após o nascimento, que evidenciava hipoplasia do vermis cerebelar, alargamento da fossa posterior e leve dilatação ventricular. Conclusões: este artigo procura caracterizar a variante de Dandy Walker, que é uma malformação congênita do sistema nervoso central e é o tipo mais comum da Síndrome de Dandy Walker. Seu fenótipo é variável, devendo-se sempre pesquisar malformações tanto intra quanto extracranianas, visto que o risco de mortalidade pós-natal aumenta quando existe esta associação. O tratamento envolve equipe multidisciplinar e o prognóstico é reservado, variando conforme o fenótipo.


Aims: To report the case of a patient with Dandy Walker Variant, reinforcing the importance of suspicion, investigation, diagnosis, and management of clinical presentations.Case description: A case of a male patient with clinical and radiological presentation typical of this disease is reported. During prenatal assessment, obstetrical ultrasound by 23 weeks and 3 days showed changes suggestive of Dandy Walker syndrome. At birth, physical examination showed cleft palate, right cryptorchidism and hexodactilia on both feet. He had also an echocardiography with foramen ovale and patent ductus arteriosus. The diagnosis was confirmed by magnetic resonance imaging after birth, showing hypoplasia of cerebellar vermis, enlargement of the posterior fossa and mild ventricular dilatation.Conclusions: This article aimed to characterize the Dandy Walker Variant, which is a congenital malformation of the central nervous system and is the most common type of Dandy Walker Syndrome. Its phenotype is variable and we should always search for both intra and extracranial abnormalities, since the risk of postnatal mortality increases when there is such association, as presented in this case. The treatment involves a multidisciplinary approach. Prognosis is limited and varies according to the phenotype.
