Mayer-Rokitansky-Kuster-Hauser syndrome type II: A rare case.

Mayer-Rokitansky-Kuster-Hauser (MRKH) is a malformation complex comprising absent vagina and absent or rudimentary uterus. MRKH syndrome may be attributed to an initial affection of the intermediate mesoderm consequently leading (by the end of the 4th week of fetal life) to an alteration of the blastema of the cervicothoracicsomites and the pronephricducts. These latter subsequently induce the differentiation of the mesonephric and then the Wolffian and Mullerian ducts. There are very sparse such cases reported. We present a case of type II MRKH or Mullerian renal cervical somite association (i.e., Mullerian duct aplasia, renal dysplasia, and cervical somite anomalies).

Diagnóstico prenatal del Síndrome de Dandy-Walker clásico / Prenatal diagnosis of the classic Dandy-Walker's syndrome

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

A new association: Dandy-Walker's variant and tatralogy of Fallot with atrial septal defect and patent ductus arteriosus and primary hypothyroidy.

An 11-month-old girl who has Dandy-Walker's variant (DWV) associated with tetralogy of Fallot (TOF), atrial septal defect (ASD), patent ductus arteriosus (PDA), and primary hypothyroidy is presented. There has been no report describing a case of DWV associated with TOF, ASD and PDA and primary hypothyroidy. The first case of Dandy-Walker malformation associated with TOF was reported by Kohyama et al in 1988, since then, a few cases were reported in the literature. Our patient is the first reported case.
