ABSTRACT
La espina bífida, o mielodisplasia, es una anomalía de origen multifactorial congénita que se presenta con mayor frecuencia durante el desarrollo embrionario. Se produce por el cierre parcial de los pliegues neurales conjuntamente con una fusión defectuosa de los arcos vertebrales. Su clínica es variable e incluye una serie de manifestaciones como expresión del compromiso neurológico. El diagnóstico se basa en la presencia de las manifestaciones clínicas ayudado de estudios imagenológicos. La corrección quirúrgica del defecto es la conducta terapéutica que se preconiza como adecuada. Se presenta el caso de una paciente de 34 años de edad con mielomeningocele no corregido en edad infantil que se presenta con complicaciones infecciosas y secuelas neurológicas. Se administró esquema de antibioticoterapia con varios antibióticos de amplio espectro, y se decidió intervenir quirúrgicamente, con lo que se logró el cierre del orificio comunicante de la región espinal con el exterior. Además, se reconstruyó la zona aledaña al mielomeningocele para evitar posible sepsis del Sistema Nervioso Central. La paciente tuvo una evolución favorable y fue dada de alta hospitalaria a los 7 días posteriores a la intervención quirúrgica sin secuelas neurológicas(AU)
Spine bifida, or myelodysplasia, is a multifactorial congenital anomaly that occurs most frequently during embryonic development. It is produced by the partial closure of the neural folds together with a defective fusion of the vertebral arches. Its clinic is variable and includes a series of manifestations as an expression of neurological compromise. The diagnosis is based on the presence of clinical manifestations, aided by imaging studies. Surgical correction of the defect is the therapeutic conduct that is recommended as adequate. This report presents the case of a 34-year-old patient with uncorrected myelomeningocele in childhood who presented with infectious and neurological sequelae complications(AU)

Objective:To explore the diagnostic value of ultrasound in posterior fossa anomalies (PFA) at 11-13 + 6 gestational weeks by measuring brainstem (BS), brainstem-to-occipital bone (BSOB) diameter and BS/BSOB ratio. Methods:A total of 209 normal fetuses (control group) were randomly selected from Beijing Obstetrics and Gynecology Hospital, Capital Medical University, between March 2018 and November 2021. Reference ranges for BS, BSOB diameter and BS/BSOB ratio were obtained on the mid-sagittal view of the fetal profile and the relationship of three parameters and crown-rump length (CRL) was investigated. The intra- and inter-observer reliabilities were determined by intraclass correlation coefficient (ICC) in 30 normal fetuses. Fourteen fetuses diagnosed with PFA in the same period including 10 cases of cystic posterior fossa malformations (cPFM) and 4 cases of open spine bifida (OSB) were retrospectively selected to compare BS, BSOB diameter and the BS/BSOB ratio with control group.Results:BS and BSOB diameters were successfully obtained in all control fetuses (100%), and the intra- and inter-observer reliabilities for BS and BSOB diameters were good (ICC=0.877, 0.846 and 0.939, 0.895). In the control group, BS and BSOB diameter linearly correlated with CRL ( r=0.867, 0.794; all P<0.001), while the BS/BSOB ratio was 0.75 (0.71, 0.79). There were significant differences of BSOB diameter and BS/BSOB ratio between control group and PFA group (all P<0.05). Except for one isolated vermian hypoplasia (VH), the BSOB diameters in 9 (90%) cases of cPFM were above the 95th percentile of the calculated normal range and were below the 5th percentile in 4(100%) cases of OSB.Except for one isolated VH, the BS/BSOB ratio in 9 (90%) cases of cPFM was below the 5th percentile of the calculated normal range. The BS/BSOB ratio in 4 (100%) cases of OSB was above the 95th percentile of the calculated normal range. Conclusions:The measurements of BS and BSOB diameter are feasible with good repeatability. Abnormal BSOB diameter and BS/BSOB ratio are suggestive for PFA. The posterior fossa of isolated VH can be normal in the first trimester.
