“…The locations are not randomly distributed over the neural tube ( P = 2.0*10 −5 ) but show a preference for the occipital region, vertebrae C6 till T3 and the region between T8 and S1 with a peak at L5.

Single‐site neural tube closure in human embryos revisited

Since the multi-site closure theory was first proposed in 1991 as explanation for the preferential localizations of neural tube defects, the closure of the neural tube has been debated. Although the multi-site closure theory is much cited in clinical literature, single-site closure is most apparent in literature concerning embryology. Inspired by Victor Hamburgers (1900-2001) statement that "our real teacher has been and still is the embryo, who is, incidentally, the only teacher who is always right", we decided to critically review both theories of neural tube closure. To verify the theories of closure, we studied serial histological sections of 10 mouse embryos between 8.5 and 9.5 days of gestation and 18 human embryos of the Carnegie collection between Carnegie stage 9 (19-21 days) and 13 (28-32 days). Neural tube closure was histologically defined by the neuroepithelial remodeling of the two adjoining neural fold tips in the midline. We did not observe multiple fusion sites in neither mouse nor human embryos. A meta-analysis of case reports on neural tube defects showed that defects can occur at any level of the neural axis. Our data indicate that the human neural tube fuses at a single site and, therefore, we propose to reinstate the single-site closure theory for neural tube closure. We showed that neural tube defects are not restricted to a specific location, thereby refuting the reasoning underlying the multi-site closure theory. Clin.

“…A recent literature review found 48 reported cases of multiple NTDs in the same patient in the past 50 years [12]. Among those cases, there were only 5 cases reported as double encephalocele [12][13][14][15][16], and 3 reported cases of both occipital encephalocele with suboccipital or cervicothoracic myelomeningocele [11,17]. Here, we report a case of both occipital encephalocele with cervical myelomeningocele, and discuss the multisite theory for neural tube closure.…”

“…The timing of NTD surgical repair is controversial [14]. However, early closure of the myelomeningocele provides a better prognosis for neurogenic bladder in children, and prevents CSF infection and further neurological deterioration [15,16]. The prognosis of surgically treated occipital encephalocele depends on the presence of brain tissue in the lesion.…”

Multiple Neural Tube Defects: A Case Report

2020

View full text Add to dashboard Cite

Congenital defects/diseases Background:Incomplete closure of the neural tube results in congenital anomalies called neural tube defects (NTD). These defects are rarely multiple, and are characterized by loss of central nervous system soft tissue and bony coverings, along with herniation of the involved part of the CNS through the defect. Case Report:A newborn female infant was delivered through planned cesarean section due to large occipital encephalocele diagnosed antenatally. The pregnancy was unplanned and the mother did not take folic acid prior to conception. Birth weight was 3.41 Kg. Upon delivery, the newborn was healthy, with an Apgar score of 8. The physical examination revealed 2 large pouches; one was over the occiput, and the other swelling was located over the nape of the neck. Brain MRI revealed large occipital encephalocele and cervical myelomeningocele. The 2 defects were repaired separately, with an uneventful postoperative course. Conclusions:We report the rare occurrence of multiple NTD. Early repair, either as single or multiple procedures, is mandatory to avoid dramatic complications.
