■Dandy-Walker畸形或综合征是最常见的后颅窝畸形。它通常与其他先天性异常有关,如心脏缺陷;然而,与巨大的枕骨脑膜膨出的关联极为罕见,因为只描述了大约34例。
我们报告一例2个月大的女婴出现中线,脑后巨大的肿块。它最初是在产前超声检查中发现的。测量的质量约为15×5厘米,延伸到中后卫,不会因哭泣而改变大小,没有附着在后面,并进行了积极的透照试验。在做了脑部计算机断层扫描后,诊断得到了证实,这显示了疣的发育不全,后颅窝扩大,以及两个脑室的囊性扩张,并通过骨缺损突出。
■我们的病例强调了巨大的枕骨脑膜膨出与Dandy-Walker综合征之间的罕见关联,在医学文献中很少讨论或报道。通过报道这种极为罕见的Dandy-Walker综合征与巨大的枕骨脑膜膨出有关,我们希望有助于为未来的研究建立一个数据库,以便建立一个管理方案,供临床医生和神经外科医生使用,从而更好地管理病情.
UNASSIGNED: Dandy-Walker malformation or syndrome is the most common posterior fossa malformation. It is commonly associated with other congenital anomalies such as cardiac defects; however, association with a giant occipital meningocele is extremely rare, as only around 34 cases have been described.
UNASSIGNED: We report a
case of a 2-month-old female infant who presented with a midline, gigantic mass in the back of the head. It was first discovered on a prenatal ultrasound. The mass measured about 15 × 5 cm, extending to the midback, not changing in size with crying, not attached to the back, and with a positive transillumination test. The diagnosis was confirmed after doing a brain computed tomography, which revealed hypoplasia of the vermis with an enlarged posterior fossa as well as cystic dilation of both ventricles with herniation through a bone defect.
UNASSIGNED: Our
case highlights a rare association between giant occipital meningocele and Dandy-Walker syndrome that is rarely discussed or reported in the medical literature. By reporting this extremely rare
case of Dandy-Walker syndrome associated with a giant occipital meningocele, we hope to contribute to the creation of a database for future research so that a management protocol can be established for use by clinicians and neurosurgeons for better management of the condition.
