This is a letter to share the clinical experience we had with neonates born with a specific feature of spina bifida. The lesion is like a meningocele containing skim amount of fluid, with a tiny dimple around the center of the cutaneous lesion which causes inward retraction of the dysplastic coverage. This feature is in favor of accompanied split cord malformation (SCM) type I, and the central nidus is in continuous with the dural sleeve around the bony septum of SCM. By recognition of this clinical clue, surgical repair can be planned to perform with appropriate provision, particularly foreseeing the amount of intraoperative bleeding and duration of anesthesia in the newborn patients.

One woman (aged 20) and two men (aged 57 and 29, respectively) presented with various urinary and abdominal symptoms, all of which were found at operation to have been caused by anterior sacral meningoceles. All three recovered uneventfully, though the woman was left with some residual numbness of the thigh. Anterior sacral meningocele is a rare condition in which a dural sac herniates into the pelvic region through a congenital defect in the sacrum. Since 1837 182 cases have been reported, and most of them presented with gastroenterological or urogenital signs and symptoms. We have reviewed their symptomatology, pathogenesis and treatment.

Lateral meningocele syndrome (LMS) is a rare genetic connective tissue disorder. It is associated with morphological changes similar to those of other connective tissue disorders, with the unique distinction of multiple, often bilateral and large, lateral meningoceles herniating through the spinal foramina. In some cases, these lateral meningoceles can cause pain and discomfort due to their presence within retroperitoneal tissues or cause direct compression of the spinal nerve root exiting the foramen; in some cases compression may also involve motor weakness. The presence of lateral meningoceles imposes unique challenges related to CSF flow dynamics, especially with concurrent Chiari malformation, which also occurs with increased frequency in individuals with LMS. The authors present the case of a 6-month-old female with LMS with multiple lateral meningoceles throughout the thoracic and lumbar spine. The infant experienced a focal neurological abnormality due to enlargement of her lateral meningoceles following decompression of a symptomatic Chiari malformation and endoscopic third ventriculostomy. The finding was reversed through implantation of a ventriculoperitoneal shunt, which reduced the burden of CSF upon the lateral meningoceles. Such a case compels consideration that CSF flow dynamics in addition to altered connective tissue play a role in the presence of lateral meningoceles in patients within this and similar patient populations.

A fetal MRI study obtained at 21 weeks' gestation revealed a suboccipital meningocele without hydrocephalus. One day after term birth, MRI demonstrated an acquired cerebellar encephalocele, and MRI obtained 5 months later showed progressive enlargement of the encephalocele, still without obvious hydrocephalus. The patient underwent an operation in which an external ventricular drain was placed, the grossly normal cerebellum was reduced into the posterior fossa without resection, and the dural defect was closed. The drain was weaned out over 5 days, and no ventriculoperitoneal shunt was placed. Postoperative MR images revealed normal cerebellum and no hydrocephalus. The patient is developmentally normal. Meningocele and encephalocele are embryologically distinct. An acquired encephalocele could develop from hydrocephalus (which was not present in this case), or secondary to the lower resistance to expansion into the dural defect of the meningocele relative to the resistance to expansion of the fetal skull. The cerebellar tissue was normal in this case, and was thus preserved. The developmental prognosis is excellent. To the authors' knowledge, this is the first reported case of this occurrence. It is important to differentiate between congenital and acquired encephalocele etiologies, because resection of the cerebellar tissue in an acquired encephalocele (as is routinely done in cases of congenital encephalocele) would be expected to result in neurological deficits.

INTRODUCTION
The possibility of an association between Dandy-Walker malformation and occipital meningocele is well-known. However, just an overall number of about 40 cases have been previously reported. Giant occipital meningocele has been described only in three newborns. Incidence, pathology, clinical presentation, and proper management of this association are still poorly defined.
REPORT OF THE CASE
An 8-year-old boy with Dandy-Walker malformation and giant (25 cm in diameter) occipital meningocele is presented. This boy was born without any apparent occipital mass and harbored no other significant malformations including hydrocephalus. On admission, he was neurologically intact and the giant occipital mass presented partially calcified cyst walls. Treatment consisted of the excision of the occipital malformation, cranioplasty, and cysto-peritoneal shunt. Outcome was excellent.
CONCLUSIONS
To the best of our knowledge, among the few reported patients with Dandy-Walker malformation associated to occipital meningocele, this is the oldest one and the one with the largest occipital meningocele; he is unique with calcified walls of the occipital meningocele and the only one who survived the repair of the giant malformation. In Dandy-Walker malformation, occipital meningocele may develop and grow regardless of hydrocephalus. Giant size may be reached and the cyst may become calcified. Surgical repair may warrant favorable outcome.

OBJECTIVE
To present a case of spontaneous cerebrospinal fluid (CSF) otorrhea from a fallopian canal meningocele involving the geniculate fossa and review all cases of fallopian canal CSF leak reported in the literature with discussion of management and outcomes.
METHODS
A 53-year-old woman with history of morbid obesity and hypertension presented to a tertiary care referral center with unilateral high-volume CSF otorrhea. High-resolution temporal bone computed tomography demonstrated significant dilatation of the geniculate fossa. Rates of postoperative facial paralysis and refractory CSF leak were reported for the present case and prior cases reported in the literature.
RESULTS
Locations of fallopian canal dehiscence, surgical approaches, techniques for packing dehiscence, rates of postoperative facial paralysis and CSF leak, and revision procedures were reported for the present case and 14 cases in the literature. The present case involved dehiscence of the geniculate fossa that was approached via combined transmastoid-middle cranial fossa exploration with facial nerve monitoring. The area of dehiscence was carefully packed with temporalis fascia, muscle, and artificial dural substitute overlay to repair the CSF leak without injuring the facial nerve. Postoperatively, no facial weakness was noted; however, right-sided high-volume CSF otorrhea persisted. After discussing treatment options, the patient underwent subtotal petrosectomy and blind-sac closure of the external auditory canal the following day. This successfully resolved the CSF leak without causing facial nerve weakness.
CONCLUSIONS
Fallopian canal meningocele is an exceedingly rare cause of CSF otorrhea. Successful repair requires precise packing of the dilated facial canal to occlude the leak without injuring the facial nerve. For refractory CSF leak, subtotal petrosectomy and closure of the external auditory canal warrants consideration.
