Occipital Meningoencephalocele case report and review of current literature

Encephalocele: A Case Series From Abuja, North Central Nigeria

An encephalocele is a congenital tube defect in which there is an extension of intracranial structures outside the normal confines of the skull. Its presentation at birth provokes a lot of anxiety amongst parents, guardians and care providers with regards to compatibility with life, surgical treatments and effects on developmental milestones and higher mental functions. This report is on our initial experience in the first six months following surgical treatment of four consecutive cases presenting in infancy. The aim of this case series is to report our initial experience of the management of encephaloceles using four consecutive cases that presented in infancy. A review of four infants who presented to our neurosurgery service was conducted including patterns of presentation, neuroimaging findings, scope of surgical intervention and neurological outcome at the six-month review. The results are presented in short case reports and summarized in a table. Two five-month-old females, one six-month-old female and one two-month-old female infants presented to our neurosurgery clinic with progressively increasing encephaloceles at different locations. Brain MRI revealed meningo-encephalocele in all, but with associated hydrocephalus in two cases only. They all had excision and repair of encephalocele under the same general anaesthesia while only two had a ventriculoperitoneal (VP) shunt. Developmental milestones were on course at 6 months follow-up following discharge. Although the presentation of encephaloceles can be frightening to parents and care providers, careful clinical and radiological evaluation is a recipe for sound surgical planning and improved outcome.

Giant occipital encephalocele: a case report, surgical and anesthetic challenge and review of literature

Background

An encephalocele is a congenital neural tube defect characterized by herniation of cranial contents through a defect in the cranium and is caused by failure of the closure of the cranial part of the developing neural tube. An encephalocele is termed as “giant encephalocele” when the size of encephalocele is larger than the size of the head. They depend on size of the sac, percentage of neural tissue content, hydrocephalus, infection, and other associated pathologies for a favorable neurological outcome.

Case presentation

We report a case of a four-month-old boy with a giant occipital encephalocele measuring 21 × 15 × 19 cm in size, which was a surgical and anesthetic challenge for us. Intubation was achieved in lateral position. Part of occipital and cerebellar parenchyma was present in the sac and bony defect was approximately 2.5 cm in occipital bone in midline. We performed surgical excision and repair with a good overall outcome.

Conclusion

Perioperative management of a giant occipital encephalocele is a challenge for both anesthesiologists and neurosurgeons. Managing such a case demands a search for other congenital abnormalities, expertise in handling airway, and proper intraoperative care. Careful planning and perioperative management are essential for a successful outcome.

Analgesia and sedation modalities used with botulinum toxin injections in children with cerebral palsy: a literature review

Cerebral palsy (CP) is a non-progressive motor dysfunction leading to multiple morbidities, including spasticity, which can be managed with botulinum toxin injection (BTI). This literature review aims to examine published studies on the efficacy and safety of different interventions used to reduce pain and anxiety associated with BTI in children with CP. A literature review of all published evidence in English language, or with an English translation between 1999 and 2019, using PubMed, EBSCO host, and Medline databases was carried out. All identified papers were screened for inclusion criteria. Data from included papers were entered and analyzed on an Excel database. Twenty-one studies conducted in multiple clinical settings identified 10 different analgesia and sedation modalities including intravenous ketamine, midazolam, inhaled nitrous oxide, general anesthesia, and Eutectic Mixture of Local Anesthetics (EMLA^®) cream. Most of the studies were descriptive with the exception of two clinical trials and one qualitative study. All interventions had some adverse effects, but they were generally mild and no long-term sequelae were reported. The combination of inhaled nitrous oxide with EMLA^® cream showed promising primary results. However, ketamine and midazolam combination could be a safe alternative. Currently, there is no sufficient data to draw on the superiority of any modality. Further high-quality studies are warranted.
