Cervical Myelocystocele: A One-in-50,000 Congenital Abnormality of the Spinal Cord

Neural tube defects are a group of birth defects that affect the development of the spinal cord and brain. Myelomeningocele is a type of neural tube defect that results in the protrusion of the spinal cord and meninges through a defect in the vertebral column. While myelomeningocele is a relatively rare condition, cervical myelomeningocele is extremely uncommon. The condition can lead to various neurological problems and atrophies and is typically diagnosed in the first trimester of pregnancy using an ultrasound examination. Surgical intervention is typically recommended to repair the affected vertebral column. In this report, we describe the case of a four-month-old baby boy who was diagnosed with a cervical myelocystocele and successfully treated surgically. The patient had an excellent postoperative status, and this case highlights the importance of early diagnosis and intervention in the management of this rare condition.

Case Report of an Anterior Thoracic Myelomeningocele: A Multidisciplinary Approach to Surgical Management

BACKGROUND

Cervicothoracic myelomeningocele (MMC) is a rare entity with only 2 reported cases in the literature of anterior thoracic MMC.

CASE DESCRIPTION

We report a third case in a 3-year-old boy. MMC was diagnosed during antenatal screening and later warranted surgical intervention. Despite being asymptomatic, radiologic surveillance demonstrated worsening syringomyelia, tonsillar descent, and cord signal change concerning for myelomalacia. Preoperative management involved respiratory assessment for pulmonary compromise, general pediatric consultation, gait analysis by physiotherapy, and serial imaging by radiology. Surgical management involved an anterior thoracotomy approach by cardiothoracic surgeons, repair of the MMC by neurosurgeons, and bone graft to ameliorate the bony defect in the vertebral body by orthopaedic surgeons. Postoperative care involved 4 days in the intensive care unit and 14 days on the pediatric neurosurgical ward. At 3-year follow-up, there was radiologic improvement of syringomyelia, tonsillar descent, and kyphoscoliosis with no neurological or pulmonary complications.

CONCLUSIONS

This case highlights the unique multidisciplinary surgical management of the rare entity of anterior thoracic MMC without scoliosis correction for radiologic progression.

Congenital Spinal Lipomatous Malformations. Part 1. Spinal Lipomas, Lipomyeloceles, and Lipomyelomeningoceles

Background: Lumbosacral spinal lipomas and lipomyeloceles are usually identified in early childhood. Terminology, histopathology, and diagnosis for these malformations can be confusing. Materials and Methods: This is a PubMed review with comparison of embryology, gross, and histopathology, and reporting requisites for these and related closed spinal malformations. Results: The spinal lipoma group (congenital spinal lipomatous malformations) includes subcutaneous, transdural, intradural, and noncontiguous malformations stretching through the entire lower spinal region. This lipomyelocele trajectory overlaps the embryonic tail's caudal eminence. Histopathologically, the lipomyelocele spectrum is a heterogeneous, stereotypical set of findings encountered from dermis to spinal cord. Diagnosis requires detailed correlation of images, intraoperative inspection, and histopathology. Conclusions: Appropriate terminology and clinicopathologic correlation to arrive at a diagnosis is a critical activity shared by pathologist and clinician. Prognostic and management differences depend on specific diagnoses. Familial and genetic influences play little if any role in patient management in closed spinal malformations.
