“…As spinal lipoma is an intramedullary tumor, total removal may injure the spinal cord leading to impairment of spinal function [26]. Clinical symptoms induced by spinal lipoma usually resulted from cord compression within the spinal canal rather than direct cord invasion by the tumor and due to secondary tethering of the spinal cord [20]. Yamada et al [31] defined the TCS as a stretch-induced functional disorder of the spinal cord with its caudal part anchored by an inelastic structure.…”

The authors present an unusual case of an intradural lipoma at the thoracolumbar level causing lateral tethering of the spine, with complicated scoliosis. A 6-year-old girl was admitted with progressive change in posture detected by her parents. Thoracolumbar scoliosis was detected by physical examination and X-ray studies. Spinal magnetic resonance imaging revealed an intradural lipoma and right lateral tethering of the spine at the upper lumbar level. After surgical release of lateral tethering and resection of the lipoma, fusion was performed by the orthopedic surgery team. Radiological and intraoperative findings of this extremely rare case are discussed.

“…In open spinal dysraphism, Diastematomyelia occurred most commonly in the dorsolumbar region followed by lumbar and lumbosacral regions. [2][3][4] In occult SD diastematomyelia occurred equally in dorsolumbar and lumbar regions (Table 8 and 9). (Figure 2 and 3).…”

“…1 Spinal dysraphism are mainly divided into open spinal dysraphisms in which there is exposure of neural elements to exterior through a defect in skin and closed spinal dysraphisms in which there is skin coverage to underlying spinal malformation. [2][3][4][5][6][7][8][9] This study depicting the various imaging features of Spinal dysraphism and the importance of Helical CT and MRI in the evaluation of Spinal dysraphism. Aim of the study was to assess the role of Helical CT and MRI in the identification of various forms of spinal dysraphism, characterization of the lesions and associated anomalies, giving a composite diagnosis based on specific Imaging findings.…”

Background: Spinal dysraphism is a complex congenital anomaly involving the spine and spinal cord. Some lesions seldom require imaging. The aim was to study the usefulness of helical CT and MRI in the evaluation of various presentation of spinal dysraphism, to identify, characterize the lesions and its association with other anomalies which helps in giving an accurate diagnosis based on specific imaging findings.Methods: Seventy patients including 33 males and 37 females’ age ranging from 1year to 30 years clinically suspicious for spinal dysraphism were evaluated using helical CT and MRI in the Department of Radiodiagnosis, Government Kilpauk Medical College and Hospital, Chennai, India.Results: Statistical data analyzed based on imaging findings.56 patients were of open spinal dysraphism type and 14 patients were of occult spinal dysraphism. Different imaging features in spinal dysraphism were evaluated to give composite diagnosis for management.Conclusions: Helical CT and MRI are adjuvant in evaluating cases of spinal dysraphism. MRI is excellent in characterizing the soft tissue spinal anomalies of spinal dysraphism helical CT is an excellent imaging modality for characterization of vertebral bony anomalies.

Background: The neural tube defects (NTDs) are a heterogeneous group of structural birth defects that arise from a complex array of multiple genetic and environmental factors and adversely affect the structure and function of the brain and spinal cord. Spinal NTDs are clinically more common than cranial NTDs. There remains a significant gap in linking the multiple NTD phenotypes to current genomic understanding. Methods: This article summarizes the neurosurgical clinical approach to spinal NTDs by correlating each step of embryonic development of the human nervous system with key management concepts for defects that arise at that step. Results: The NTDs are broadly classified as open or closed. Open defects include myelomeningocele (MMC), encephalocele, and anencephaly. Closed defects are also known as occult spinal dysraphism and are characterized by intact skin over the spinal defect. They are more common and often cause neurologic decline from tethered cord syndrome. Failure of primary neurulation gives rise to open myelomeningocele (MMC). Surgical closure of an open MMC focuses on realigning the tissue layers that failed to separate during neurulation. In utero closure is a promising recent technique. Chronic neurosurgical management largely focuses treating hydrocephalus. The Chiari II malformation is uniformly present in MMC patients and may cause brainstem dysfunction. Tethered spinal cord may progressively impair normal neurologic function but typically responds well to surgical untethering. Conclusions: Surgical closure of MMC centers on approximated realignment of embryologically disordered neural tissue. Clinical surgical management decisions in the spinal NTDs remains challenging but standardized principles have emerged.
