  • Title: Intradural-Extramedullary Cervical Cord Lipoma: Case Report and Literature Review.
    Author: Panagopoulos D, Markogiannakis G, Koutzoglou M.
    Journal: World Neurosurg; 2018 Feb; 110():162-168. PubMed ID: 29155065.
    Abstract:
    BACKGROUND: Spinal lipomas are generally thought to occur as a result of failed primary neurulation. Failed primary neurulation allows invasion of mesenchymal tissue of mesodermic origin into the neural structure, leading to the formation of a spinal lipoma. Despite most spinal lipomas being regarded as the result of failed primary neurulation, some confusion in terms of the embryogenesis of spinal lipomas remains. Recently, a novel classification of spinal lipomas based on embryonic changes seen during primary and secondary neurulation was has been proposed. CASE DESCRIPTION: We present a case of an intradural-extramedullary spinal cord lipoma, associated with a subjacent subcutaneous lipoma at the cervicothoracic region. The patient presented with worsening neurologic symptoms, indicating ongoing cervical myelopathy. A subtotal resection along with posterior cervical stabilization was achieved, with mild improvement of neurologic symptoms. Clinical, pathologic, and radiologic records are reviewed. CONCLUSIONS: To the best of our knowledge, this is the first described case of a spinal cord lipoma with at such a location, one that cannot be fully categorized within the newly proposed classification system.
