Lumbar Neural Foraminal Extradural Lipoma: Case Report, Literature Review

Abstract

Introduction Extradural lipoma is a rare condition of which few cases have been described in the literature, and a low percentage of these appear in the lumbar spine. The purpose of our presentation is to describe a new case of this entity, to deepen understanding of the clinical and imaging findings of this condition as well as its treatment. Materials and Methods Retrospective study of a clinical case that arrived for consultation presenting a clinical picture of long-term lumbar pain for 2 years. For 9 months there was bilateral lumbosciatic pain, intermittently more severe on the right side, S1 sensory deficit right side. Clinical evaluation, physical examination, and imaging studies were performed. Results The following were evaluated: history, clinical picture, age, gender, type of images requested and their results, treatment undertaken, and time of evolution of the symptoms. A literature review of this condition was made, comparing what has been published with our experience. Conclusion The lumbar extradural spinal lipoma is a rare benign tumor lesion that can produce backache and neurological compression. When the patient consults because of the appearance of neurological disorders secondary to compression phenomena, MRI is the test of choice for the evaluation of this pathology. Recovery from the symptoms occurs in most cases after surgical decompression.
