| description | An unusual case of a thoracic spine lipoma presenting with profound progressive numbness along with difficult to interpret preoperative imaging is discussed. A uniquely minimally invasive surgical treatment approach with successful outcome and improved neurologic symptoms is presented. A literature review and discussion of the benefits and limitations of a minimally invasive surgical technique are provided. A male presented with several months of progressive bilateral lower extremity numbness that ascended to the mid-thoracic spine. Spine magnetic resonance imaging demonstrated a 9 mm intradural, thoracic spinal mass, which was thought preoperatively to represent an arachnoid cyst with an adhesion or a localized dural ectasia. Subsequent imaging demonstrated a band at the cranial margin of the mass appearing to tether the spinal cord to the dorsal-lateral spinal canal without an arachnoid cyst or osseous defect. Surgical exploration revealed an intradural exophytic, intramedullary fatty mass tethering the spinal cord to the dorsolateral dura. An abnormal patch of dura was observed overlying the fatty attachment but no dural defect was identified. Pathology demonstrated fragments of fibroconnective tissue, scattered mature adipocytes, and entrapped meningeal cells, yielding the diagnosis of a spinal cord lipoma. Follow up imaging demonstrated no residual tethering of the spinal cord. |
