A 58-year-old man presented with lumbar spinal stenosis due to epidural lipomatosis. He underwent transsacral canal plasty (TSCP), in a manner similar to epidural adhesiolysis, which can be performed under local anesthesia. His leg pain improved dramatically in the year after surgery. Furthermore, magnetic resonance images during this time show neural decompression by reduction of the amount of epidural fat.
TSCP was found not only to relieve pain but also to achieve neural decompression in this patient with spinal canal stenosis caused by lumbar epidural lipomatosis. This is the first report to demonstrate the usefulness of TSCP for spinal epidural lipomatosis.
一名58岁男性因硬膜外脂肪增多症出现腰椎管狭窄。他接受了经骶管成形术（TSCP），手术方式类似于硬膜外粘连松解术，可在局部麻醉下进行。术后一年，他的腿痛明显改善。此外，在此期间的磁共振成像显示，硬膜外脂肪量减少，神经得到减压。
在这名因腰椎硬膜外脂肪增多症导致椎管狭窄的患者中，发现经骶管成形术不仅能缓解疼痛，还能实现神经减压。这是首份证明经骶管成形术对脊髓硬膜外脂肪增多症有用性的报告。
