【 摘 要 】

Introduction

Spinal angiolipoma is a benign uncommon neoplasm composed of mature lipocytes admixed with abnormal blood vessels. They account for only 0.04% to 1.2% of all spinal tumors. We present a case of thoracic epidural angiolipoma treated by combining radical resection with instrumented spinal fixation, without any surgical complication.

Case presentation

A 32-year-old Asian woman presented with dorsal epidural angiolipoma at the upper-thoracic level. She had a seven-month history of gradually worsening weakness and numbness in her lower extremities. Imaging studies of her thoracic spine demonstrated a heterogeneously well-enhancing mass, located in her posterior epidural space without surrounding bone erosion at the upper thoracic level. We also observed compression of her thoracic cord. During surgery, a reddish-gray, highly vascularized mass was excised. Her facet joints had to be resected to expose the part migrating into the intervertebral foramen. Because there was concern regarding the stability of her thoracic spine, we performed spinal fixation using pedicle screws. Histopathological study of the surgical specimen showed a typical angiolipoma.

Conclusion

Angiolipomas can be radically excised with good prognosis. Surgical removal is the preferred treatment for spinal angiolipoma, and the prognosis after surgical management is very good. Although outcomes remained favorable despite incomplete resections in a number of spinal angiolipoma, complete removal is preferred. We successfully achieved total resection without any surgical complication by combining radical resection with instrumented spinal fixation.
