A Case of Large Cervical Intradural Lipoma with Externsion into the Posterior Fossa

ABSTRACT

Intraspinal lipomas are rare, benign neoplasms, comprising less than 1% of all intradural spinal tumors. Such tumors occur in the thoracic and cervical region, however, extension into the posterior fossa is most unusual. A case of large cervical intradural spinal liplma with extension into the posterior fossa in adult female is presented. Clinical feature was slowly progressing quadriparesis. Brain and cervical spine computed tomography confirmed the diagnosis and Magnetic resonance imaging was very useful for delineation of the anatomy of the lipoma as an aid in planning the operation. Operative therapy consisted of combined suboccipital craniectomy, spinal laminotomy and laminoplasty, subtotal tumor decompression.
