Spinal metastatic lung adenocarcinoma with dural invasion and concomitant intradural and extradural components: a case report.

We report the case of a metastatic lung carcinoma that had metastasized to the thoracic extradural space and penetrated the dura, resulting in a combined extra and intradural spinal tumour. To our knowledge this is the first such report of a metastatic lung adenocarcinoma demonstrating direct dural invasion.
