A thoracic extradural chordoid meningioma: a unique case report and literature review.

We describe the unique case of a patient being diagnosed with a thoracic extradural chordoid meningioma following her presentation with mild lower limb pyramidal weakness and a T8 sensory level. This is the first report of an extradural chordoid meningioma being identified in the thoracic spine. The tumour was successfully resected through a posterior thoracic laminectomy approach. Post-operatively, her neurological deficit resolved and to date she has not experienced a radiological recurrence. In this report, we review the literature and discuss this unusual tumour's characteristics and prognostic significance.
