Abstract
Calcified thoracic disc sequestration is a very rare disease. Unusual sequestered
disc fragments mimic spinal tumors and other space-occupying lesions due to a lack
of discernible clinical features that can be used to differentiate these disc fragments
from disc herniations and tumoral lesions. In this report, we describe a patient with
a dorsally sequestrated calcified disc fragment in the thoracic spine that mimicked
a bony tumoral lesion of the spinal canal and present a literature review. Thoracic
disc sequestration accompanied by an atypical location requires a systematic diagnostic
approach involving accurate preoperative history and careful radiographic evaluation.
