Spinal cord compression due to multivel thoracic disc herniation: surgical decompression using a "combined" approach. A case report and review of the literature

A case presenting with signs of spinal cord compression due to double contiguous thoracic disc herniation (TDH) is reported. A 66-year-old woman presented with a 4-month history of intermittent episodes of weakness and numbness in the lower extremities, and urinary dysfunction. Six weeks prior to admission complete paraplegia developed. The diagnosis was established by MRI. Treatment consisted of complete excision of the herniated discs (T8-T9 and T9-T10) and decompression of the spinal cord with a right transpedicular approach combined with standard posterior approach. The postoperative course was uneventful, and the improvement was dramatic. We also include a review of other 39 case reports from the literature. This article highlights the importance of consideration of TDH when one deals with a case with an anterior mass causing spinal cord compression.
