We present a case of a progressive symptomatic intramedullary cyst, diagnosed decades after Lipiodol injection. Lipiodol was originally administered intrathecally for the radiologic diagnosis of spinal masses. A link between the lesion and the history of Lipiodol injection was never suspected. ⋯ We hypothesize that the syrinx is secondary to the impact of cerebrospinal fluid pulsations on the reactive membrane and that this membrane originated from an arachnoiditis caused by Lipiodol deposits. Lipiodol was indeed abandoned after it was found to cause arachnoiditis and neurologic sequelae. Despite the cessation of its usage, the causal role of Lipiodol in arachnoiditis and spinal cyst formation should still be considered, as symptoms may arise many years after Lipiodol administration.

Review Meta Analysis Comparative Study
Determining the difference in clinical and radiological outcomes between expandable and non-expandable titanium cages in the cervical fusion procedures: A Systematic Review and Meta-Analysis.
Expandable cages have been increasingly used in cervical and lumbar reconstructions; however, there is a paucity in the literature on how they compare with traditional nonexpandable cages in the cervical spine. We present a systematic review and meta-analysis, comparing the clinical and radiologic outcomes of expandable versus nonexpandable corpectomy cage use in the cervical spine. ⋯ The use of expandable cages may carry a modest improvement in radiologic outcomes compared with nonexpandable cages in the cervical spine; however, they may also lead to a higher rate of revisions based on our analyses.
