Calcifying Pseudoneoplasm of the Neuraxis Arising From the Sacral Canal: Case Report and Review of the Literature.

Background: Calcifying pseudoneoplasm of the spine is an extremely rare lesion and has not yet been reported in the sacral canal.

Case Description: We present the first known case of a calcifying pseudoneoplasm of the neuraxis arising from the sacral canal and discuss the clinicopathological features and neuroradiological findings of this lesion.

Conclusions: Calcifying pseudoneoplasm of the neuraxis can occur throughout the spine, including the sacral canal, and should be included in the differential diagnosis of intraspinal calcified lesions.
