Calcifying pseudoneoplasm of the neuraxis: A case report and review of the literature

Calcifying pseudoneoplasms of the neuroaxis (CAPNON) are rare, slow-growing, fibro-osseous lesions that can occur throughout the entire neuroaxis with few reported cases. We describe a case of craniocervical CAPNON that was treated by our unit and review the available literature. CAPNON are rare benign lesions occurring throughout the neuroaxis. Although rare, these lesions should be considered in cases of histopathological and radiology features of calcified lesions in both brain and spine. Despite a paucity of reports complete safe surgical resection should remain the goal to obtain the best clinical outcomes. (C) 2019 Published by Elsevier Ltd.
