Tumoral calcinosis is a rare disorder characterized by tumor-like calcified masses commonly occurring in the periarticular regions of the extremities. Conversely, intradural tumoral calcinosis of the spine is extremely rare, with only two previously reported cases. To our knowledge, this is the first intradural case located in the foramen magnum region.
