Masses in and Around the Spine
摘要
The anatomical spaces in and around the spine encompass the paraspinal compartment, the vertebral compartment and the epidural compartment. Tumors in these compartments may easily spread via adipose corridors, direct contact or hematogenous pathways. Classifications such as the Weinstein-Boriani-Biagini, SINS, and ESCC or Bilsky score are used to grade these tumors. Imaging features of main tumoral and pseudotumoral masses are described and shown in this review. Detection of masses beyond the spine and even beyond the paraspinal space can be of utmost importance and examples are shown why radiologists should avoid tunnel view into the spinal canal.
