Abstract text Aim: the aim of this educational poster is to illustrate the most frequent spinal tumors and their main differential diagnosis, pearls and pitfalls.

Methods: we have conducted a search in our PACS over the last ten years by using the following search terms: tumor, spondylodiscitis, astrocytoma, ependymoma, cavernoma, meningioma). We subsequently selected the most representative cases of spinal tumors and tumor mimics (MRI and CT). The MRI imaging protocols comprise both standard morphological sequences (T1WI, T2WI, STIR) and advanced techniques (DTI, tractography, perfusion). Lesions were classified according to anatomical location (intramedullary, intradural extramedullary, extradural).

Results: this poster illustrates different benign and malignant spinal tumors as well as the main differential diagnosis. The pathological entities shown are astrocytoma (OMS grade I and II), glioblastoma, ependymoma, myxopapillary ependymoma, hemangiomablastoma, cavernoma , meningioma, neurofibroma, schwannoma, metastasis, lymphoma, spondylodiscitis, lipoma of the filum terminale, arthro-synovial cyst, ventriculus terminalis, and discal hernia.
A section of the poster will be dedicated to showing artifacts on MRI that could mimic pathology.

Conclusion: MRI is the method of choice for the characterization of spinal tumors. Advanced techniques are invaluable tools in achieving a high degree of accuracy in presurgical planning and also to narrow the differential diagnosis of spinal lesions.
