“…They will appear isointense to the cord on T1-WI, hyperintense signals relative to the normal spinal cord tissue on T2-WI (Figures 1 and 2) 4 . They will demonstrate intense enhancement characteristics after contrast administration which is the rule, sometimes homogeneous, but often also heterogeneous or rim-like (Figure 2) 1,4 . Sometimes dark caps are seen, especially on T2WI, rostral and caudal images of the tumor representing hemosiderin deposits.…”

This paper discusses spinal cord tumors including imaging characteristics with emphasis on magnetic resonance imaging and advances in treatment. This is a retrospective study of 20 cases patients with neoplasms arising from the spinal cord. All of our cases were explored by magnetic resonance imaging (1.5T) using T1-weighted imaging (Spin Echo), T2-weighted imaging (Spin Echo) and T1-weighted imaging with Gadolinium administration. Pain is the earliest symptom, characteristically occurring at night when the patient is supine. Ependymoma were observed in 11 cases. Astrocytoma was noted in five cases. Other uncommon tumors were identified in four cases: oligodendroglioma (n=1), epidermoid cyst (n=1), hemangioblastoma and metastasis (n=1). In MRI most tumors are isointense or slightly hypointense compared to the normal cord signal with homogenous or irregular enhancement. We describe the characteristic magnetic resonance findings and differential diagnosis of spinal cord tumors. Spinal cord lesions comprise approximately 2-4% of all central nervous system neoplasms. Magnetic resonance imaging plays a central role in the imaging of spinal cord neoplasms.

“…4 Lumbar imaging protocols usually include two-dimensional (2D) T1-weighted spin-echo (SE), T2-weighted fast spin-echo (FSE), and T2*-weighted gradient-echo (GE) sequences. [5][6][7] Short-tau inversion recovery (STIR) and fatsuppressed T2-weighted FSE images are occasionally acquired to obtain additional information in patients with sciatica not explicable by standard MRI fi ndings. [8][9][10][11] Furthermore, the usefulness of 2D and 3D balanced steadystate free precession (b-SSFP) sequences-also known as balanced free-fi eld echo (b-FFE) (Philips Medical Systems, Best, The Netherlands), true fast imaging with steady precession (FISP) (Siemens, Erlanger, Germany), and fast imaging employing steady-state acquisition (FIESTA) (GE Medical Systems, Carrollton, TX, USA)-has recently been proved helpful for imaging the spine.…”
