“…3 As such, most articles regarding the MR imaging findings of intramedullary astrocytomas were limited with respect to the number of patients; therefore, the frequency of nonenhancing astrocytomas varied from 0% to 50%. [7][8][9][10][11][12][13] However, the largest scale study showed that nonenhancing intramedullary astrocytomas were present in 29% of 35 patients with spinal cord tumors, 7 similar to those in the present study.…”

“…2 5 The differentiation between the spinal nerve root sheath and scars is more reliable in Gd enhanced than in un enhanced MR images. 26 On the basis of our present experience with the application of gadolinium com pounds in spinal cord injuries, we think that in order to obtain the maximal benefit from enhancement patients should be very care fully selected. We do not apply gadolinium systemically, but prefer first to consider the use of appropriate pulse sequences and suppression techniques.…”

Magnetic resonance (MR) images of 87 patients who had sustained spinal cord injuries during the past 2 years, were analyzed and compared with the corresponding clinical, surgical, and in some cases pathological findings. In addition to the standard MR imaging techniques applied in the spinal cord injuries, we also introduced some recent MRI technical achievements which are anticipated to improve diagnostic accuracy and broaden clinical application of this modality with regard to the spinal cord trauma. The recent technical advancements that we used include image enhancement, fat tissue signal suppression, three-dimensional (3-D) imaging, and magnetic resonance angio graphy (MRA). The reviewed post traumatic changes disclosed in these MR images were classified in 4 categories: acute, subacute, chronic, and the injury's sequelae. The essential properties of the 4 new imaging advancements are considered in relationship to the gain in diagnostic improvement of MRI of the 4 phases of patients with spinal cord trauma.

“…Of the 169 spinal cord ependymomas included in the Mayo series, 44% were located in the filum terminale; the remainder were termed intramedullary. 9 In the cervical and thoracic cord, they were seen as cord expansion in sagittal and axial planes, whereas at the cauda equina, they appeared as bulky intradural masses.…”

INTRODUCTIONTumors of the spinal cord or canal constitute approximately 15% to 20% of central nervous system tumors. Primary spinal tumors occur primarily in young1middle aged adults and are less frequently encountered in children and elderly. The sex incidence is roughly equal, although there is a definite, female predilection for Meningiomas. In general spine tumors are most frequently found in the thoracic spine. This is largely explained by the longer length of the thoracic spine relative to the remaining spine. Metastatic involvement of the spine is seen primarily in patients between the ages 50 and 70 years. The differential diagnosis of spinal neoplasms is primarily based on location of the lesion relative to the spinal cord and the ABSTRACT Background: Tumors of the spinal cord or canal constitute approximately 15% to 20% of central nervous system tumors. The differential diagnosis of spinal neoplasms is primarily based on location of the lesion relative to the spinal cord and the age, sex and clinical presentation. The aim and objective of the study was to determine the sensitivity of magnetic resonance imaging (MRI) in diagnosing intra spinal tumors and to correlate findings on MRI with histopathological diagnosis. Methods: This is a retrospective study. The study group included all the patients who presented to our hospital with progressive sensory or motor deficits, para or quadriperesis with or without bladder/bowel Involvement. Only patients with Intra dural lesions such as intradural extra medullary and Intra medullary lesions were included in the study. All the extra dural lesion cases such as vertebral tumors, degenerative/osteoporotic compressions and Trauma related cord compressions were excluded from the study. Results: Of the forty intradural tumors, 28 were extramedullary and 12 were intramedullary. Most of the tumors were located in the cervical and the dorsolumbar spine accounting for more than 50%. The most common tumor encountered in our study was schwannoma (22/40), followed by ependymoma (7/40), meningioma (4/40), astrocytoma (4/40), one each of Hemangioblastoma, Neuroentericcyst and Dermoid cyst. Ependymomas, Astrocytomas and hemangioblastoma were intramedullary lesions and the remaining lesions constituted Intra Dural extra medullary lesions. Conclusions: MRI was found to be a highly sensitive imaging procedure and the method of choice for intradural tumor evaluation and to differentiate extra medullary from Intra medullary lesions. It is not sensitive enough to differentiate the Intra medullary tumors. Nevertheless, definite diagnosis could be made by histopathology only.
