To determine the MR criteria that are effective for differentiating intramedullary neoplasms from syringo- or hydromyelia, we reviewed MR scans made on prototype and commercial imagers of 33 patients with surgically confirmed cord abnormalities, including nine intramedullary neoplasms and 20 cysts (syringo- or hydromyelia). Two radiologists who did not know the clinical and radiologic diagnoses...

Background: Metastasis of systemic neoplasms to the spine is common; however, metastasis primary spinal cord tumors other regions in body an infrequent occurrence. A few case reports have described tumors, and most cases, patients were younger than 30 years age. Case Description: We present illustrative a 47-year-old female with metastatic lesions lumbosacral vertebrae after initial diagnosis i...

A 23-year-old Brazilian man, a farmer in a rural area of Minas Gerais State, complained of an 8-month history of neck pain and upper-limb weakness. Flaccid tetraparesis, global hyperreflexia, and pyramidal signs were present. Cranial CT and brain MRI were normal. Spinal cord MRI showed an intramedullary tumoral lesion, extending from C3 to C5 vertebral bodies, with a cystic appearance (figure 1...

A previously healthy eighteen year old female presented with interscapular pain of 6 months duration. She also experienced progressive decline in her ability to perform fine motor skills such as handwriting as well as deficiency in coordination and motor strength. Imaging of the spine revealed a well demarcated intradural intramedullary lesion in the central portion of the cervical spinal cord....

and (3) paresis , loss of sensation, and low levels of protein in the CSF are more common. Unenhanced CT examinations can show an intramedullary mass with zones of low density suggestive of a cystic component; if the cord is collapsed , syringomyelia can reliably be assumed to be present. If the cord is not collapsed , which occurs more frequently, it is impossible to differentiate syringomyeli...

The aim of the present study was to investigate the risk factors for postoperative recurrence of spinal tumors by logistic regression analysis and analysis of prognostic factors. In total, 77 male and 48 female patients with spinal tumor were selected in our hospital from January, 2010 to December, 2015 and divided into the benign (n=76) and malignant groups (n=49). All the patients underwent m...

PURPOSE Our purpose was to describe the MR imaging features in a series of spinal intramedullary gangliogliomas and to compare these findings with the MR features of intramedullary astrocytomas and ependymomas. METHODS A retrospective analysis was performed of 76 MR examinations in 27 patients with histologically proved spinal ganglioglioma; these were then compared with imaging findings in a...

Introduction ▼ Primary spinal tumors are relatively rare lesions, representing 4–8 % of all central nervous system tumors (Duong LM et al. Cancer 2012; 118: 4220–4227). Magnetic resonance imaging (MRI) represents the gold standard for the diagnosis and assessment of intradural tumors. Nevertheless, sometimes MRI may not accurately differentiate between intramedullary and extramedullary tumors. ...

Pediatric intramedullary spinal cord astrocytomas are rare, and the majority are low grade, typically carrying a low risk of mortality, but a high risk of morbidity. Quality of life is, therefore, an important consideration in treating concomitant progressive kyphoscoliosis. Compared with fusion-based spinal stabilization, fusionless techniques may limit some complications related to early inst...
