“…A low intensity area on T2-weighted images in the acute stage is thought to indicate more extensive intramedullary hemorrhage and is attributed to deoxyhemoglobin (Figure 4a). 6,7,12,13 Its presence has been reported to suggest a poor prognosis for neurological recovery. 4,14,15 In our patients, nine of the ten patients exhibiting this low signal change had grade A paralysis from onset to 1 year after injury ( Figure 5: pattern 4).…”

In patients with acute traumatic cervical spinal cord injury, it is di cult to make a precise diagnosis of the main site of the injury, the severity of cord damage, and the prognosis of neurological complications Objective: To determine which images provide the most useful information and the best time to perform prognostic MRI. Design: The severity of neurological complications was assessed using the ASIA impairment scale. MRI was ®rst performed within 48 h of injury, and was subsequently performed after 2 ± 3 weeks, 3 months, 6 months, and 1 year. Setting: Inpatient SCI medicine unit. Subjects: Seventy-®ve patients with acute traumatic cervical spinal cord injury (9 women and 66 men) aged from 19 ± 89 years (mean: 54.7 years). Results: Four characteristic patterns of signal changes were observed on MRI. These patterns correlated well with the severity of spinal cord damage and the clinical outcome. Conclusion: T2-weighted images provided the most useful information, and the best times for prognostic imaging were at the time of injury and 2 ± 3 weeks later.

The evolution of intramedullary lesions following an acute spinal cord injury was monitored with sequential magnetic resonance (MR) imaging. Seven patients who had sustained cervical spinal cord injuries were followed up from the acute to the chronic phase of the cord injury. MR images were evaluated not only qualitatively but also quantitatively. All intramedullary lesions were quantita tively analysed by T2 values. In the qualitative analysis, the regions with hyperintensity on T2-weighted images and isointensity on T1-weighted images were consistent with the region of simple oedema or gliosis. The former gradually disappeared after the acute phase, whereas the latter remained until the chronic phase. The regions with hyperintensity on T2-weighted images and hypointensity on Tl-weighted images may represent cysts filled with necrotic tissue or clear fluid, or necrosis. The evolution of these lesions was also able to be monitored quantitatively by T2 values.

“…4 The usefulness of magnetic resonance (MR) imaging for the detection of spinal cord abnormalities is well described, especially in the acutely injured spine. 5,6 MR imaging can demonstrate several pathological features involving the spinal cord, including intraspinal hemorrhage, acute cord edema, and contusion of the spinal cord. 7 The appearance of intraspinal hemorrhage at MR image varies through several forms as the hematoma ages.…”

Brown–Séquard-plus syndrome due to stab injury: a case report

Study Design: Case report. Objective: To describe the mechanism of injury in this case and its clinical features. Magnetic resonance (MR) images of hemorrhage in spinal cord injury due to stab wound are discussed. Methods: We describe the case of a 21-year-old woman who was stabbed in the right side of her neck and developed left-sided Brown-Se´quard syndrome plus loss of bilateral proprioceptive sensation. Neither plain radiographs nor computed tomography of the cervical spine demonstrated any foreign bodies or fractures of the cervical spine. T2-weighted cervical MR images confirm spinal cord hemiresection at C5-C6. Results: MR imaging was performed serially at 4 days, 4 weeks, and 8 weeks after trauma. The signal pattern of the spinal cord at the site of injury varied iso, iso, and low on T1-weighted consecutive images. Meanwhile, high signal intensity on T2-weighted images was consistent during the 8 weeks after incidence of trauma. A T2-weighted sagittal image showed a tiny spot of low intensity in the high signal band at the site of penetration, demonstrating hemosiderin formation in the spinal cord. The patient was treated conservatively and, recovered from Frankel grade C to grade D. Conclusion: Spinal cord injuries (SCI) following stab wounds are rare. MR imaging is definitely useful for recording and monitoring the pathology of SCI.
