Brown Sequard Syndrome

We report the case of a 45-year-old female who presented with acute left abdominal pain and subsequently developed a left partial Brown-Séquard syndrome. Spinal fluid, inflammatory and prothrombotic tests were unremarkable. Magnetic resonance showed a left intraforaminal disc prolapse at the T9–T10 level and a hyperintense lesion on T2-weighted images in the left postero-lateral cord at the T8–T9 level with restricted diffusion on DWI imaging. A diagnosis of spinal cord infarction due to compromise of the left T8 thoracic radicular artery was made. The patient was managed conservatively and at the 3 months follow-up, she was ambulant and able to walk small distances without a walker.

Common Cause

Introduction: Acute spinal cord infarction represents 1% of all strokes. The neurological presentation of spinal cord infarction is defined by vascular territory i.e. anterior or posterior spinal arteries. A broad spectrum of diseases can cause spinal cord infarction, most common cause is surgical repair or diseases of the thoracoabdominal aorta. MRI of the spine shows hyperintensities on T2WI, restricted diffusion on DWI and vertebral body infarction adjacent to a cord signal abnormality. Poor prognostic factors for recovery are severe impairment at presentation, female sex, advanced age, and lack of improvement in the first 24 hours. We describe clinical presentation, radiological findings and 3-month outcome of four patients who presented with ischemic spinal cord infarction. Methods: We retrospectively analysed our prospectively collected data and found four cases of spinal cord infarction for the period of May 2020 to April 2021. Total of 1,326 stroke patients (1125 i.e. 85% ischemic and 201 i.e. 15% haemorrhagic) were admitted in Hamad General Hospital. At our centre, spinal cord infarction accounts 0.30% of total stroke and 0.35% of ischemic strokes. We describe four young patients, presented with abrupt onset of focal neurologic deficit. Their MRI of the spine revealed hyperintensity signals in T2WI, restricted diffusion on DWI of spinal cord. Two patients had vertebral artery occlusion or dissection. One patient was discharged home and three patients underwent multidisciplinary rehabilitation program. Discussion: Spinal cord infarction may present with acute paraparesis or quadriparesis with devastating consequences. Blood flow to the spinal cord is influenced by perfusion pressure. The most common cause of spinal cord infarction in this case series was vertebral artery dissection or occlusion. Our case series suggests early recognition of spinal cord stroke, appropriate investigations and early treatment with further rehabilitation could improve patient outcome. Conclusion: Spinal cord infarction, a rare but devastating condition, represents 1% of all strokes but 0.3% of total strokes at our centre. Early recognition of spinal cord ischemia especially when presenting with abrupt onset focal neurological deficit, focus on underlying pathology with appropriate imaging and further investigations, secondary stroke prevention and rehabilitation are vital factors to improve neurological recovery. Future randomized trails are needed to establish the efficacy and safety of drug therapy including rt-PA in spinal cord infarction.

Abstract OBJECTIVE: Intramedullary spinal cord arteriovenous malformations (AVMs) have an unfavorable natural history that characteristically involves myelopathy secondary to progressive ischemia and/or recurrent hemorrhage. Although some lesions can be managed successfully with embolization and surgery, AVM size, location, and angioarchitecture precludes treatment in many circumstances. Given the poor outlook for such patients, and building on the successful experience with radiosurgical ablation of cerebral AVMs, our group at Stanford University has used CyberKnife (Accuray, Inc., Sunnyvale, CA) stereotactic radiosurgery (SRS) to treat selected spinal cord AVMs since 1997. In this article, we retrospectively analyze our preliminary experience with this technique. METHODS: Fifteen patients with intramedullary spinal cord AVMs (nine cervical, three thoracic, and three conus medullaris) were treated by image-guided SRS between 1997 and 2005. SRS was delivered in two to five sessions with an average marginal dose of 20.5 Gy. The biologically effective dose used in individual patients was escalated gradually over the course of this study. Clinical and magnetic resonance imaging follow-up were carried out annually, and spinal angiography was repeated at 3 years. RESULTS: After a mean follow-up period of 27.9 months (range, 3–59 mo), six of the seven patients who were more than 3 years from SRS had significant reductions in AVM volumes on interim magnetic resonance imaging examinations. In four of the five patients who underwent postoperative spinal angiography, persistent AVM was confirmed, albeit reduced in size. One patient demonstrated complete angiographic obliteration of a conus medullaris AVM 26 months after radiosurgery. There was no evidence of further hemorrhage after CyberKnife treatment or neurological deterioration attributable to SRS. CONCLUSION: This description of CyberKnife radiosurgical ablation demonstrates its feasibility and apparent safety for selected intramedullary spinal cord AVMs. Additional experience is necessary to ascertain the optimal radiosurgical dose and ultimate efficacy of this technique.

We report a case of temporal lobe epilepsy and incomplete Brown-Sequard syndrome of the thoracic cord. Computed tomography and magnetic resonance (MR) imaging showed multiple supratentorial masses with the classical radiological appearances of multifocal dysembryoplastic neuroepithelial tumour (DNET). Spinal MR imaging revealed intradural lipomas, not previously reported in association with multifocal DNET. Presentation and imaging findings are discussed along with classification and natural history of the tumour.

T2 Hyperintensity

Spinal cord infarctions are rare. They are difficult to diagnose clinically and remain undiagnosed even after extensive investigations. Magnetic Resonance (MR) features include hyperintensity of the cord on T2W images. Few cases of spinal cord infarction associated with vertebral body infarction are reported in the literature. We describe another five cases of spinal cord infarction with histopathological confirmation of the vertebral body signal changes. MR examinations of five patients who presented with acute spontaneous spinal cord syndrome were reviewed. Abnormal MR features of the spinal cord included signal changes within the parenchyma, best demonstrated on T2W images. These cord changes were associated with vertebral body T2 hyperintensity in all the patients and in one patient, the computed tomography guided biopsy of vertebral body lesion reported infarction. MR is sensitive to detect spinal cord infarctions and associated vascular and bony changes. The associated signal abnormalities in the bone marrow are a corroborative sign in the diagnosis of spinal cord infarction which was proved by histopathology.

✓ Transient neuroimaging abnormalities associated with seizure activity have received little attention in the literature. The authors report a focal magnetic resonance (MR) imaging abnormality of the corpus callosum in a patient following a secondary generalized seizure. A 27-year-old right-handed man presented with a history of medically refractory partial seizures since the age of 1 year. The results of an MR imaging study obtained 4 months prior to the patient undergoing video-electroencephalography monitoring were unremarkable. After the patient discontinued all antiepileptic medications, a secondary generalized seizure of right temporal origin was recorded. Five days later, repeated MR imaging revealed a nonenhancing 14 × 11—mm ovoid hyperintense lesion in the splenium of corpus callosum. The patient was asymptomatic, and his neurological and neurocognitive examinations remained unremarkable. Follow-up MR imaging 5 weeks and 1 year later demonstrated near-complete resolution of the lesion. Benign and transient abnormalities in the splenium can occur as a periictal phenomenon. A high index of suspicion and follow-up imaging may prevent further unwarranted intervention.
