Spontaneous intramedullary hematoma in a patient with COVID-19 infection: A case report

SARS-CoV-2 and spinal cord ischemia: a systematic review on clinical presentations, diagnosis, treatment, and outcomes

BACKGROUND CONTEXT

Spinal cord ischemia is a rare but ominous clinical situation with high levels of disability. There are emerging reports on COVID-19 and spinal cord ischemic events.

PURPOSE

To investigate the cardinal manifestations of SARS-CoV-2 associated spinal cord ischemia, review treatment paradigms, and follow outcomes.

STUDY DESIGN

A systematic review.

METHODS

The current study was conducted under Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. The authors searched PubMed, Scopus, Web of Science, and Google Scholar for studies published up to February 12, 2023, on spinal cord ischemia and SARS-CoV-2 infection. Data on patient demographics, study methods, medical records, interventions, and outcomes were extracted from eligible articles. For each data set, the authors performed pooled estimates examining 3 factors of interest, which were (1) predisposing factors (2) treatment regimens, and (3) neurological rehabilitation outcomes. Neurological status was reported as the American Spinal Injury Association (ASIA) impairment scale reported by data sets.

RESULTS

Six data sets were identified. The mean age of the study population was 50 years old, with 66.6% male predominance. Sixty-six percent of the patients had severe COVID-19. Five data sets reported preexisting coagulopathy. ASIA A and B were the most prevalent primary neurological status (80%). The mean interval between COVID-19 and the first neurological deficit was 13 days. Anterior spinal artery lesions were the most prevalent ischemic pattern. The most common treatment regimens were heparin and steroid therapy. Physical rehabilitation showed poor functional outcomes.

CONCLUSIONS

SARS-CoV-2 is associated with spinal cord ischemia through multiple neuropathological mechanisms. Proper coagulation profile control and aggressive rehabilitation may play a promising role in the prevention and recovery of spinal cord infarction in SARS-CoV-2 patients.

Treatment refractory acute necrotizing myelitis after COVID-19 vaccine injection: a case report

Introduction and importance

Post-vaccination myelitis is a rare and debilitating clinical situation. There are few reports of post-COVID-19 infection and vaccination neurological sequela.

Case presentation

A 69-year-old lady was admitted to the emergency department due to weakness and hypoesthesia in her hands 1 week after the Sinopharm vaccine injection. MRI showed a cervicothoracic cord haemorrhagic lesion that deteriorated within 48 h. The clinical course was refractory to conservative treatments. She underwent an emergency cervical laminectomy as a salvage treatment. Intraoperative samples were in favour of acute necrotizing myelitis.

Discussion

In the review of the literature, the inflammatory storm, vasculitis, and many unknown etiologies are deemed to be the possible causes of encephalopathy and myelitis after COVID-19 infection and vaccination. There are few cases of post-COVID-19 myelitis and hematomyelia, but this case was the first report of post-vaccination necrotizing myelitis.

Conclusion

Post-vaccination necrotizing myelitis is a lethal medical situation requiring intensive and emergent neurosurgical vigilance. Early clinical diagnosis in the beginning and full neurosurgical-neurological treatment armamentarium options are cornerstones of treatment paradigms. Salvage treatment options such as extensive laminectomy may play a life-saving role in treatment refractory cases of acute necrotizing myelitis.

Spontaneous spinal epidural haematoma following COVID-19 vaccination: a case report

Introduction

COVID-19 vaccination side effects are rare but important medical situations. Spine-affecting side effects are amongst the rarest, but exceedingly important. Haemorrhagic spinal manifestations of COVID-19 and its vaccines are less reported with little knowledge about them.

Case presentation

An 80-year-old male who received his first shot of the COVID-19 vaccine had developed COVID-19 pneumonia, weakness, and sensory problems in his legs followed by sphincter incontinence within 5 days period. MRI showed a spontaneous epidural spinal epidural haematoma (SSEDH) in T10-L1. He underwent laminectomy and haematoma evacuation. One month follow-up showed no clinical improvement.

Discussion

To our knowledge, this was the first post-vaccination SSEDH and second in haemorrhagic spinal complications following COVID-19 vaccination. Considering the neuropathogenesis pathway of COVID-19 and its vaccines, there are common mechanisms of action that could potentially justify post-vaccination SSEDH such as seen in COVID-19 infection, itself. Early Neurosurgical intervention and better preoperative neurological status could be a beneficial modifier for favourable clinical outcomes.

Conclusion

SSEDH and COVID-19 vaccine coincidence is a rare clinical event, still no solid association could be scientifically explained. Further studies are required for a reliable pathophysiologic association. Early diagnosis, interdisciplinary medical approach, and faster intervention are the cornerstone of the treatment paradigm.

SARS-CoV-2 infection and spontaneous spinal hemorrhage: a systematic review

The neurological manifestations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, including spontaneous spinal hemorrhage (SSH), are diverse. SSH is a detrimental neurosurgical event requiring immediate medical attention. We aimed to investigate the association between SARS-CoV-2 and SSH and delineate a rational clinical approach. The authors searched PubMed, Scopus, Web of Science, and Google Scholar for studies published up to January 25, 2023, on SSH and SARS-CoV-2 infection. For each dataset, the authors performed pooled estimates examining three outcomes of interest: (1) early post-intervention neurological status, (2) mortality, and (3) post-intervention neurological rehabilitation outcomes. After reviewing 1341 results, seven datasets were identified for the final analysis. Fifty-seven percent of patients were females. Twenty-eight percent of the patients experienced severe systemic infection. The mean interval between the SARS-CoV-2 infection and neurological presentation was 18 days. Pain and sensorimotor deficits were the most common (57%). Spinal epidural hematoma (EDH) was the most common presentation (71.4%). Three patients were treated conservatively, while 4 received neurosurgical intervention. Pain and sensorimotor deficits had the best treatment response (100%), while the sphincter had the worst response (0%). Long-term follow-up showed that 71% of patients had good recovery. SARS-CoV-2-associated SSH is a rare complication of infection, with an often insidious presentation that requires high clinical suspicion. Patients with SARS-CoV-2 infection and new neurological symptoms or disproportionate neck or back pain require a neuroaxis evaluation. Neurosurgical intervention and conservative management are both viable options to treat SSH following COVID-19. Still, a homogenous approach to the treatment paradigm of SSH cannot be obtained, but lesions with space-occupying effects are suitable for neurosurgical evacuation-decompression while more indolent lesions could be treated conservatively. These options should be tailored individually until larger studies provide a consensus.

An Unusual Case of Acute Scrotal Pain

Patients frequently present to the emergency department with complaints of scrotal or testicular pain. Generally, there is an algorithmic approach to workup, which includes assessment for torsion, infection, or vascular causes, and musculoskeletal causes of pain are also sometimes considered. Spinal cord pathology, however, is less often explored as a cause of testicular pain. Here, we present a case of a 45-year-old man with end-stage renal disease and hypertension who presented with acute testicular pain. After a comprehensive workup, however, the source of pain was not initially found. Progression of the patient's symptoms led to the diagnosis of spontaneous spinal subdural hematoma. This atypical presentation of a rare diagnosis is also interesting due to the patient's concomitant diagnosis of an otherwise asymptomatic COVID-19 infection. While our case represents an atypical combination of clinical features, it also illustrates the importance of continued vigilance and ongoing workup when patients present with severe pain and unclear causes of their symptoms.

A Zebra Diagnosis: A Case of Spontaneous Hematomyelia Associated With COVID-19

Spontaneous non-traumatic spinal hematomyelia, characterized by intramedullary spinal hematoma, is a rare neurological emergency. Bleeding arteriovenous malformation, coagulopathies, and neoplasms are reported causes of this rare diagnosis. The authors present a case of a previously healthy man who presented with acute paraplegia and was found to have a spontaneous hematomyelia in association with covid infection. He underwent laminectomy and hematoma evacuation but did not recover any neurological function.

Spontaneous intramedullary hematoma following COVID-19 vaccination: A case report

A 67-year-old female was hospitalized due to right-sided hemiparesis and neck pain with rapid deterioration to a deep coma. She had received the Sinopharm vaccine 2 days earlier. MRI showed extensive cervicothoracic hematomyelia. She received intensive medical care for 2 months and was discharged. An 18-month follow-up showed significant neurological recovery.
