Imaging findings of penetrating spinal cord injuries secondary to stab wounds on magnetic resonance imaging in a tertiary trauma unit, South Africa

A Study of the Role of Magnetic Resonance Imaging in the Evaluation of T2-Weighted Hyperintensities in Spinal Cord in a Tertiary Care Hospital in Central India

Background T2-weighted hyperintensities in the spinal cord are crucial markers for diagnosing a range of spinal cord pathologies. This study explores the prevalence, causes, and implications of these hyperintensities in patients with spinal cord injuries at a tertiary care hospital in Central India. The research aims to assess the utility of MRI in detecting T2-weighted hyperintensities in the spinal cord and to analyze the associated clinical and radiological characteristics. Materials and methods A prospective observational study was conducted involving patients referred to the Department of Radiodiagnosis at Acharya Vinoba Bhave Rural Hospital (AVBRH), Sawangi (Wardha), with suspected or confirmed spinal cord injuries. Advanced MRI techniques, including T2-weighted imaging, were used for the evaluation. The study analyzed demographic data, clinical features, and MRI findings to identify common causes and patterns of T2-weighted hyperintensities. Results The study revealed that T2-weighted hyperintensities were present in 54 (72%) MRI scans of patients with spinal cord pathologies at our tertiary care hospital in Central India. Among these, multiple sclerosis was the most frequent diagnosis, accounting for 27 (35%) cases. Traumatic spinal cord injuries were observed in 25% (n=19) of patients, while transverse myelitis was found in 15 (20%). The remaining 15 (20%) included a variety of other conditions, such as infections and tumors. The extent and distribution of T2-weighted hyperintensities varied significantly among different diagnoses, with multiple sclerosis and transverse myelitis demonstrating a more extensive involvement compared to trauma-related cases. Conclusion MRI is a valuable tool for diagnosing and understanding the underlying causes of spinal cord hyperintensities. The study highlights the need for targeted diagnostic and therapeutic approaches based on MRI findings to improve patient outcomes in spinal cord injuries.

Brown-Séquard Syndrome Following a Thoracic Spine Stab Wound: A Case Report

Nonmissile penetrating spine injury represents a small percentage of spinal cord injuries (SCIs), estimated at 0.8% in Western countries. This paper presents a detailed case report of a 28-year-old man with a history of substance use who suffered multiple injuries following a violent incident. The patient was found with a knife embedded in his thoracic spine, prompting immediate medical intervention. Computed tomography and postoperative magnetic resonance imaging revealed the extent of spinal cord and anatomical involvement. A thorough physical medicine and rehabilitation evaluation was conducted post-surgery, leading to a diagnosis of Brown-Séquard syndrome with associated sensorimotor deficits. This paper highlights the challenges posed by penetrating SCIs while reviewing the literature.

The role of tertiary neurosurgical intervention in non-missile penetrating injuries of the spine

PURPOSE

The objective of the study was to determine whether all patients with spinal non-missile penetrating injuries (NMPIs) need to be managed at a tertiary neurosurgical centre.

METHODS

A retrospective analysis of clinical, demographic, and imaging records was performed on all NMPI patients referred to the Department of Neurosurgery at Tygerberg Academic Hospital in Cape Town, South Africa, between 1 January 2016 and 31 December 2019.

RESULTS

Ninety-six patients were identified (94 males and 2 females) with 35 cervical, 60 thoracic, and 1 lumbar spinal stab. Eighty-six had an incomplete spinal cord injury. Six patients presented with cerebrospinal fluid (CSF) leak, all of which resolved spontaneously. MRI was performed in nine patients. Six patients had retained blades, of which 5 were removed in the emergency room (ER). Surgery was performed in two patients (cervical intramedullary abscess and a retained blade). Two patients developed meningitis, and one an intramedullary abscess. Twenty-two patients had associated injuries (pneumothorax, bowel injury). The average length of stay was 17 days, with 81% being unchanged neurologically. The average time from discharge to leaving the hospital was 11 days.

CONCLUSION

Early management of NMPI should include prophylactic antibiotics and wound debridement and X-ray imaging to exclude retained blades. Bowel and lung injury must be managed accordingly. Tertiary neurosurgical referral is not routinely necessary and is only warranted for deteriorating neurology, retained blades not removable in the ER, and respiratory failure secondary to spinal cord injury. Complications include meningitis and persistent CSF leak, which should be referred timeously.
