For 12 patients who originally presented with cauda equina syndrome with complete incontinence, nine exhibited delayed full recovery of bladder function with average of 8.22 months postoperatively. We would, therefore, advise that delayed surgical decompression be offered to these patients, irrespective of the preoperative duration of cauda equina syndromes with complete incontinence.
Superior laryngeal nerve block (SUPLANEB) is a popular airway anesthesia technique utilized for successful awake endotracheal intubation in patients with significant cervical spine instability. If not performed by an expert, it carries the risk of general/neurologic complications that are typically minimal/transient. However, permanent blindness and/or upper cranial nerve neuropathies may occur. Here, we describe a case in which a young patient underwent an atlantoaxial fusion for a C2 nonunion (e.g., following a fracture) complicated by unilateral blindness due to a SUPLANEB.

A 25-year-old neurologically intact male underwent a C1-C2 posterior arthrodesis to address a nonunion of a C2 fracture. To perform the awake nasotracheal intubation, a SUPLANEB was performed using a video laryngoscope. Although the operation was uneventful, postoperatively, the patient reported left visual loss accompanied by left-sided facial numbness and hearing loss. On examination of the left eye, the anterior segment and fundu potential complications of SUPLANEB. Notably, these deficits were not directly related to the operative positioning or neurosurgical spinal procedure.
Since its development in 1994, diffusion tensor imaging (DTI) has been successfully used to assess structural and functional changes to neurological tissue within the central nervous system. Asunaprevir concentration Namely, DTI is a noninvasive magnetic resonance imaging (MRI)-based technique that uses anisotropic diffusion to visualize and estimate the organization of white matter in neuronal tissue. It has been used to study various spinal pathologies including neoplastic diseases, degenerative myelopathy, demyelinating diseases, and infections involving the spinal cord. However, due to technical uncertainties and experimental limitations, DTI has rarely been clinically applied to assess trauma-related spinal pathologies.

An extensive review of the published literature on DTI was performed utilizing PubMed, OVID Medline, and EMBASE journals. Terms used for the search included DTI and spine trauma.

The search yielded full text English language-related articles regarding DTIs application, limitations, and functional outcomes seDTI indices; fractional anisotropy, apparent diffusion coefficient (ADC), longitudinal ADC, and transverse ADC. Using DTI as a diagnostic tool status, post spine trauma has proven useful in examining the morphological and physiological extent of spinal lesions beyond conventional MRI. Experimental studies are now utilizing DTI to analyze the severity of spinal cord trauma during the hyperacute phase and may potentially be used to providing additional diagnostic information for improved treatment efficiency (e.g., as shown during the stem cell therapy trials).
Intramedullary spinal cavernous malformations (ISCM) account for just 1% of all intramedullary pediatric spinal cord lesions. Pathologically, they are well-circumscribed vascular malformations that typically appear dark blue or reddish-brown, often coming to the spinal cord surface. With regard to the histopathology findings, ISCMs are comprised sinusoidal vascular spaces lined by a single layer of endothelial cells within a loose connective tissue stroma. As these lesions are often misdiagnosed in the pediatric population, appropriate treatment may be unduly delayed.

The authors performed an extensive review of the published literature (PubMed) focusing on ISCM in the pediatric age group.

The search yielded 17 articles exclusively pertaining to ISCM affecting the pediatric population.

Here, we reviewed the clinical, radiographic, surgical, and outcome data for the treatment of ISCM in the pediatric age groups. Notably, over 50% of pediatric patients with ISCM experienced an improvement in their neurological status after a mean postoperative follow-up duration of 4 years. Future meta-analyses are needed to highlight the potential presence of ISCM and, thereby, decrease the rate of misdiagnosis of these lesions in the pediatric population presenting with recurrent intramedullary spinal cord hemorrhages.

Aneurysmal bone cysts (ABCs) are rare, representing about 1% of primary bone tumors, and 15% of all primary spine/sacral tumors. Notably, when they are located in poorly accessible regions such as the spine and pelvis, their management may be challenging. Treatment options include selective arterial embolization (SAE), curettage,
excision with reconstruction, and radiotherapy.

A 16-year-old male presented with 2 months of mid back pain, left-sided thoracic radiculopathy, and left lower limb weakness (MRC - 3/5). MR imaging revealed an expansile, lytic lesion involving the T9 vertebral body, and the left-sided posterior elements resulting in cord compression. He underwent SAE followed by intralesional excision, bone grafting, and a cage - instrumented fusion. ABC was diagnosed from the biopsy sample. Postoperatively, the pain was reduced, and he was neurologically intact. Five months later, he presented with a new lesion that was treated with repeated SAE and three doses of zoledronic acid. At the end of 2 years, the subsequent, MRI and CT studies documented new bone formation in the lytic areas, with healing of lesion; additionally, he clinically demonstrated sustained pain relief.

Here, we emphasized the importance of surgery for patients with ABC who develop focal neurological deficits. Treatment options should include SAE with bisphosphonate therapy for lesions that recur without neurological involvement.
