Reproducibility of a new classification of the anterior clinoid process of the sphenoid bone
Date of publication: 12-Sep-2020
Background: Pneumatization of the anterior clinoid process (ACP) affects paraclinoid region surgery, this anatomical variation occurs in 6.6–27.7% of individuals, making its preoperative recognition essential given the need for correction based on the anatomy of the pneumatized process. This study was conducted to evaluate the reproducibility of an optic strut-based ACP pneumatization classification by presenting radiological examinations to a group of surgeons.
Coexisting arachnoid cyst and tentorial sinus: A therapeutic dilemma
Date of publication: 12-Sep-2020
Abstract
A 4-year-old male presented with a large arachnoid cyst over the left temporal region causing displacement of adjacent structures. Cerebral angiography showed dilatation of the tentorial sinus without other apparent vascular alterations. The association of these two anomalies raises a therapeutic dilemma as no information is available about how the variants of the venous system can modify cerebrospinal fluid hydrodynamics and thus affect arachnoid cyst’s prognosis. In this case, the patient was treated conservatively and has remained stable for 2 years.
Metastatic epidural spinal column compression due to pancreatic ductal adenocarcinoma causing subacute Cauda equina syndrome: A case report
Date of publication: 05-Sep-2020
Background: Pancreatic ductal adenocarcinoma (PDAC) is the most common pancreatic malignancy, which rarely metastasizes to the spine.
Does surgical decompression alleviate neglected cauda equina syndromes attributed to lumbar disc herniation and/or degenerative canal stenosis?
Date of publication: 05-Sep-2020
Background: Most studies recommend urgent decompression (e.g., within 48–72 h) of the symptomatic onset of a cauda equina syndrome. As patients in our area typically underwent >3 months delayed surgery for cauda equina syndromes due to disc disease/stenosis, we asked whether surgery was still worthwhile.
Unilateral blindness following superior laryngeal nerve block for awake tracheal intubation in a case of posterior cervical spine surgery
Date of publication: 05-Sep-2020
Background: 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.
Diffusion tensor imaging of the spinal cord status post trauma
Date of publication: 05-Sep-2020
Background: 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. 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.
Intramedullary spinal cord cavernous malformations in the pediatric population
Date of publication: 05-Sep-2020
Background: 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.
Aneurysmal bone cyst of thoracic spine with neurological deficit and its recurrence treated with multimodal intervention – A case report
Date of publication: 05-Sep-2020
Background: 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, en bloc excision with reconstruction, and radiotherapy.

Long-term follow-up of lateral ventricular central neurocytoma treated with subtotal resection followed by concurrent chemoradiotherapy and add on chemotherapy – Case report from a Tertiary Kenyan Cancer Hospital
Date of publication: 05-Sep-2020
Background: Central neurocytomas are rare, mostly benign neuroectodermal tumors of the central nervous system typically located within the lateral and third ventricles of cerebrum. No consensus guidelines for the management of central neurocytoma available due to the rarity of the disease.
