OBJECTIVE The distance to the ventral dura, perpendicular to the basion to C2 line (pB-C2), is commonly employed as a measure describing the anatomy of the craniovertebral junction. However, both the reliability among observers and the clinical utility of this measurement in the context of Chiari malformation Type I (CM-I) have been incompletely determined. METHODS Data were reviewed from the first 600 patients enrolled in the Park-Reeves Syringomyelia Research Consortium with CM-I and syringomyelia. Thirty-one cases were identified in which both CT and MRI studies were available for review...

PURPOSE: To report a case of anterior sacral meningocele with intralesional bleeding secondary to sacrococcygeal trauma. Likewise, there is a discussion about the physiopathology and the surgical approach to these types of lesions. METHODS: A 43-year-old man diagnosed with Marfan syndrome suffered sacrococcygeal trauma. He was admitted to the emergency room due to symptoms of headache, nausea, and lower limb subjective weakness. CT and MRI showed a large retroperitoneal mass with hemorrhagic content close to the sacrum...

BACKGROUND: It can be difficult to make complete burr holes using a perforator with automatic releasing systems in cases of a soft diploe or thick calvarial bone. OBJECTIVE: To demonstrate the utility of a flipped "bone pad" (BP) in recovery of penetration failure when using an automatic releasing perforator. METHODS: For craniotomy or ventricular drainage, the first step is to make 1 or more burr holes using a craniotome. Neurosurgeons sometimes incompletely penetrate the skull using the latest tools...

OBJECTIVE/BACKGROUND: We have anecdotally observed patients with high-flow ventral cerebrospinal fluid (CSF) leaks resulting from penetrating osseous spicules or calcified discs to be relatively thin. The purpose of this study was to explore the validity of this observation and determine if a potential association exists between low body mass index (BMI) and high-flow spinal ventral CSF leaks resulting from such dura-penetrating lesions. METHODS: Sixteen consecutive patients with precisely localized high-flow ventral spinal CSF leaks on dynamic myelography were identified...

BACKGROUND: Dural arteriovenous fistulas (DAVFs) of the craniocervical junction are uncommon vascular lesions, which often require surgical treatment even in the endovascular era. METHODS: Most commonly, the fistula is placed laterally, and surgical ligation is performed through a lateral suboccipital craniotomy. After dural opening, the area is inspected, and the arterialized vein is identified emerging from the dura, often adjacent to the entry point of the vertebral artery, and ligated...

Spinal epidural abscess is an uncommon pathology. It has an incidence of one case per 100 000 individuals. An increase is observed due to the raise of risk factors such as diabetes mellitus, spinal abnormalities, tattoos, acupuncture, epidural analgesia, and a greater availability of imaging methods. It is a purulent collection located between the dura and the medullary canal. The most common germs are Staphylococcus aureus and Gram-negative bacteria. Without timely treatment, it evolves to medullary compression and permanent neurological sequelae...

Traumatic brain injury (TBI) has become a recent focus of biomedical research with a growing international effort targeting material characterization of brain tissue and simulations of trauma using computer models of the head and brain to try to elucidate the mechanisms and pathogenesis of TBI. The meninges, a collagenous protective tri-layer which encloses the entire brain and spinal cord has been largely overlooked in these material characterization studies. This has resulted in a lack of accurate constitutive data for the cranial meninges, particularly under dynamic conditions such as those experienced during head impacts...

Dural injury during spinal surgery can subsequently give rise to a remote cerebellar hemorrhage (RCH). Although the incidence of such injury is low, the resulting hemorrhage can be life threatening. The mechanism underlying the formation of the hemorrhage is not known, but it is mostly thought to develop after venous infarction. Cerebellar mutism (CM) is a frequent complication of posterior fossa operations in children, but it is rarely seen in adults. The development of CM after an RCH has not been described...

This study tried to quantify spinal cord perfusion by using contrast-enhanced ultrasound (CEUS) in rhesus monkey models with acute spinal cord injury. Acute spinal cord perfusion after injury was detected by CEUS, coupling with conventional ultrasound (US) and Color Doppler US (CDFI). Time-intensity curves and perfusion parameters were obtained by autotracking contrast quantification (ACQ) software in the epicenter and adjacent regions of injury, respectively. Neurological and histological examinations were performed to confirm the severity of injury...

Spinal extradural arachnoid cysts are one of the rare causes of symptomatic spinal cord compression. Among them, occurrence of multiple cysts at the same spinal segment is rarely described in the literature. They appear to be extradural outpouchings of arachnoid that communicate with the intraspinal sub-arachnoid space through a small defect in the dura, filled by cerebrospinal fluid. Pathogenesis of these lesions is still unclear. Surgical excision is considered as the gold standard treatment. We present a 7-year-old female child who presented with spastic paraparesis...

Marjolin's ulcer is a well-recognized, rare, long-term complication of post-burn scar and other chronically irritating local skin conditions. Its infiltration into the skull bones and the underlying dura causing complete destruction is very rare and quiet exceptional. We present an unusual case of spontaneous brain fungation through the scar tissue present over the scalp as a result of flame burn 18 years back. Patient was treated surgically, but expired after 10 days. Though we were not able to save the patient, its presentation was so unique that we want to report this case...

Posterior fossa extra-dural hematoma is rare and early diagnosis and management is associated with good outcome. Twenty four year male presented with somnolence and soft tissue swelling of occipital region following road traffic accident. CT scan revealed bilateral posterior fossa with bilateral temporo-occipital Extradural Hematoma (EDH) with mass effect. He was operated through a trifoliate incision and craniotomies leaving a strip of bone over the transverse and occipital sinus. The blood loss with such technique was minimal and the control of sinus tear was easier as the dura on either sides of the sinus can to tied to each other to hitch the sinus up to the bone thereby, providing a good tamponade...

Background Hemicrania continua (HC) is a primary headache syndrome characterized by a unilateral, moderate, continuous headache with exacerbations marked by migrainous and cranial autonomic symptoms. However, clinical phenotypes similar to primary HC may be subtended by several disorders. Case report We report the case of a 62-year-old man experiencing, over the previous year, a headache completely consistent with HC and its absolute responsiveness to indomethacin therapy. Later, the patient developed diplopia caused by sixth cranial nerve palsy ipsilateral to headache...

Incidental durotomy during lumbar spine surgery is a commonly reported complication. Those presenting with cerebrospinal fluid (CSF) leak are usually recognized and repaired intraoperatively. In some circumstances, it may either be unrecognised or occur as a delayed complication. Such delayed occurrences cannot be predicted and its management remain a challenge to the surgeon, especially when it presents as a subdural effusion. We report a 55-year-old man who underwent mini open lumbar discectomy through left side for a prolapsed L4-L5 disc...

Acalvaria is a rare condition indeed, defined as the absence of the flat bones of the skull, as well as the associated muscles and dura, with, in some cases, normal skull base bones and normal brain structures. It has been reported as a fatal congenital condition, because of the failure of afflicted children to survive for extended periods. There have, however, been reports of extended survival. The first report of this condition was in 1996, involving an 11-year-old child who had severe mental retardation...

A detailed quantification and understanding of cerebrospinal fluid (CSF) dynamics may improve detection and treatment of central nervous system (CNS) diseases and help optimize CSF system-based delivery of CNS therapeutics. This study presents a computational fluid dynamics (CFD) model that utilizes a non-uniform moving boundary approach to accurately reproduce the non-uniform distribution of CSF flow along the spinal subarachnoid space (SAS) of a single cynomolgus monkey. A magnetic resonance imaging (MRI) protocol was developed and applied to quantify subject-specific CSF space geometry and flow and define the CFD domain and boundary conditions...
