Microsurgery remains the gold standard treatment for intraventricular lesions, but it is not without limitations. The cerebral ventricles approach is considered a challenge for neurosurgeons because of their deep location and their intimate association with critical areas of the brain. It has been shown that direct endoscopic view is superior to magnetic resonance imaging (MRI) in identifying intraventricular structures and lesions. Also, during neuroendoscopy, there is no cerebrospinal fluid leak causing brain collapse as seen in microsurgery...

BACKGROUND: Skull base meningoencephaloceles are a rare condition, frequently secondary to traumatic or iatrogenic causes. Cerebrofacial arteriovenous metameric syndrome (CAMS) is characterized by the presence of retinal, facial and cerebral arteriovenous malformations (AVMs) with metameric distribution. To the best of our knowledge, this is the first reported case associating these two conditions. CASE DESCRIPTION: A 45 years old female previously diagnosed with CAMS type 2 presented with a long history of cerebrospinal fluid (CSF) rhinorrhea...

OBJECTIVE The CO2 laser has been used on an intermittent basis in the microsurgical resection of brain tumors for decades. These lasers were typically cumbersome to use due to the need for a large, bulky design since infrared light cannot be transmitted via fiber-optic cables. Development of the OmniGuide cable, which is hollow and lined with an omnidirectional dielectric mirror, has facilitated the reintroduction of the CO2 laser in surgical use in a number of fields. This device allows for handheld use of the CO2 laser in a much more ergonomically favorable configuration, holding promise for microneurosurgical applications...

The glymphatic system plays a key role for clearance of waste solutes from the rodent brain. We recently found evidence of glymphatic circulation in the human brain when using magnetic resonance imaging (MRI) contrast agent as cerebrospinal fluid (CSF) tracer in conjunction with multiple MRI acquisitions (gMRI). The present study explored the hypothesis that reduced glymphatic clearance in entorhinal cortex (ERC) may be instrumental in idiopathic normal pressure hydrocephalus (iNPH) dementia. gMRI acquisitions were obtained over a 24-48 h time span in cognitively affected iNPH patients and non-cognitively affected patients with suspected CSF leaks...

PURPOSE: Traumatic meningoencephalocele primarily occurs as a rare but complex complication of cranial base and orbital roof fractures. Traumatic intraorbital meningoencephalocele, which is rare and easily overlooked, can be life-threatening since cephalomeningitis occurs due to cerebrospinal fluid (CSF) leakage. It is obscure for the operative indications or standard surgical methods of traumatic meningoencephaloceles since the combined intricate craniofacial and basal fractures, brain injury, and CSF leak may exist...

BACKGROUND: Spontaneous intracranial hypotension (SIH) is often misdiagnosed, and can lead to severe complications. Conventional MR sequences show a limited ability to aid in this diagnosis. MR-based intracranial pressure (MR-ICP) may be able to detect changes of intracranial elastance and pressure. PURPOSE: To determine whether MR-ICP is able to differentiate SIH patients from normal subjects, improve diagnostic sensitivity, and provide an insight into the pathophysiology...

Penetrating spinal injuries by wood are infrequently reported. They are particularly rare in children. Only 6 cases of wooden fragments causing penetrating intradural spinal injury have been reported. The authors report a case of a 3-year-old girl who suffered a penetrating wound on her lower back after sliding on a wood floor. A portion of the extraspinal part of the wooden splinter was removed prior to presentation; however, a high suspicion for retained foreign body was maintained. Findings on CT were equivocal, but the diagnosis was confirmed on MRI...

Cerebrospinal fluid (CSF) leak occurs due to a defect in the dura and skull base. Trauma remains the most common cause of CSF leak; however, a significant number of cases are iatrogenic, and result from a complication of functional endoscopic sinus surgery (FESS). Early diagnosis of CSF leak is of paramount importance to prevent life-threatening complications such as brain abscess and meningitis. Imaging plays a crucial role in the detection and characterization of CSF leaks. Three-dimensional, isotropic, high resolution computed tomography (HRCT) accurately detects the site and size of the bony defect...

BACKGROUND: Intraoperative cerebrospinal fluid (CSF) leaks are a frequent cause of morbidity in patients undergoing transsphenoidal surgery. This prospective study was performed to examine the impact of intraoperative lumbar subarachnoid drainage (LSAD) on the incidence of this complication and on the extent of resection in patients undergoing endoscopic transsphenoidal surgery for pituitary adenomas. MATERIALS AND METHODS: This prospective study was conducted in a single large academic medical center...

Non-functional pituitary adenomas (NFPAs) are benign tumors of the pituitary gland that do not over-secrete hormonal products, therefore, they are generally detected through symptoms of mass effect, including headache, vision loss, or hypopituitarism. There are multiple pathological subtypes of NFPAs, such as null cell adenomas, silent gonadotrophs, silent somatotrophs, silent corticotrophs, and silent subtype 3, all of which can be classified based on immunohistochemical studies and electron microscopy. Despite these numerous pathological subtypes, surgical resection remains the first-line treatment for NFPAs...

A 55 year old full time employed lady presented with urinary urgency and occasional lower extremity numbness and tingling with motor function preservation. CT and MRI revealed a 20mm x 9mm T10-T11 calcified disc (Figure A, B, C). Anterior and posterior approaches were discussed with the patient along with associated risks such as CSF leak due to possible intradural extension and small but possible risk of new onset motor deficit following disc removal. Considering her almost intact neurological function and to avoid slight albeit realistic morbidity from attempted discectomy regardless of an anterior transthoracic or posterolateral approach, a strategy consisting of a wide long segment T10-T11 laminectomy and T9-T12 posterior instrumented fusion was performed with the assumption that micro motion elimination through a fusion will eliminate dynamic compression from spinal cord draping over the anterior calcified disc fragment...

OBJECTIVE: Craniopharyngiomas can be a surgical challenge for the pediatric neurosurgeon. Ideally, total removal must be achieved. However, the need to reduce surgical morbidity and preserve quality of life has led to a number of neurosurgical approaches in order to attain this goal. The aim of this article is to present an alternative surgical approach to these lesions and to provide the rationale for this technique. MATERIAL AND METHODS: Medical charts and operative records of eight pediatric patients harboring craniopharyngiomas who underwent surgical treatment using a supraorbital eyebrow approach (SOA) were reviewed from 2014 to 2016...

Objective  Spontaneous cerebrospinal fluid rhinorrhea (SCSFR) might be the only clinical manifestation of idiopathic intracranial hypertension (IIH), which has been historically related to overweight. Our goal was to search for an association between SCSFR and increased body weight on the one hand and SCSFR and imaging findings suggestive of IIH on the other hand. Materials and Methods  We retrospectively collected clinical and radiological data of patients operated on endoscopically for SCSFR in our institution from 1993 to 2013...

BACKGROUND: The technique for decompression of Chiari type I malformation relies on open exposure of craniocervical junction for suboccipital craniectomy and upper cervical laminectomy with or without duraplasty. There is no detailed technical report of a minimally invasive approach for Chiari decompression in adults. OBJECTIVE: To describe a mini-open technique for decompression of Chiari type I malformation (including duraplasty) in adults. METHODS: Six consecutive adult patients with symptomatic Chiari type I malformation underwent decompression through a 3 to 4 cm midline incision via a speculum retractor...

OBJECTIVE: Spinal cord stimulation (SCS) is a safe, reversible surgical treatment for complex regional pain syndrome and failed back surgery syndrome refractory to conventional medical management. Paddle electrodes are routinely used for the permanent implant because of the reduced risk of migration, lower energy requirements, and expanded coverage options. The risks associated with paddle lead removal are not well defined in the literature. METHODS: We retrospectively reviewed the outcomes of all patients at the Cleveland Clinic who underwent removal of SCS paddle electrodes between 2009 and 2016...

OBJECTIVE: Targeted epidural blood patch (EBP) at the site of a presumed cerebrospinal fluid leak reportedly has better outcomes than non-targeted EBP; however, it is associated with a higher risk of wrong-site injection, such as iatrogenic subarachnoid or intramuscular injections, which lead to reintervention because of the insufficient coverage of injected blood. METHODS: Eight patients with intracranial hypotension owing to a CSF leak diagnosed with myelographic computed tomography (CT) and thin-cut magnetic resonance imaging (MRI) received an epidural blood patch under O-arm-guided stereotactic navigation...

BACKGROUND: Spinal cord transection is a radical but effective treatment for highly selective cases of symptomatic spinal retethering in paraplegic spina bifida patients. Autonomic dysreflexia (AD) is a potentially life-threatening syndrome involving a dysregulated sympathetic discharge reflex commonly seen following cervical and high thoracic spinal cord injury, leading to a disconnect between autonomic pathways above and below the lesion that can lead to severe complications including uncontrolled hypertension, bradycardia, stroke, and potentially death...

INTRODUCTION: The Expanded Endonasal Approaches (EEAs) have been widely used for various skull base lesions. The reconstruction of the skull base defects is of vital importance to prevent postoperative complications. The vascular pedicled-nasoseptal flap (Hadad-Bassagasteguy flap) is used as a workhorse in reconstruction of majority of the defects. AIM: The purpose of this study was: (a) To assess the postoperative MRI appearance of vascularised pedicled nasoseptal flap for its viability; (b) To determine the variations in MRI that may suggest potential flap failure...
