The supraclinoid ICA fenestration (SIF) is considered an extremely rare congenital anomaly. However, most of the reported cases of SIF are associated with intracranial aneurysms either ruptured or unruptured. We report the case of a 55-year-old patient with a right SIF and an unruptured, large, wide-necked aneurysm located on the larger limb of the fenestration and a second small aneurysm distal to the SIF. The aneurysms were treated with a Pipeline flow-diverter stent, achieving the complete reconstruction of the anatomy of the carotid siphon...

BACKGROUND: Predicting the fate of patients who are given a misdiagnosis of aneurysmal subarachnoid hemorrhage (aSAH) remains unclear. The purpose was to examine factors associated with initial misdiagnosis of aSAH and to investigate the impact of initial misdiagnosis of aSAH on clinical outcomes. METHODS: Between January 2007 and December 2015, medical records and radiographic data for 3118 consecutive patients with aSAH were reviewed. There were 33 patients who had been documented with an initial misdiagnosis of aSAH, and all met the following criteria: (1) failure to correctly identify aSAH upon initial presentation to health care professionals; and 2) subsequently documented aSAH after the initial misdiagnosis...

BACKGROUND: The use of intraoperative ultrasound (iUS) has increased in the last 15 years becoming a standard tool in many neurosurgical centers. Our aim was to assess the utility of routine use of iUS during various types of intracranial surgery. We reviewed our series to assess ultrasound visibility of different pathologies and iUS applications during the course of surgery. MATERIALS AND METHODS: This is a retrospective review of 162 patients who underwent intracranial surgery with assistance of the iUS guidance system (SonoWand)...

BACKGROUND: Several techniques have been described for the percutaneous treatment of trigeminal neuralgia; however, each has significant drawbacks. We propose a new technique for percutaneous balloon compression of the trigeminal ganglion and distal trigeminal nerve using electromagnetic (EM) neuronavigation. METHODS: The procedure was performed in 17 consecutive patients with trigeminal neuralgia. Patients were then followed up with telephone interview. We also performed a cadaveric validation study to further investigate the accuracy of the technique using dye...

Recurrent chemical meningitis from cyclic leakage of cyst content from a craniopharyngioma is a rare phenomenon. Here, we report a case of leaking cystic craniopharyngioma presenting with recurrent episodes of sterile meningitis, depression, and paranoia. The diagnosis after an initial craniotomy and exploration was hypophysitis. Signs and symptoms were not alleviated by puncture and biopsy of the tumour but they disappeared after complete resection with a final histological diagnosis of craniopharyngioma.

BACKGROUND: Neuromas are pathologic nerve distensions caused by a nerve's response to trauma, resulting in a dysfunctional to non-functional nerve. Depending on the severance of the affected nerve, the resulting neuroma can be differentiated into continuous and stump neuroma. While neuroma formation has been investigated in animal models with enormous regenerative capacity, the search for differences in human response to nerve trauma on a molecular level ultimately seeks to identify reasons for functionally successful versus unsuccessful regeneration after peripheral nerve trauma in man...

BACKGROUND: Surgery has been in a huge development where the aim is to achieve same or better results with less complication in a less invasive way; these minimal approaches can be applied in a very safe way to aneurysmal neurosurgery. METHOD: Images are studied to optimize the patient positioning and the surgical roadmap. After the positioning, the skin incision, craniotomy, and dura incision are performed and intradural lesion is reached. A watertight closure is performed under the microscope...

BACKGROUND: Venous anastomosis is one of the most difficult techniques in vascular neurosurgery. METHOD: We present a simple technique of end-to-end venous anastomosis for reconstruction of accidentally injured vein. A venous catheter was used for the stent during the end-to-end anastomosis. RESULTS: The venous catheter as the stent facilitated confirmation of the ostium of the vein. The venous end-to-end anastomosis was successfully performed...

BACKGROUND: The endoscopic transorbital approach has been recently proposed for the surgical management of spheno-orbital lesions as an alternative to craniotomy surgeries. METHOD: We analyze the technical nuances and what we have changed as our experience increased after the first operations performed for 12 different spheno-orbital lesions. CONCLUSION: The endoscopic transorbital approach is useful for the treatment of selected spheno-orbital lesions and could represent an interesting option in experienced hands...

BACKGROUND: The Wessex Modified Richmond Sedation Scale (WMRSS) has been developed with the aim of improving the early identification of patients requiring decompressive hemicraniectomy for malignant middle cerebral artery syndrome (MMS). The objective of this study was to evaluate the WMRSS against the Glasgow Coma Scale (GCS). METHODS: A retrospective study was conducted of patients admitted to our unit for observation of MMS. Data were obtained on WMRSS and GCS recordings from admission up to 120-h post-ictus...

BACKGROUND: Anterior temporal lobectomy (ATL) as a treatment for drug-resistant temporal lobe epilepsy (TLE) frequently causes visual field deficits (VFDs). Reported VFD encompasses homonymous contralateral upper quadrantanopia. Its reported incidence ranges from 15 to 90%. To date, a quantitative method to evaluate postoperative VFD in static perimetry is not available. A method to quantify postoperative VFD, which allows for comparison between groups of patients, was developed. METHODS: Fifty-five patients with drug-resistant TLE, who underwent ATL with pre- and postoperative perimetry, were included...

Benedikt's syndrome (BS) is caused by the lesion in the midbrain and specifically manifests a series of symptoms, including ipsilateral third nerve palsy, contralateral tremor, hemiataxia, and hyperactive tendon reflexes. Deep brain stimulation (DBS) for BS emerges as a new approach and achieves successfully results. We report a successful case report of thalamic ventral intermediate (VIM) nucleus DBS for a patient with BS. During follow-up of 3 years, DBS successfully control the tremor and greatly improve his living and working quality...

Since the early days of modern neuroscience, psychological models of brain function have been a key component in the development of new knowledge. These models aim to provide a framework that allows the integration of discoveries derived from the fundamental disciplines of neuroscience, including anatomy and physiology, as well as clinical neurology and psychiatry. During the initial stages of his career, Sigmund Freud (1856-1939), became actively involved in these nascent fields with a burgeoning interest in functional neuroanatomy...

BACKGROUND: Neurologic manifestations of craniovertebral junction (CVJ) disease may generate dramatic brainstem damage, which could evolve to paralysis. In most cases, patients are referred with advanced neurological symptoms such as tetraplegia/paresis. The aim of this study was to identify predictive factors of favorable neurological evolution after non-traumatic brainstem compression. METHODS: A prospective study evaluated 143 consecutive patients who had undergone CVJ anterior brainstem decompression...

BACKGROUND: Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord dysfunction, potentially leading to severe disability. Abnormal cervical spine magnetic resonance imaging (MRI) and motor evoked potentials (MEPs) are independent predictors of disease progression. Abnormal MRI is accompanied by various activation changes in functional brain MRI (fMRI), whereas preoperative and postoperative fMRI adaptations associated with abnormal preoperative MEP remain unknown...
