Diffusion MRI (dMRI) tractography is currently the only imaging technique that allows for non-invasive delineation and visualisation of white matter (WM) tracts in vivo prompting rapid advances in related fields of brain MRI research in recent years. One of its major clinical applications is for pre-surgery planning and intraoperative image guidance in neurosurgery, where knowledge about the location of WM tracts nearby the surgical target can be helpful to guide surgical resection and optimise surgical outcomes...

Gordon Holmes syndrome (GHS) is an autosomal recessive disease characterized by cerebellar ataxia and hypogonadotropic hypogonadism. Among the genes associated with this syndrome, mutations in PNPLA6 have been detected and correlated with the phenotype of GHS. We report a case of a patient affected with GHS, confirmed by physical, neurological, laboratory and genetic analyses. Two compound heterozygous missense mutations on the PNPLA6 gene described as probably damaging/damaging in multiple in silico predictive tools have been detected with massive multigene sequencing...

BACKGROUND: Skull base meningiomas represent a challenge for neurosurgeons and the procedures are typically performed by experienced neurosurgeons, thus limiting resident training. A new simulation and rehearsal device can be used as an aid for senior surgeons during these operations and serve as a training tool for junior surgeons. METHODS: 40 patients harboring an anterior/middle fossa meningioma were recruited. Surgical Theater™, a rehearsal/simulation platform, was used for preoperative planning and intraoperative 3D navigation on 20 patients (CT-MADE group), while the remaining (control group) underwent a traditional navigation...

Cerebellar Mutism syndrome (CMS) is one the most disabling post-operative neurological complications following posterior fossa surgery in children. It is characterised by a transient mutism with a typical onset demonstrated within two days post-operatively accompanied by associated ataxia, hypotonia, irritability. Several hypotheses for anatomical basis of pathophysiology and risk factors have been suggested, however, a definitive theory and treatment protocols are yet to be determined. Animal histological and electrophysiological studies and more recent human imaging studies have demonstrated the existence of compartmentalised representation of cerebellar functions, the understanding of which may shed further light onto the pathophysiology...

Chordomas are rare, slow-growing malignant tumors. Given the paucity of data of the disease, the treatment strategies are disputed. We collected clinical and survival information of patients with chordoma diagnosed between 1975 and 2016 from the Surveillance, Epidemiology, and End Results database. A total of 1797 patients were initially enrolled, including 762 (42.4%) cranial and 1035 (57.6%) spinal chordoma. A total of 1504 patients were further evaluated after screening. In the cranial group, the surgery (gross total resection (GTR): p = 0...

Cavernous malformations (CMs) of central nervous system are vascular malformations usually localized in the brain and rarely in the spinal cord. To date, these malformations are well studied. However, some problems of the management of this pathology are still unresolved. This is due to rare localization of intramedullary CMs in the spinal cord and difficult treatment of spinal pathology per se. To date, about 1000 cases of spinal CM are described in the literature. This review is devoted to natural course of disease and postoperative outcomes...

The authors report a patient with recurrent bifocal germinoma of the optical nerves and chiasm after previous combined treatment. The tumor resulted progressive visual acuity loss despite subsequent therapy (glucocorticoid therapy, chemo- and radiotherapy). Differential diagnosis between tumor progression and consequences of radiotherapy was complicated by MRI negative pattern. Subsequent development of the process, signs of anterior visual pathway damage and tumor spread throughout the ventricular system and subarachnoid spaces according to neuroimaging data indicated recurrence of disease...

The authors report resection of anaplastic convexital meningioma in a middle-aged woman complicated by expected massive blood loss. The most intense bleeding occurred at the final stage of resection and it was impossible to stop it with traditional approaches. The surgeon pressed a standard tachocomb plate moistened with a diluted solution of recombinant activated factor VII (coagil, Russia) to the most bleeding area for 5 minutes. Subsequently, surgeon replaced finger pressure with a permanent napkin. Hemostatic effect of recombinant activated factor VII following its systemic administration is well known and convincingly proven in many surgical areas including neurosurgery...

Surgical treatment of spine and spinal cord diseases is one of important objectives in modern neurosurgery. Patient safety is a priority in spine and spinal cord surgery. Intraoperative imaging ensures efficacy and safe surgery with and without stabilization, preoperative marking, control of decompression and correct implant placement. Surgical C-arms and intraoperative cone-beam CT scanners are the most widespread in everyday practice. The latest achievement was intraoperative spiral computed tomography. C-arms and CT scanners with intraoperative navigation increase the efficiency and safety of surgical interventions...
