Newly Diagnosed Adult Basal Ganglia Gliomas Treated With Laser Interstitial Thermal Therapy: A Comparative Cohort With Needle Biopsy.

Background: Few cytoreductive surgical tools are available for newly diagnosed basal ganglia gliomas. Current reports showed high associated morbidity and mortality. Given their deep localization, laser interstitial thermal therapy (LITT) is still a rare indication.

Primary central nervous system lymphoma: Inter-compartmental progression.

There is limited understanding of the inter-compartmental progression and treatment outcomes of primary central nervous system lymphoma (PCNSL). In this multicenter retrospective cohort study on 234 patients with PCNSL (median age: 62.5 years [18-92]; median follow-up 35 months [0.

Scalpel Sign in Spine Pathology: Presentation in 3 Different Rare Diagnoses.

Background: The scalpel sign is a radiological finding observed on sagittal magnetic resonance imaging and computed tomography myelography corresponding to an indentation in the dorsal aspect of the spinal cord resembling a surgical scalpel blade. It is said to be a pathognomonic imaging discovery linked to dorsal arachnoid webs. However, other spine-related conditions may mimic dorsal arachnoid webs on magnetic resonance imaging, such as spinal arachnoid cysts or ventral spinal cord herniation, leading to misdiagnosis.

Cervical laminoplasty with unilateral C4-5 foraminotomy: Technical note and case series.

Objective: The open-door laminoplasty technique is widely used in the treatment of multilevel cervical myelopathy. Despite the satisfactory functional and radiological results of this technique, postoperative C5 palsy is still a severe and disabling complication with a variable incidence in the literature. The objective of this article is to describe and demonstrate the surgical technique step by step with the addition of unilateral C4-5 foraminotomy and to evaluate the results obtained to date, with special emphasis on C5 palsy.

Results in the treatment of intracranial hemangiopericytomas. Case series.

Objective: Intracranial hemangiopericytoma (HPC) is a rare central nervous system tumor characterized by its low incidence, high rate of local recurrence and risk of metastasis. The main objectives of this paper are two: to show the results in the treatment of HPC in our institution in the last 20years and to make a review of the literature on this topic.

Methods: Retrospective review that includes patients diagnosed with intracranial solitary fibrous tumor/hemangiopericytoma (SFT/HPC) that have undergone surgery from 1997 to 2017.

Postcraniectomy pain: comparison between 2 incisions for the retrosigmoid approach. Prospective randomized study.

Background: Suboccipital lateral approach is a common practice in neurosurgery to expose the region of the cerebellopontine angle. Postcraniectomy headache (PCH) is one of the most frequent complications that diminish the quality of life of patients.

Objective: To compare postcraniectomy pain in patients operated on for vestibular neurinomas by a suboccipital lateral approach by 2 different incisions.

The sellar barrier and intraoperative CSF leak in elderly patients.

Cerebral spinal fluid (CSF) leak is a significant complication in pituitary surgery, increasing both patient morbidity and mortality. In a recent publication, Campero et al. observed worse postoperative prognosis and increased risk of intraoperative CSF leak in patients with reduced sellar barrier thickness.

Pituicytoma Associated with Acromegaly and Cushing Disease.

Background: Pituicytoma is a rare neoplasm arising in the sellar region (World Health Organization grade I). Clinically, pituicytomas mimic nonfunctioning pituitary macroadenomas and are occasionally incidentally discovered at autopsy. Pituitary adenomas can occur with other sellar pathologies, and the term "collision sellar lesions" has been coined for this rare entity.

[Placement of ventricle peritoneal shunt in the adult patient. A new protocol].

Introduction: Ventriculoperitoneal shunting is considered a relatively straightforward procedure, though it might ensure multiple complications. Our surgical team developed and implemented a new protocol since June 2016. The objective of this paper is to describe and illustrate the surgical technique step by step and to demonstrate that the use of the "new protocol" significantly reduces the complications associated with the procedure.
