Pedicled multifidus muscle flaps to treat dural tears due to penetrating spinal stab wounds: Two case reports and a literature review.

Background: Penetrating spinal injuries occasionally lead to dural tears (DT) and cerebrospinal fluid (CSF) leaks that risk both infectious and neurological complications. Here, we reviewed two cases and the literature regarding the safety/efficacy and limitations of repairing traumatic DT utilizing pedicled multifidus muscle flaps.

Case Description: Two males, ages 73 and 50, presented with Brown-Sequard syndromes and DT/CSF fistulas attributed to knife-induced spinal injuries at the D3-D4 and D11-D12 levels.

Utility and Feasibility of a Low-Cost System to Simulate Clipping Strategy for Cerebral Aneurysms Using Three-Dimensional Computed Tomography Angiography with Virtual Craniotomy.

Objective: To assess utility and feasibility of a low-cost system to simulate clipping strategy for cerebral aneurysms using patient-specific surgically oriented three-dimensional (3D) computed tomography angiography with virtual craniotomy.

Methods: From 2017 to 2021, 53 consecutive patients scheduled for aneurysm clipping underwent preoperative planning using 3D computed tomography angiography with virtual craniotomy. The model was oriented in the surgical position to observe the anatomy through surgical corridors.

Atypical and aggressive diffuse leptomeningeal glioneuronal tumor in a young adult: A case report and review of the literature.

Background: DLGNT is a rare tumor, commonly diagnosed in pediatric age; in most cases, the pathology presents a slow and indolent evolution. We present a case report of a young adult affected by DLGNT characterized by aggressive and atypical behavior.

Case Description: A 21-year-old male presented with mild paraparesis and hypoesthesia with a D2 level.

Multimodal Surgical Management of Cerebral Lesions in Motor-Eloquent Areas Combining Intraoperative 3D Ultrasound with Neurophysiological Mapping.

Background:  Resection of tumors adjacent to motor pathways carries risks of both postoperative motor deficit and incomplete resection. Our aim was to assess usefulness and limitations of a multimodal strategy that combines intraoperative ultrasound (iUS) guided resection with intraoperative neurophysiology.

Methodology:  This is a prospective study of 25 patients with brain lesions adjacent to motor areas who underwent intracranial surgery with assistance of the iUS guidance system and intraoperative neurophysiological monitoring and mapping.

Comparison of two different titanium cranioplasty methods: Custom-made titanium prostheses versus precurved titanium mesh.

Background: The aim of this study was to compare the results of two different titanium cranioplasties for reconstructing skull defects: standard precurved mesh versus custom-made prostheses.

Methods: Retrospective analysis of 23 patients submitted to titanium cranioplasty between January 2014 and January 2019. Ten patients underwent delayed cranioplasty using custom-made prostheses; and 13 patients were treated using precurved titanium mesh (ten delayed cranioplasties, and three single-stage resection- reconstructions).

Ethical and therapeutic dilemmas in glioblastoma management during pregnancy: Two case reports and review of the literature.

Introduction: There are no guidelines about the management of glioblastoma multiforme (GBM) during pregnancy: treatment of these patients presents therapeutic and ethical challenges.

Case Description: Two patients, respectively, 28 years old at the 14 week of gestation with a thalamic GBM and 38 years old at the 28 week of gestation with fronto-mesial GBM. Patients and their relatives were deeply informed about the natural history of GBM and potential risks and benefits of surgery, radiotherapy (XRT), and chemotherapy (CTX) for both, mother and fetus.

Delayed diagnosis of post-traumatic aneurysm of distal anterior cerebral artery.

Background: Traumatic intracranial aneurysms (TICA) are often associated with poor prognosis and should be diagnosed as soon as possible to prevent delayed intracranial hemorrhage and high rates of morbidity/mortality related to bleeding. Diagnosis requires a high index of suspicion. The goal of treatment is to exclude the aneurysm issue with surgical or endovascular methods.

Flexible Fiber CO Laser in Microsurgical Treatment of Intraventricular Tumors: Usefulness and Limitations.

Objective: To assess usefulness and limitations of flexible fiber carbon dioxide (CO) laser in the microsurgical treatment of intraventricular tumors.

Methods: We reviewed a series of 9 patients treated with microsurgical resection of intraventricular tumors using a flexible fiber CO laser. The lesions involved the third ventricle (8) and the frontal horn of the right lateral ventricle (1).
