Delayed cyst formation after radiosurgery for arteriovenous malformation: A case report and critical review.

Background: Stereotactic radiosurgery (SRS) is a validated treatment option for cerebral arteriovenous malformations (AVMs), even if a greater knowledge of its potential delayed complications is still being acquired.

Case Description: A 49-year-old man suffered multiple episodes of cerebral hemorrhage in an approximate 10-year follow-up interval in the context of a left central core AVM with deep venous drainage into the internal cerebral veins (Spetzler Martin Grade 4) despite being treated with gamma knife radiosurgery at two separate timepoints, and with an almost complete obliteration confirmed. Approximately 10 years after the first radiosurgery treatment, he developed severe motor aphasia, Grade 3 right hemiparesis, progressive confusion, and memory deficits.

Survival Determinants in Glioblastoma: An Insight into Biopsy-Only Patient Outcomes.

Glioblastoma is a challenge in neuro-oncology, with survival significantly influenced mainly by the extent of resection and molecular markers. Despite advancements, the prognosis for IDH-wildtype glioblastoma remains poor, particularly when surgical resection is not possible. However, some patients exhibit unexpectedly extended survival despite the extent of resection.

Sequential Evaluation of Hematology Markers as a Prognostic Factor in Glioblastoma Patients.

In our study, we investigated the prognostic significance of hematological markers-NLR (Neutrophil-to-Lymphocyte Ratio), PLR (Platelet-to-Lymphocyte Ratio), and RDW-CV (Red Blood Cell Distribution Width-Coefficient of Variation)-in 117 glioblastoma patients. The data collected from January 2016 to December 2018 included demographics, clinical scores, and treatment regimens. Unlike previous research, which often examined these markers solely before surgery, our unique approach analyzed them at multiple stages: preoperative, postoperative, and before adjuvant therapies.

Cerebral Venous Thrombosis in Patients With Traumatic Brain Injury: Epidemiology and Outcome.

The natural history and epidemiological aspects of traumatic cerebral venous thrombosis (CVT) are not fully understood. Due to the concomitant occurrence with intracranial hemorrhages, guidelines for medical treatment have been highly controversial. In this study, our objective was to carry out an analysis description of the population and to conduct a literature review.

Primary Central Nervous System Lymphoma Mimicking the Presentation of Pituitary Apoplexy: A Case Report.

Pituitary lymphoma is one of the rare variants of primary central nervous system lymphoma (PCNSL), mostly arising due to the metastatic spread of systemic lymphoma. We report the case of a 69-year-old woman who initially presented to her family physician with a headache but without any other symptoms. The MRI scan revealed a sellar mass consistent with a pituitary macroadenoma.

Real Spinal Cord Injury Without Radiographic Abnormality (SCIWORA) in Pediatrics: A Clinical Case Report and Literature Review.

Spinal cord injury without radiological abnormality (SCIWORA) was first reported in 1974. The term was used to define "clinical symptoms of traumatic myelopathy without signs of fracture or spine instability on X-ray or CT scan." With the emergence of MRI, the gold standard method to identify spinal cord injuries, about two-thirds of former SCIWORA cases were found to have pathological findings, and, as such, the term has taken on an ambiguous meaning in the literature.

The impact of selection bias in the treatment for ruptured anterior communicating artery aneurysms: different results or different patients?

Background: Anterior communicating artery is one of the most frequent locations for the development of intracranial aneurysm. The availability and advances of different treatments modalities allows for case-specific selection, but potentially impacts our ability to assess equipoise among them.

Objective: Investigate and compare clinical and morphological variables among surgical and endovascular treatment groups with ruptured anterior communicating artery aneurysms.

The infratentorial supracerebellar approach in surgery of lesions of the pineal region.

Background: Surgery of pineal region lesions is considered a challenging task, due to the particular relationship of lesions in this location with neural and vascular structures. Few series with a significant experience of dealing with these patients have been reported.

Methods: We review our experience using infratentorial supracerebellar approach in the surgery of pineal region, regarding the extension of the removal, postoperative morbidity, and discussing details of the surgical technique.

Trans-lamina terminalis approach for third ventricle and suprasellar tumours.

Background: The trans-lamina terminalis (TLT) approach to the suprasellar region and third ventricle is complex, with risks of visual and hormonal deficits. However, the postoperative deficits might not be directly related to opening of the lamina terminalis but to the close relationship of tumours with vital neural and vascular structures. The analysis of results using this approach was the objective of this study.
