Intracerebral Solitary Fibrous Tumor in Collision With Metastatic Colonic Adenocarcinoma.

A collision tumor is a rare neoplastic lesion consisting of two or more coexisting, distinct cell line entities. In this report, we present the case of a 56-year-old male patient with a history of colon cancer who presented to the emergency room with visual deficits that had started about eight months earlier. An ophthalmologic examination reported left homonymous hemianopsia, prompting a brain MRI, which showed a right posterior temporal extra-axial mass concerning intracerebral metastatic colon cancer, in consideration of patient history.

A De Novo Sphenoparietal Dural Arteriovenous Fistula: Unveiling the Deceitful Culprit.

Introduction: Intracranial dural arteriovenous fistulas (DAVFs) are an uncommon pathology, and a sphenoparietal drainage pattern is certainly rare. We present a case of a de novo sphenoparietal DAVF in a prepubescent patient previously treated for a cerebellar arteriovenous malformation (AVM) 10 years before.

Case Description: A 10-year-old boy presented with worsening headaches for the past few weeks, swelling of the right side of face and eye, and chemosis and proptosis of the right eye.

Stent-assisted coiling of cerebral aneurysms using the Y-stenting technique: a systematic review and meta-analysis.

Background: Bifurcation aneurysms can be treated with stent-assisted coiling using two stents in a Y-configuration. We aim to investigate the angiographic and clinical outcomes of Y-stent constructs for the treatment of intracranial aneurysms.

Methods: A systematic review of PubMed, Ovid MEDLINE, and Ovid EMBASE databases was conducted based on PRISMA guidelines.

Clinical Outcomes of Endovascular Thrombectomy in Tissue Plasminogen Activator versus Non-Tissue Plasminogen Activator Patients at Primary Stroke Care Centers.

Background: The effect of intravenous tissue plasminogen activator (IV tPA) administration before endovascular intervention as compared to without at thrombectomy-capable low-volume centers on procedural aspects and patient outcomes has not been investigated.

Methods: Retrospective chart review was performed in all consecutive large vessel cerebrovascular accident patients treated with endovascular therapy at two select rural primary stroke centers between 2011 and 2015. Patients' data regarding age, sex, and medical history, as well as thrombus location by catheter-based cerebral angiography, postprocedural reperfusion status, and clinical outcomes were reviewed.

Evaluation of Outcomes After Endoscopic Endonasal Surgery for Large and Giant Pituitary Macroadenoma: A Retrospective Review of 39 Consecutive Patients.

Background: The endoscopic endonasal approach for pituitary neoplasms has shown similar efficacy compared with the microscopic approach. However, outcomes and complication rates with larger macroadenomas is not as well documented. This study addresses the efficacy and outcome of the fully endoscopic endonasal approach for large and giant pituitary adenomas.
