Vasa vasorum: The role in intracranial physiology and pathophysiology.

Background: Vasa vasorum (VVs) is a Latin word representing vessels of vessels. VVs are usually found on the adventitia of the parent vessel and infrequently reach the media and intima, depending on the size and type of the parent vessels and physiological and pathological conditions. The VVs include arteries, capillaries, veins, and lymphatic vessels, involving the oxygenation and nourishment of the vessel's wall to sustain its healthy state.

The Role of Genetic Analysis in Distinguishing Multifocal and Multicentric Glioblastomas: An Illustrative Case.

Introduction: Glioblastomas can manifest as multiple, simultaneous, noncontiguous lesions. We genetically analyzed multiple glioblastomas and discuss their etiological origins in this report.

Case Presentation: We present the case of a 47-year-old woman who presented with memory impairment and left partial paralysis.

A Case of Symptomatic Intraluminal Internal Carotid Artery Thrombus in a Patient with Essential Thrombocythemia Surgically Treated by CEA.

We report a patient with a symptomatic intraluminal internal carotid artery thrombus clinically revealed by cerebral infarction. In the preoperative evaluation, it was revealed that essential thrombocythemia existed in the background. Therefore, medical treatment with antithrombotic agents in conjunction with hydroxycarbamide for essential thrombocythemia was initiated, but the thrombus was not dissolved by three weeks.

A simple combined approach using anterior transpetrosal and retrosigmoid approach: A case report.

Background: A combined transpetrosal approach (CTP) is often used for large lesions in the posterior cranial fossa (PCF). Although CTP provides a wide surgical corridor, it has complex and time-consuming bony work of mastoidectomy and cosmetic issues. Here, we describe a simple combined surgical technique to approach the supratentorial region, anterolateral surface of the brainstem, petroclival region, and foramen magnum by drilling only the petrous apex with a combination of retrosigmoid approach (RA).

A Case of Bilateral Cerebellar Chronic Encapsulated Intracerebral Hematoma with Rapidly Progressive Symptoms.

Chronic encapsulated intracerebral hematoma (CEIH) is a rare cerebrovascular disease featuring progressively expanding intracranial hematoma. We treated a man in his 70s with bilateral cerebellar CEIH. He had presented at another hospital with dizziness, and imaging showed two independent hemorrhagic space-occupying lesions in the bilateral cerebellar hemispheres.
