Extracranial Intraluminal Extension of Atypical Meningioma within the Internal Jugular Vein

Extracranial Extension of Intracranial Atypical Meningioma En Plaque with Osteoblastic Change of the Skull

Meningioma is a common primary tumor of central nervous system. However, extracranial extension of the intracranial meningioma is unusual, and mostly accompanied the osteolytic change of the skull. We herein describe an atypical meningioma having extracranial extension with hyperostotic change of the skull. The patient was a 72-year-old woman who presented a large mass in the right frontal scal...

The Impact of Intraluminal Vancomycin Adminstration on Prevention of Hemodialysis CatheterRelated Infections

Introduction: Percutaneously inserted double-lumen central venous hemodialysis catheters provide the nephrologist with an excellent temporary access for an immediate hemodialysis treatment and preserve the peripheral veins for the future creation of a permanent arteriovenous vascular access. Unfortunately catheterrelated infections are usually common. In this study, the impact of intra luminal ...

Ultrastructure of internal jugular vein defective valves

OBJECTIVES To study the ultrastructure of intraluminal defects found in the internal jugular vein by using a scanning electron microscopy. METHODS Using a scanning electron microscopy, intraluminal septa and/or defective valves blocking the flow in the distal internal jugular vein of seven patients were studied together with the adjacent wall and compared with control specimen. RESULTS The ...

Jugular Foramen Meningioma with Transverse and Sigmoid Sinuses Invasion and Jugular Vein Extension.

Anatomical variants of the emissary veins: unilateral aplasia of both the sigmoid sinus and the internal jugular vein and development of the petrosquamosal sinus. A rare case report.

We report a case of hypoplasia of the right transverse sinus and aplasia of the ipsilateral sigmoid sinus and the internal jugular vein. In addition, development of the petrosquamosal sinus and the presence of a large middle meningeal sinus and sinus communicans were observed. A 53-year-old Caucasian woman was referred for magnetic resonance imaging (MRI) investigation due to chronic headache. ...
