Jugular foramen Radiology Reference Article

The jugular foramen is a complex crossroad of neurovascular structures deep in the skull base. It is inaccessible to clinical examination, and safe surgical approach is often hindered by crucial surrounding structures. Radiology plays a central role in the diagnostic evaluation and management planning of jugular foramen lesions 1. Neurosurgery. 2000 Sep;47(3 Suppl):S267-85. Jugular foramen. Rhoton AL Jr(1).

Terminology. Although the jugular foramen is technically an anatomically distinct entity which connects the jugular fossa to the posterior fossa, both contain the same neurovascular structures and lesions present similarly.As the differential for lesions arising here are the same, for the purposes of this article the terms jugular fossa and jugular foramen will be used interchangeably This page is based on the copyrighted Wikipedia article Jugular_foramen (); it is used under the Creative Commons Attribution-ShareAlike 3.0 Unported License.You may redistribute it, verbatim or modified, providing that you comply with the terms of the CC-BY-SA The jugular foramen is located between the temporal and the occipital bones. It can be regarded as a hiatus between the temporal and the occipital bones (1). The right foramen is usually larger than the left. The foramen is configured around the sigmoid and inferior petrosal sinuses jugular foramen an opening formed by the jugular notches of the temporal and occipital bones. foramen mag´num a large opening in the anterior inferior part of the occipital bone, between the cranial cavity and spinal canal Angiography demonstrated right jugular foramen dAVF with direct brainstem venous reflux (Cognard IV). It was fed from multiple branches of the external carotid artery and the vertebral artery, and draining into the ascending pontomesencephalic vein

The jugular foramen is located between the temporal bone and the occipital bone (Figs. 9.1 and 9.2). The right foramen is usually larger than the left. In a previous study, we observed that the right foramen was larger than the left in 68% of the cases, equal to the left in 12%, and smaller than the left in 20% The jugular foramen, based on these studies of microsurgical anatomy, is divided into three compartments: two venous and a neural or intrajugular compartment. The venous compartments consist of a larger posterolateral venous channel, the sigmoid part, which receives the flow of the sigmoid sinus, and a smaller anteromedial venous channel, the petrosal part, which receives the drainage of the.

Jugular Foramen. The jugular foramen is formed anteriorly by the petrous part of the temporal bone and posteriorly by the occipital bone. It can be considered as three separate compartments with their respective contents: Anterior - contains the inferior petrosal sinus (a dural venous sinus) The jugular foramen syndrome (JFS or Vernet syndrome) refers to paralysis of the IX, X, and XI cranial nerves traversing the jugular foramen. Vernet first described it in the Paris Medical Journal (1917). Etiology. The following etiologies of jugular foramen syndrome have been described in the literature: Congenital: Primary cholesteatom Jugular foramen tumors are rare skull base lesions that present diagnostic and complex management prob-lems.

Glomus jugulare is a rare slow growing tumor occurring within the jugular foramen that rarely presents with isolated symptoms. Although histologically benign, these tumors are locally destructive because of their proximity to the petrous bone, the lower cranial nerves, and the major vascular structures (Miller et al. (2009) and Silverstone (1973)) The jugular foramen courses anteriorly, laterally, and inferiorly as it insinuates itself between the petrous temporal bone and the occipital bone. The jugular foramen is divided by a fibrous or bony septum, the jugular spine, into: the pars nervosa:smaller and anteromedial the pars vascularis:larger and posterolateral Pars nervosa The pars nervosa is the anteromedial portion of the jugular. Medical definition of jugular foramen: a large irregular opening from the posterior cranial fossa that is bounded anteriorly by the petrous part of the temporal bone and posteriorly by the jugular notch of the occipital bone and that transmits the inferior petrosal sinus, the glossopharyngeal, vagus, and accessory nerves, and the internal jugular vein

The tympanic branches of 9th and 10th cranial nerves also pass through jugular foramen. Jugular foramen may be classified into three parts (petrosal, sigmoid and intrajugular part) according to the structures which passed through the jugular foramen The Jugular Foramen: The jugular foramen is a large opening in the base of the skull that houses many important veins and arteries.
