Jul 19, 2024 · The internal jugular vein (IJV) is the major venous return from the brain, upper face and neck. It is formed by the union of inferior petrosal and sigmoid dural venous sinuses in or just distal to the jugular foramen (forming the jugular bulb). It descends in the carotid sheath with the internal carotid artery.

A: Dense right internal jugular vein is noted and is highly suspicious for thrombosis. Comparison made to CT brain from earlier the same day. There is a filling defect in the right internal jugular …

Dec 11, 2016 · Both contrast-enhanced CT (CECT) and ultrasound (US) are useful modalities for assessment of the neck masses, with US offering the opportunity for image-guided fine needle aspiration or core needle biopsy of suspicious masses or lymphadenopathy.

IJV may appear smaller than normal in chronic thrombosis or larger than normal in thrombophlebitis On CT: Hyperdense signal is seen without contrast; non-enhancing clot with contrast; wall-thickening, fat-stranding with inflammation; chronic thrombus has well-defined thrombus and possibly surrounding collateral vessels

To increase the level of awareness of this anomaly among radiologists, we report rarely described multidetector computed tomography (CT) findings in a case of fenestrated IJV.

CT Venography can provide a rapid and reliable modality for detecting IJVthr (Figure 3). CTV is much more useful in subacute or chronic situations because of the varied density in thrombosed sinus.

The aim of this prospective study was to validate the hypothesis that the diameter of the right IJV is greater than the left one, and to determine cross-sectional areas of both IJVs using CT scans and original automatic software.

Contrast-enhanced CT is useful in the diagnosis of thrombophlebitis of the IJV; characteristic CT findings of this unusual entity may be the main clue to the correct diagnosis.

Aug 1, 2012 · However, normal variants and their incidence in the extracranial IJV circulation are not well documented. The purpose of this article is to identify the frequency and cause of extrinsic compression of the upper jugular vein in consecutive unselected patients presenting for CT angiography of the neck.

Jul 19, 2024 · The internal jugular vein (IJV) is the major venous return from the brain, upper face and neck. Gross anatomy Origin and course It is formed by the union of inferior petrosal and sigmoid dural venous sinuses in or just distal to the jugular fo...
