Apr 3, 2023 · Cavernous sinus thrombosis ( CST) is a rare condition, most commonly infectious in nature, and the diagnosis on imaging is not always straightforward. It has high mortality and morbidity rates. Epidemiology. Cavernous sinus thrombosis is rare, with ~4.5 cases per 1,000,000 per year 5 .
Presentation. Two hour history of blurred vision. Patient Data. Age: 25 years. Gender: Female. ct. Non-contrast CT demonstrates dense, distended bilateral superior ophthalmic veins. While there is some periorbital swelling, much more prominent swelling is seen within the left masticator space. Case Discussion.
Mar 3, 2020 · Imaging helps in identifying thrombosis either via direct visualisation of the thrombus/filling defect in cavernous sinus or via indirect signs that include proptosis, dilatation of the draining tributaries and abnormal dural enhancement, that are well demonstrated on contrast enhanced studies [ [7], [8], [9], [10] ].
Cavernous sinus thrombosis (CST) is a fulminant life-threatening disorder that can complicate many pathologies affecting the brain and the orbit. It is usually predicted clinically but MR is an important tool for determining the extent of the disease, associated complications and aetiology of thrombosis.
Apr 12, 2019 · We review the anatomy of the cavernous sinus, along with the imaging technique, the multimodality imaging features of individual pathologic conditions of the cavernous sinus correlating with histopathologic findings, an algorithmic imaging approach to differential diagnosis, and imaging pitfalls.
Jan 1, 2020 · Abstract. Purpose. To determine the role of Contrast enhanced MRI (CEMRI) in the evaluation of Cavernous sinus thrombosis (CST). Method. The study included 7 patients with an imaging diagnosis of cavernous sinus thrombosis.
Aug 20, 2021 · Cavernous sinus thrombosis (CST) is a rare, life-threatening condition that can occur as a result of a face infection, sinusitis, orbital cellulitis, pharyngitis, or otitis media. It can also result from a serious injury or surgery, especially in the presence of a thrombophilic disorder.
Apr 12, 2019 · MRI is the modality of choice to depict the cavernous sinuses, with CT and digital subtraction angiography playing supplementary roles in certain situations. In this article, the cavernous sinus lesions encountered in our institution during a 10-year period are reviewed.
MRI signs of cavernous sinus thrombosis include enlarge- ment of the cavernous sinuses and enhancement of the pe- ripheral margins with central areas of low signal intensity.
The cavernous sinus (CS) contains vital neurovascular structures that may be affected by vascular, neoplastic, infective, and infiltrative lesions arising in the CS proper or via extension from adjacent intra- and extracranial regions.
