Imaging Manifestations of Cervical Internal Jugular Pseudoaneurysm: A Case Report.

Pseudoaneurysm is a relatively rare venous disease characterized by increased intravascular pressure leading to the rupture of the venous wall. Blood flows through the rupture into the surrounding loose connective tissue, where it is encapsulated by fibrous tissue, forming a localized hematoma with a communication channel to the venous vessel, thus forming a pseudoaneurysm. Currently, there are few reports on its imaging manifestations both domestically and internationally. This article reports a case of imaging manifestations of pseudoaneurysm of the right internal jugular vein and analyzes its characteristics.
