Abstract
This case report describes a rare spontaneous pseudoaneurysm of an external carotid artery (ECA) branch presenting as a parotid mass in a 65-year-old female. Initial imaging for right sixth cranial nerve palsy incidentally identified a 3 cm parotid lesion. Doppler ultrasound revealed a pseudoaneurysm, confirmed by computed tomography (CT) angiography, demonstrating thrombosed areas and ruling out a true aneurysm. Conservative management was pursued with no progression on follow-up imaging. This case highlights the diagnostic value of Doppler ultrasound in differentiating vascular anomalies and reinforces the need to consider pseudoaneurysms in the differential diagnosis of parotid masses for timely management.
期刊介绍：
The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography.
The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents.
JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
