Spontaneous Pseudoaneurysm of an External Carotid Artery Branch Presenting as a Parotid Mass: A Case Report and Literature Review

ABAhmet BozerIzmir University MAMelda ApaydınIzmir University

Key Points

The case revealed a rare pseudoaneurysm mimicking a parotid mass in a 65-year-old female, requiring precise imaging.
Initial imaging identified a 3 cm lesion, and Doppler ultrasound confirmed the pseudoaneurysm as a vascular anomaly.
CT angiography ruled out a true aneurysm, indicating the importance of imaging in differential diagnosis of parotid masses.
Conservative management was effective, and follow-up imaging showed no progression, highlighting the benign nature of this case.

Abstract

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.
