Case Report: A Case of a Child With Facial Foreign Body Abscess and Facial Artery Pseudoaneurysm
Abstract
Facial artery pseudoaneurysms are rare and mostly a result of blunt injury. Since the facial arteries are well protected by facial soft tissue and the lumen of the facial artery is thin and small in diameter, a sharp injury usually leads to complete transection rather than partial laceration of the blood vessel. As a non-invasive method, ultrasound does not involve radiation and sedation. Diagnosis of facial artery pseudoaneurysms is most commonly made with ultrasound, and Doppler ultrasound is essential. On grayscale imaging, facial artery pseudoaneurysms often appearanced of a fluid collection, Color Doppler imaging often show a well-defined swirl pattern named “yin and yang sign,” the Spectral Doppler showed a diagnostic “to and fro” two-phase bidirectional arterial blood flow spectrum. It’s particularly for the examination of facial artery pseudoaneurysms in children. Here, we report a case of facial foreign body abscess and facial artery pseudoaneurysm in a 19-month-old child 1 week after a sharpness injury that was diagnosed by ultrasound.
