並列摘要


Pseudoaneurysm is a rare occurrence mainly affecting vessels in the head and neck region, especially the superficial temporal artery, which is a branch of the internal maxillary artery. Most of the time, these aneurysms are secondary to trauma to the face, surgical procedures, or infections. The best imaging modality is angiography; however, alternative less-invasive imaging such as CT angiogram is also helpful in establishing the diagnosis and treatment. Most patients are asymptomatic; however, few patients will need surgical intervention and/or embolization to prevent bleeding as a complication.
