A 77-year-old woman presented with a pulsatile blue-tinged mass over the left parotid, present for 5 years, and slowly enlarging. The size of the mass fluctuated during this period and there was no associated pain. The patient reported no history of surgery or trauma. Vascular lesions are rarely encountered within parotid glands in adults. MRI with contrast demonstrated a soft tissue lesion; despite the presence of feeding vessels it was thought unlikely to be an arterial venous malformation or aneurysmal change. The appearance was thought to be in keeping with an enlarged lymph node or sebaceous cyst. Fine-needle aspiration was obtained using ultrasound guidance and yielded bloody fluid. The lesion was closely related to the superficial temporal artery and a diagnosis of a thrombosed pseudoaneurysm was made. The vessel had thrombosed and the decision was made to enact a watchful waiting policy. The patient will be monitored in the outpatient setting.
一名77岁女性，左侧腮腺处有一个搏动性、带蓝色调的肿块，已存在5年，且在缓慢增大。在此期间，肿块大小有波动，无相关疼痛。患者无手术或外伤史。成人腮腺内很少遇到血管病变。增强磁共振成像显示一个软组织病变；尽管有供血血管，但认为不太可能是动静脉畸形或动脉瘤样改变。其表现被认为与肿大的淋巴结或皮脂腺囊肿相符。在超声引导下进行细针穿刺，抽出了血性液体。该病变与颞浅动脉关系密切，诊断为血栓形成的假性动脉瘤。血管已形成血栓，决定采取密切观察策略。患者将在门诊接受监测。
