Retromandibular venous ectasia is a rare lesion that may imitate a parotid gland mass. Accurate radiological diagnosis prevents unnecessary invasive procedures. We present the case of a 69-year-old male patient presenting a right-sided, painless, compressible parotid region mass, fluctuating in size with head position and Valsalva maneuver. No thrill was palpable on physical examination. Doppler ultrasound demonstrated an anechoic compressible intra-parotid lesion, with luminal color filling, and venous spectral waveform. Contrast-enhanced computed tomography and Magnetic resonance angiography of the neck revealed an ectatic retromandibular vein. The patient was conservatively managed and regularly followed up. No complications occurred. Cervical region venous ectasias are rare and commonly misdiagnosed. They should be considered in the soft neck masses differential diagnosis. Imaging plays a key diagnostic role.
下颌后静脉扩张是一种罕见的病变，可能会模仿腮腺肿块。准确的放射学诊断可避免不必要的侵入性操作。我们报告一例69岁男性患者，其右侧腮腺区出现无痛性、可压缩肿块，大小随头部位置和瓦尔萨尔瓦动作而波动。体格检查未触及震颤。多普勒超声显示腮腺内有一个无回声、可压缩的病变，管腔内有彩色血流充盈及静脉频谱波形。颈部增强计算机断层扫描和磁共振血管造影显示下颌后静脉扩张。该患者接受了保守治疗并定期随访。未发生并发症。颈部静脉扩张罕见且常被误诊。在颈部软组织肿块的鉴别诊断中应考虑到它们。影像学起着关键的诊断作用。
