Abstract：
In this case report, we present a 23-year-old patient with complaints of a recurrent plop sound in the left ear. Non-contrast CT and MR imaging revealed an enlargement of the tympanic segment of the facial canal due to venous congestion. A persistent stapedial artery (PSA) and absent foramen spinosum were identified as concomitant factors. This unique combination of anomalies has not been previously reported and knowledge about this condition is essential to avoid unnecessary surgery.
UNASSIGNED: A persistent stapedial artery may be associated with enlargement of the tympanic facial nerve canal due to venous congestion.

摘要：
在这个案例报告中,我们介绍了一名23岁的患者，他抱怨左耳反复出现扑通声。非造影CT和MR成像显示，由于静脉充血，面管的鼓段增大。持续的骨动脉（PSA）和棘孔缺失被确定为伴随因素。这种独特的异常组合以前没有报道过，关于这种情况的知识对于避免不必要的手术至关重要。
■由于静脉充血，持续的钉骨动脉可能与鼓室面神经管扩大有关。
