我们描述一个病人与单侧唾液腺扩张的Stensen导管。X线涎腺造影、MR涎腺造影和超声检查显示腮腺刺激期间Stensen管多发性狭窄和念珠状扩张。刺激前，磁共振涎腺造影和超声检查显示Stensen管局灶性扩张。患者还患有同侧咬肌肥大（BMH），这可能是导致唾液腺扩张的原因。
We describe a patient with unilateral sialectasia of Stensen's duct. X-ray sialography, MR sialography, and ultrasonography showed multiple stenoses and rosary dilatation of Stensen's duct during stimulation of the parotid gland. Before stimulation, Stensen's duct showed focal dilatation as indicated by MR sialography and ultrasonography. The patient also had ipsilateral masseter hypertrophy (BMH), which may be a cause of sialectasia.
