Although necrotizing sialometaplasia (NS) of the parotid gland is rare and occasionally presents as a lesion that mimics a malignant tumour, imaging findings in cases of NS have been rarely reported. We describe here a case of NS in which there was an increasing lesion manifesting overnight on the parotid gland in an 83-year-old male. We also investigated the use of pre-operative imaging based on previous reports and discuss the importance of these images in helping to guard against overzealous treatment. It is critically important to closely examine whether there are aspects of NS, such as the present case, in pre-operative MRI findings that can be useful in proper diagnosis and treatment.
尽管腮腺坏死性唾液腺化生（NS）较为罕见，偶尔表现为类似恶性肿瘤的病变，但 NS 的影像学表现鲜有报道。本文报告 1 例 83 岁男性患者，其腮腺内病变于夜间逐渐增大，我们还根据既往报道探讨了术前影像学的应用，并讨论了这些图像在避免过度治疗方面的重要性。仔细检查术前 MRI 结果中是否存在类似于本例的 NS 特征对于正确诊断和治疗至关重要。
