鼻部复发性多形性腺瘤一例及文献复习

Recurrent Pleomorphic Adenoma of the Nose:A Case Report and Review of Literature

探讨鼻部复发性多形性腺瘤的临床病理特点、影像学表现及鉴别诊断。回顾性分析1例鼻部复发性多形性腺瘤的病例资料,结合相关文献进行学习。患者表现为鼻塞及左眼溢泪,副鼻窦MRI表现为左侧鼻腔内软组织肿块,其内信号混杂,边缘清,鼻腔肿物切除术后病理诊断为多形性腺瘤。术后随访4年,因视物模糊、鼻出血再次入院,CT表现为边界清、密度均匀的软组织肿块,MRI示肿块内部信号不均匀,增强扫描明显不均匀强化,术后病理诊断为多形性腺瘤复发。多形性腺瘤在术后易复发,因此术前通过影像学检查准确诊断该疾病,可以提醒术者选择合理的手术方式,扩大肿块切除范围,降低术后复发率。

To investigate the clinicopathological features,imaging features and differential diagnosis of recurrent pleomorphic adenoma of the nose.To analyzed the data of a case of recurrent pleomorphic adenoma of the nose and review related literatures.The patient presented with nasal obstruction and lacrimal discharge in the left eye,and MRI of paranasal sinus showed a soft tissue mass in the left nasal cavity,with mixed internal signals and clear margins.After resection of nasal mass,the patient was pathologically disgnosed as pleomorphic adenoma.During the follow-up for 4 years,the patient was readmitted to the hospital due to blurred vision and epistaxis.CT showed a soft tissue mass with clear boundary and uniform density,MRI showed uneven internal signal of the mass and obvious uneven enhancement on enhanced scan.The postoperative pathological diagnosis was recurrence of pleomorphic adenoma.Pleomorphic adenoma is prone to recurrence after surgery.Therefore,accurate diagnosis of this disease through preoperative imaging examination can remind the surgeon to choose a reasonable surgical method,expand the tumor resection scope and reduce the postoperative recurrence rate.
