目的探讨上颌窦炎性假瘤的临床病理学、放射学特点及诊断治疗方法。方法对我科收治的2例上颌窦炎性假瘤患者的临床资料进行回顾性分析。结果上颌窦炎性假瘤患者临床表现及影像学检查酷似恶性肿瘤,行鼻内镜下手术治疗和术腔放置局部类固醇激素明胶海绵,术后口服强的松药物治疗,预后良好。结论上颌窦炎性假瘤需依据病理学检查确诊,熟悉其临床表现及影像学表现,避免误诊、误治。
Objective To investigate the clinical pathology, radiological features and diagnosis and treatment of inflammatory pseudotumor of maxillary sinus. Methods The clinical data of 2 patients with maxillary sinusitis pseudotumor treated in our department were analyzed retrospectively. Results The clinical manifestations and imaging findings of patients with inflammatory pseudotumor of maxillary sinus resembled malignant tumors. Surgical treatment of endoscopic sinus surgery and placement of topical steroid gelatin sponge in the surgical cavity were performed. Postoperative oral prednisone treatment showed good prognosis. Conclusion The maxillary sinus inflammatory pseudotumor should be diagnosed by pathological examination, familiar with its clinical manifestations and imaging findings, to avoid misdiagnosis and mistreatment.
