嗅裂区呼吸道上皮腺瘤样错构瘤的影像分析

Imaging analysis of respiratory epithelial adenomatoid hamartoma of olfactory clefts

目的:分析嗅裂区呼吸道上皮腺瘤样错构瘤(REAH)的影像学特点,为临床的诊断和治疗提供依据。方法:收集经病理证实的54例鼻腔嗅裂区REAH患者资料,分析其影像学特点。结果:所有患者病变均位于双侧嗅区,鼻窦CT及MR示双侧鼻腔嗅区可见软组织呈膨胀性生长,将双侧中鼻甲向外侧挤压,形成"蘑菇头"样改变。所有患者伴有不同程度的鼻窦炎或鼻息肉。结论:REAH有独特的影像学表现,跟鼻息肉有区别。临床医师如能充分认识该病,术中彻底切除嗅区病变,可以提高治愈率,降低术后复发率。

Objective：Analyze the imaging features of respiratory epithelial adenomatoid hamartoma（REAH）of olfactory clefts,to provide the basis for clinical diagnosis and treatment.Method：A retrospective study of 54 cases of nasal REAH of bilateral olfactory clefts confirmed by pathology were collected,analyze their imaging information.Result：All the lesions of 54 cases are located in olfactory cleft,sinus CT and MR show soft tissue shadows in olfactory cleft which grows expansive,extruding bilateral middle turbinate to the lateral sides,and it＇s like ＂the head of mushroom＂.All the cases are with different degree of sinusitis and nasal polyps.Conclusion：This kind of REAH has special imaging performance,and it＇s different from nasal polyp.So if clinical doctors can fully recognize this disease and completely resect the lesion of olfactory cleft in operation,we can increase the probability of treatment,and reduce the probability of postoperative recurrence.
