摘要
目的收集中耳毛状息肉临床病例,总结其影像学特征。方法回顾性分析2007年1月至2020年1月复旦大学附属眼耳鼻喉科医院经手术病理证实的4例中耳毛状息肉患者的临床资料,其中女3例、男1例,左耳2例、右耳2例,年龄1~59岁。分析患者的CT、MRI影像学资料和对应的临床表现。结果中耳毛状息肉蒂部位于鼓室1例,位于咽鼓管骨部2例,表现为无明显诱因的患耳反复流脓;蒂部位于咽鼓管咽口1例,突入鼻咽腔,表现为咽部不适、患侧耳闷,内镜检查见鼻咽腔灰白色息肉状肿物,表面有少许绒毛。4例患者CT、MRI均表现为椭圆形、类椭圆形息肉状软组织团块,壁呈中等密度软组织,内含大量脂肪组织,中央软组织犹如病灶内核,增强后壁及软组织内核强化;MRI显示2例病灶壁内脂肪与软组织夹层状排列。4例患者均行手术治疗,术后病理镜下示鳞状上皮下见毛囊、成熟皮脂腺等皮肤附件,内含大量脂肪组织,部分肌肉组织及软骨组织,部分间质纤维增生,伴胶原变性。结论中耳毛状息肉影像表现具有一定特征性,呈息肉状软组织团块,壁光滑,含大量脂肪组织,中央为软组织内核,CT、MRI可提示毛状息肉的诊断。
Objective To collect the clinical cases of middle ear hairy polyp,and to summarize the imaging features.Methods We retrospectively analyzed the clinical data of four cases middle ear hairy polyp confirmed by surgical and pathologic between January 2007 and January 2020 at the Affiliated Eye&ENT Hospital of Fudan University.There were three females,one male,with two left ears and two right ears,aged from 1 to 59 years.The CT and MRI imaging of the patients,and the corresponding clinical manifestations were analyzed.Results Hairy polyps originated from tympanum in one case,originated from Eustachian tube in two cases,exhibiting recurrent otorrhea without evident inducement.The other case,hairy polyps originated from the Eustachian tube pharyngeal orifice and protruded into the nasopharyngeal cavity,with pharynx discomfort and aural fullness,endoscope showed offwhite polypoid mass with a little hair.All the four cases presented polypoid soft tissue masses on CT and MRI imaging,containing soft tissue wall and a large amount of adipose tissue,with soft tissue in the center of the mass which liked the core,and enhanced.MRI showed stratified arrangement of fat and soft tissue in the wall of the mass.Four cases all had surgical treatment,postoperative pathology examination presented that hair follicles,mature sebaceous glands and other skin appendages were found under squamous epithelium.A large amount of adipose tissue,part of muscle tissue,cartilage tissue,and some fibro-collagenous tissue were proliferated in the mass,accompanied by collagen degeneration.Conclusion The middle ear hairy polyps has imaging characteristics,the polypoid soft tissue mass usually looks smooth and contains a large amount of adipose tissue,with a soft tissue in the center,and can be suggestively diagnosed by CT and MRI.
