Imaging Studies Of CT And MRI In Nasal Cavity Tumor

Objective：Through the retrospective analysis and sum up the surgical pathologydiagnosed343cases of patients with nasal cavity tumor imaging signs：⑴Improve theimaging examination in the accuracy of qualitative diagnosis in the neoplasm；⑵Clearpositioning,choice of operative methods of imaging examination in nasal preoperativeauxiliary value,so as to guide clinical complete removal of lesion,and maximum keepthe nose structure.Methods：Collected from January2011to July2013in Bethune first hospital ofJilin university and (or) MRI and CT has a total of343patients with definitepathological diagnosis of nasal tumors,185cases of male,158cases of male,agesbetween7and85, the average age is43.5,with269cases benigntumor(78.4%),including nasal polyps for147, nasal inverted papilloma for50, nasalvestibular cyst for25, hemangioma for21, fibroangioma for11,fungal sinusitis for9,neurilemmoma for3, pleomorphic adenoma for1,lipoma for1,week of vascularmuscle skin tumor for1;74cases of malignant tumor (21.6%), including non-hodgkin’slymphoma for23,squamous cell carcinoma for13,adenoid cystic carcinoma8,adenocarcinoma for8,varus papillary adenoma canceration for8,melanoma for3,nasal glioma for2,inflammatory fibroid tumor for1,chondromyxoid fibroma for1,olfactory neuroblastoma for1,rhabdomyosarcoma for1.CT scan in275cases,enhance the33cases,MRI scan in49cases,enhance the41cases.All cases wereconfirmed by surgery pathology,before CT and (MRI) examination were treated withnasal surgery or radiation and chemotherapy.Clinical symptoms mainly for nasal congestion, runny nose (pus stuff, blood cried, epistaxis), dizzy, headache (nasal facialpain),hyposmia or disappear,the nose uplift,some patients withdiplopia,exophthalmos,eye movement disorder and decreased vision and evenblindness.Side,gender,age group,the mass shape,edge,the range of bonechange,growth,growth way,center,basal,density and signal,strengthening thecharacteristics,the sac/necrosis and calcification and bleeding,and statistical analysiswere made based on the correlation of benign and malignant lesion.Results:343cases of nasal cavity tumor patients,the nasal benign tumoraccounted for78.4%,malignant tumors21.6%.The analysis shows that:⑴lump shape,edge, growth mode and scope of necrosis capsule, basement,bone destruction, adjacentstructure involved and MRI reinforcement method and the mass of statisticalsignificance was found between benign and malignant(P<0.05).⑵Mass side, gender,age group,the center of the lesion,CT and MRI scan and degree of reinforcement, CTimproved way,calcification and bleeding no statistical significance between of benignand malignant neoplasm (P>0.05).Conclusion:1.Mass shape, margin, growth mode, growth range,basal,sac/necrosis, bonedestruction,adjacent structure involvement will help determine the nature of the lesion.2.Bump side dont, gender, age group, the center of the lesion site, density, signal,strengthening characteristics,calcification and bleeding to judge the character of masshas no obvious effect.3.To nasal cavity tumor preoperative CT and MRI diagnosis has importantauxiliary qualitative,positioning,help to improve the precision of the surgery,to guideclinical complete removal of lesion,reduce the postoperative recurrence rate,and maximum keep the nasal structure,improve the patients’ long-term quality of life.
