Children of NPC and misdiagnosis of imaging


See this group of pathology report histological type of poorly differentiated and undifferentiated cell carcinoma more common, may be related to the environment, soil and other relevant regional differences: divergence to be further explored Misdiagnosis 3.2 (1) lack of knowledge: Some doctors believe that NPC patients, mostly adults, age of onset is 30 to 50 years old, have significant regional and familial, southern high incidence of common diseases in this group than for the 514-year-old children, low incidence areas are the north, no significant familial and regional, with yellow Fujinami reports the same: some professional knowledge and diagnosis by the physician-dimensional limit, its incidence is not enough understanding of the law, lack of clinical experience. Emphasis on diagnosis and treatment of local symptoms of the profession, as well as parents of children of neglect or lack of understanding, resulting in missed or misdiagnosed. In this group the first provincial specialist misdiagnosis rate of 8.3%, while the county the following first diagnosis physician misdiagnosis rate as high as 96.7%, because in addition to their lack of knowledge and professional restrictions, with some children do not with the examination, a small number of physician examination or inspection techniques are not carefully control, lack of relevant imaging or pathology related = (2) occult lesions, atypical signs and symptoms: nasopharyngeal nasopharyngeal recess is a good site, location deep, near the complex, diverse clinical manifestations. Because children nasopharynx large normal variation, no obvious symptoms of early disease, early detection is difficult to properly assess and invasion of adjacent structures ~ j Sishi, many of diseases related to clinical symptoms, cavernous sinus syndrome, jugular fossa syndrome, Horner syndrome and cranial nerve damage and other symptoms of a cervical lymph node to many more children with tuberculosis, angioneurotic headache, otitis media and sinusitis treatment,nike free run, not taking into account the NPC or the NPC due to violation of adjacent structures, failure to carry out related checks, causing some delay in diagnosis in children in the primary hospital, subject to inspection of equipment limitations, the lack of relevant images, clinical examination and pathological examination,moncler outlet, leading to missed or misdiagnosed: 3.3 precautionary measures (1) increase Children's understanding of nasopharyngeal carcinoma: nasopharyngeal symptoms as children hidden, clinical manifestations, the primary hospital non-specialists, especially children, pediatricians must be familiar with the clinical features of nasopharyngeal carcinoma, careful history taking, especially on the neck mass, refractory headache, sinusitis and otitis media in children with symptoms such as treatment, taking into account the possibility of nasopharyngeal carcinoma: a comprehensive examination not only carefully, but also for nasopharyngeal CT or MRI, clinical examination and pathological Some scholars believe that checks a 31: No matter what disease treatment should be done with nasopharyngeal examination paper argues that: nasopharyngeal fiber-optic endoscopy, visual field brightness, observed a wide range, especially after the nose is generally not observed to the site, limited mild bleeding and mucous membranes of the rough surface of inequality, has a unique advantage, if the following symptoms should be held in nasopharyngeal Society for microscopic examination and biopsy: ① painless neck lymph nodes. ② retraction of the blood, tears, or tears in the blood or persistent increase in nasal congestion: ③ refractory or recurrent earache, tinnitus and hearing loss ① unexplained refractory headache (2) the combination of clinical and laboratory examinations : As to the surrounding nasopharyngeal carcinoma often violated,abercrombie fitch paris, such as the eustachian tube, pterygopalatine fossa, cavernous sinus and brain and other parts, there may be cavernous sinus syndrome, jugular fossa syndrome,moncler danmark, Horner syndrome, nerve damage and skull base and other symptoms in some patients with eye pain, diplopia or strabismus, and vision loss and other symptoms misdiagnosed as optic neuritis or glaucoma cT and MRI in the diagnosis of nasopharyngeal carcinoma is an important and indispensable tool that can clearly show the site of lesion, morphology, size and scope of violations of adjacent structures, to determine the stage and of great value to determine the treatment, some scholars believe that: the incidence of nasopharyngeal infection with EB virus closely related to EB virus infection in children, the relationship between the incidence of more significant than in adults. In particular,moncler paris, VCA-lgA and EA-lgA combination of two antibodies, and clinical, nasopharyngoscopy, CT, MR / pathological and comprehensive analysis, the diagnosis of nasopharyngeal carcinoma in children is more reliable store of value, is to avoid misdiagnosis mistake important measures of governance:
