The clinical diagnosis is based on the case history and the physical examination which plays a major role in clinical diagnosis. However, in some cases the typical clinical symptoms are equivocal or misleading. Without using the opportunities of diagnostic imaging the accuracy of preoperative appendix diagnosis ranged between 70 and 78%. Consequently the rate of unnecessary laporotomies ranged between 22 and 28%. Since 1986, 13 studies including more than 5,000 patients have been published showing a sensitivity of 85% and a specificity of 96% if the sonographic examination was performed by an experienced examiner. The rate of negative laparotomies could be decreased to 7%, and possible differential diagnoses could be either confirmed or ruled out by using ultrasound technique.

By revealing a characteristic sonomorphology of reactive lymph nodes we would like to contribute to the differential diagnosis of cervical lymph node enlargements. In 81 patients the morphology and the longitudinal/ transverse axis ratio (L/T ratio) of 257 reactively enlarged lymph nodes were examined. Besides 6 false-positive cases the L/T ratio turned out to be a reliable instrument in detecting reactive lymph nodes. Concerning the nodal texture, 89 lymph nodes (34.6%) appeared homogenously. Those lymph nodes which demonstrated a more complex nodal texture could be assigned to three sonomorphological groups: In 134 lymph nodes (52.1%) a centrally located echogenoic line (\"central echogenoic line', CEL) was observed. Its maximal diameter was defined to be maximally up to one third of the lymph node width. In the histological examination this CEL could be identified as a widened hilus with an increased fibrosis. An echogenoic nodal area measuring between one third up to one half of the lymph node width demonstrated histologically a fatty replacement of the hilar tissue. This \"echogenoic hilus reflex' occurred in 28 lymph nodes (10.9%). A nearly complete lipomatous atrophy of the lymph node parenchyma was found in 6 lymph nodes (2.4%) demonstrating a \"central echogenicity' with just a small peripheral, less echogenoic border corresponding to the remaining parenchyma.</p>","PeriodicalId":77035,"journal":{"name":"Bildgebung = Imaging","volume":"63 2","pages":"113-9"},"PeriodicalIF":0.0,"publicationDate":"1996-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19729816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
