.68 Ct Signs In Patients With Orbital Tumors Analyzed

OBJECTIVERetrospective analysis of various epibulbar Computer Tomography scan images of the characteristics of orbital tumors diagnosis, differential diagnosis, and provides the basis.METHODSChoose from that Computer Tomography scan of sixty-eight cases of orbital tumors clinically histologic confirmation by Medical School Affiliated Hospital of Qingdao University clinical pathology from 2002 to 2010 were retrospctively analyzed.According to the classification, such as orbital cyst, vascular tumor, neurogenic tumor, non-specific inflammation, lacrimal tumor, malignant lymphoma.Different parameters as the lesion location, shape, border, relationship with surrounding tissure, calcification in orbital tumors were summarized.The character of compuer tomography imaging of different kinds of tumors was reviewed and compared.Paper summarizes the research analysis of tumor computer tomography characteristics.RESULTSComputer Tomography imaging characteristics of benign tumors had clear borders, round high density, and a clear demarcation between the surrounding tissue, CT value 28.1; Malignant tumors of irregular forms, density of not even, with the surrounding tissue boundary is not clear, and many have orbital wall bone destruction, calcified plaque, CT value 46.71. Common signs for sixteen Computer Tomography in turn for:the eye muscle pull shift proof, after the ball in muscle cone round sites, bone sag, lachrymal area sites, optic nerve, orbit for the coarse pointed triangle area, tumor transparent in liquefaction, tracks calcified plaque signs, etc.CONCLUSION1. Through the Computer Tomography images of 68 cases of orbital tumor, summarize sixteen common signs of Computer Tomography images:after the ball in muscle cone sites, lachrymal area sites, bone defection, orbit pointed triangle transparent area, vein stone, dumbbell sign, casting samples for signs, tracks sign, calcification, takes bone sag, compression deformation of eye, tumors internal change, the optic nerve coarse, the eye muscle infiltrating the rough drafts, the eye muscle push press on shift.2. According to the sum of Computer Tomography signs, rapid, accurate positioning of the tumour, qualitative diagnosis, improve the clinical preoperative diagnosis accuracy, to guide the surgery and evaluation prognosis has certain significance.
