Spiral CT in diagnosis of ovarian teratoma


Of CT. (2) tumor calcification, teeth or bones are important signs of this disease like a. More than a single point, film, cable, and nodules showed that most nodules located on the head rest on the wall. Nodules are usually the first single, also more in diameter is generally 1.0 ~ 4.5cm, were round or oval,mbt outlet, clear boundaries, an acute angle with the wall into the intersection, head nodular density for liquid or soft tissue often no enhancement, see the printed% of nodules of fat, 45% see calcification or teeth, the first nodules found in 48% to 80% of cases J. CT rare performance: (1) float levy is another relatively specific signs. Fat-like small ball floating in the cyst fluid, the formation of the so-called float sign (MobileG10b-ule) [, this small ball can be moved from a small piece of fat accumulation in the debris, scales or hair fat group formed around a small ball to scattered in the shape of certain tumors in vivo. (2) The density of pure water cystic, with or without wall calcification. Zhu Xiang _8J so that the capsule no fat density, but the shadow wall calcification or teeth, still prompt the diagnosis of cystic teratoma. One case the edge of a huge tumor shows fat density less flaky, mistaken for mesenteric fat and misdiagnosed. Fat content of the positioning error is also a misdiagnosis, that the edge of the fat capsule in the capsule film positioned outside or extracapsular fat shadow attributed to capsule. (3) ovarian mature cystic teratoma of 0.25% to 2% may be malignant,> 40 years of age have a high malignancy rate [, head nodule is malignant transformation of a good site,franklin marshall greece, Buy_6J so that the diameter> 5cm in real of head nodules, significantly strengthen and obtuse angle with the wall into the intersection, the growth of the capsule, the surrounding fat layer between the disappearance of organ systems such as signs of malignant transformation. (4) reported in the literature _35J rupture of mature cystic teratoma, a rare tumor to reverse the incidence rate of 10em,canada goose norge, were missed, a retrospective analysis of patients, mainly wall thickening and moderate enhancement, edge blur,nike store outlet, the organizational structure of the surrounding space exudate,Ralph Lauren España, if combined with clinical symptoms and signs generally difficult to diagnose.
