Ultrasound diagnosis of ovarian teratoma.

Ovarian teratoma is the most common benign tumor in ovarian reproductive cell tumors, and ovarian cystic teratoma, also known as mature cystic teratoma, is a common type of teratoma.
of ovarian teratomas can be formed by 2-3 embryonic tissues, containing skin and its accessories, hair, teeth, nerves, fat, bones, etc.
Benign cystic tumors of the ovaries: characteristics: mostly cystic, sac wall smooth and thin, sac wall uniform smooth, sac wall protruding rules nipples, cystic wall and blood flow is not rich, PI, RI value is high.
mucus cystadenoma: 20% of all tumors in the ovaries, 5% of the evil rate, the vast majority of one-sided, larger tumors, rupture can cause extensive tumor cultivation.
image features: mainly in the shin, from a small amount of shin to a very large amount of shin, is multi-room, the cystic wall and the shin smooth, the liquid turbid, the back wall enhances the effect.
10% visible nipples are called mucusy nipple cystic adenomas.
serous cystadenoma: the most common ovarian tumor, accounting for 27% of ovarian tumors.
mostly benign, but there is a higher tendency to malignant change, about 45%-50% can become malignant.
are often one-sided.
image features: mostly single-room, thin wall, smooth, border clear, less internal echo, internal light band separated into multi-room, rear wall echo enhancement.
the inner wall of the cyst showed that the nipple-like substantial photocall was a nipple-like slurry cystic adenoma.
1 ovarian mature cystic teratoma: common, acoustic images are diverse.
ovarian fibroma (fibroma): a real tumor with unclear cling film, the echo is denser than decay, calcified spots can appear.
called Meg's syndrome when they combine chest and abdominal water.
ovary metastasis tumor, Krukenberg tumor: 80 percent of metastasis tumors.
are often two-sided solid tumors, echo attenuation or reflectivity is strong, common de-sacs, sizes vary.
Ovarian teratoma acoustic map, because of its composition and proportion of different performance, can be expressed as "lipid layering signs," "dough signs," "waterfall signs," "snowflakes signs," "line signs," "wall nods," "messy structural signs" 7 kinds of specific images.
Teratomas with typical acoustic images are easier to diagnose, resulting in misdiagnosis or omission of teratomas mainly occurring in a single tissue composition, the occurrence of such teratomas is low, and ultrasound performance is different from the common teratoma ultrasound characteristics composed of a variety of organizational structures.
need to be identified with ovarian endometriosis cysts, slurry cyst adenomas, simple cysts, etc.
The ultrasound of the ovarian endometriosis cyst is reflected in the dense dot echo within the cyst, but it can also appear in the band-like interval and the clump-shaped slightly higher echo, which can be bonded with the surrounding tissue, the cystic wall is thick and brown, the higher echo is more deposited in the middle and back, flocs, looser, pressurized probe or follow-up visible form changes.
patients generally have a history of menstrual pain.
The fine dot shape of the ovarian teratoma is thinner, denser and higher than that of the endometriosis cyst, and the clump-shaped high echo is denser, more uniform, higher, with clear boundaries and often accompanied by sound shadow.
easily confused with cystic and mixed ovarian teratomas, and it is necessary to be alert to the co-existing conditions of both.
liquid cystic adenoma: single-room or multi-room cystic adenoma boundary is clear, the sac wall is thin and complete, the inner wall is smooth, the slender separation is smooth and uniform.
mastoma protrudes on the inner wall of the sac, and fine striped blood flow can be seen on the sac wall, in-sac space and mastoma.
simple cysts: follicle cysts, jaundial cysts, attachment inflammatory cysts, ovarian coronary cysts, broad ligament cysts, etc., can be commonly referred to as simple cysts.
general internal sound transmission is good, no obvious light point, ultrasound is manifested as a cyst in the annex area next to the palace, thin wall, no echo inside.
ovarian teratoma is shown as no echo in a single-room tumor, the limitation of the cystic wall is visible thickened and the echo is enhanced.
