Teratoma of the fetal neck is the most common benign tumor, cystic, solid or solid cystic origin. It consists of tissues, the structure of which is strikingly different from those that are around the tumor. Such neoplasms, the location of which is the front and back triangle of the neck, is commonly called cervical teratomas of the neck.
Causes of a tumor of this species
In view of the fact that studies of the fetal teratoma, as well as the factors that provoke it, are absent, which was affected by the rarity of the appearance of children with this diagnosis, there were no precise reasons for the appearance of the tumor. The available samples show that the development of abnormal formations can be caused by the displacement of the thyroid tissues of the child and their fusion with the capsule of the teratoma. In any case, the tumor is formed at the initial stage of fetal cell division, and particles of any organ or system of the child can get into it.
Diagnosis of a fetal teratoma
Identification of this education is possible with the help of a standard apparatus of ultrasound. Often, the diagnosis is made by chance, on the next scheduled visit to the doctor. As a rule, the terato can be detected starting from the 19-20 week of gestation, after which the tumor begins to grow intensively. Its dimensions can reach more than 12 centimeters in diameter, which facilitates rapid detection.
Pregnancy and teratoma: what are the predictions?
In order to establish the correct tactics of behavior, it is necessary to decide whether the vital structures or organs are involved in the terat. There is information that education can equally lead to the birth of a dead child, and to the safe treatment of a baby after childbirth. However, if the tumor still touched the organs important for the normal existence, then it is only a lethal outcome for the fetus. The mortality rate among children sent after delivery for the operation is about 37-50%, whereas the number of dead but not operated babies reaches 80-100%. The reasons explaining such monstrous indicators are the connection of the tumor and its close placement with vital vessels and organs, as well as obstruction of the upper respiratory tract.
Treatment of teratoma
A favorable outcome of the resolution of the burden of a baby with such a diagnosis means that he will have to survive the inevitable surgical intervention, the absence of which will lead to imminent death. The scope of the future operation and its complexity directly depend on the size of the tumor, the state of the child's health, the exact location of the teratoma and the presence of any more complications. During the intervention, surgical suction is repeatedly required to pump out the fluid that has accumulated inside the tumor.
The sacrococcygeal teratoma of the fetus
Tumor of this species is more often found in female children. It is a collection of cysts and neoplasms filled with serous fluid or mucoid substance. As a rule, this pathology is found on the 6th to 9th month of gestation.
Concomitant phenomena can be: deformation of internal organs, kidney diseases, fetal edema , abundance of amniotic fluid and birth before the term.
It is quite possible to perform a prenatal puncture of a teratoma of this type, if its structure is predominantly cystic. In this case, under the supervision of ultrasound apparatus, the tumor is punctured and the fluid is sucked from it. In the future it is necessary to wait for the ripening of the lungs and to insist on deliveries of the previously established time.
