<unk>  occurs at a critical location, which makes this tumor extremely deathly and not operable in newborn children. One of the leading equipments that can be used for diagnosing teratoma and<unk>  is ultrasound. The picture that the ultrasound generates is a sonogram, and the evaluation is called sonography. Diagnosis of<unk>  may be made before the birth of the child with ultrasound. Sonography evaluation is essential during pregnancy for diagnosing it and perhaps surgically removing the teratoma while the child is not born yet. One of the main characteristics of<unk>  in the sonography evaluation is a relatively large mass that can be seen in the anterior or front side of the neck. For diagnosing<unk> , radiographing, which is an imaging tool for bones and skeleton, might not be very helpful because no skeletal abnormalities were seen in several cases. However, microscopic examination of the tumor might be helpful. The microscopic examination focuses on the cell growth pattern. Because<unk>  is a type of teratoma, they have a unique structure to their cell growth. Hence, the pattern of microscopic examination can show a growth pattern consistent with teratoma. The other method that can be used to diagnose<unk>  is karyotyping, which shows abnormalities in the fetus. However, the parents' chromosomes are healthy, and there is no evidence of it being inherited genetically. Epiganthus is a very rare condition that makes the studies on it more of case studies. In some of these case reports, it was seen that the diagnosis of<unk>  occurred as early as 17 weeks. However, in other case studies, the ultrasound was normal at 17 weeks. These abnormalities were found after 16–17 weeks, which can illustrate that the teratoma may form later in pregnancy. If the tumor is small enough, it might appear at the delivery unpredicted or even later on, in a child. For example, in one case,<unk>  was detected at week 28, which caused change in the structure of face and airways, and the child was born in week 34 with Caesarean section and needed assistance for breathing. If the diagnosis of<unk>  does not happen during pregnancy, and the baby survives to birth, even though it becomes immediately apparent, there is a low chance for survival. Other clinical features include dyspnoea, cyanosis, and difficulty in breathing, sucking and swallowing due to the presence of the tumor.
