Mature cystic teratoma of anterior mediastinum in a 4-month-old infant: a rare case report

A giant teratoma in the anterior mediastinum found prenatally: A case report

“…Therefore, teratomas in infants and even neonates are relatively rarely found. In 2020, Senai et al ( 3 ) reported on a case of a 3-month-old child with anterior mediastinal teratoma, considering this to be the youngest case reported in Uganda. Fetal mediastinal teratomas can be detected using prenatal ultrasound and can cause fetal hydrops.…”

“…AFP concentration is increased in children with germ cell tumors and is of great significance in the diagnosis ( 3 ), treatment, and follow-up of malignant teratomas. However, in the neonatal period, there is a physiological increase in AFP, with levels being generally higher than 2,000 ng/ml.…”

“…In clinical diagnosis, the signs and symptoms of neonates with anterior mediastinal teratomas are often not characteristic. Prenatal color Doppler ultrasound can detect fetal anterior mediastinal tumors; postnatal cardiac ultrasonography can determine the cystic and solid nature of the tumor; and enhanced computed tomography (CT) can clearly show the density, calcification, and other tumor characteristics, as these are essential to diagnose teratoma ( 3 ). In clinical treatment, complete tumor resection is the best solution, and the prognosis of this disease is satisfactory, with a high long-term survival rate.…”
