“…More often, these cysts are incidental findings after birth on chest radiography, cardiac ultrasound, magnetic resonance imaging (MRI) and computerized tomography (CT). There is a wide spectrum of pathology, encompassing mesothelial‐derived pericardial and pleural cysts, bronchogenic cysts, esophageal duplication cysts, neurenteric cysts, and cysts of other origin9–11. The long‐term prognosis of congenital cystic lesions appears to be good in many cases, but potentially life‐threatening complications related to rupture or compression of adjacent tissue structures and vessels may occur12–20.…”

Fetal echocardiography enables early detection of paracardial cyst. Pericardial cysts disappeared spontaneously during the course of gestation without signs of fetal cardiac compromise, suggesting a benign prognosis. Imaging by magnetic resonance and computerized tomography were particularly useful to clarify the etiology, structure and extent of those cysts that had not resolved by the time of birth.

“…Congenital thymic cysts result from the degeneration of aberrant thymic tissue after the arrest of thymic primordium migration along the thymopharyngeal tract 1 . Although congenital thymic cysts can occur anywhere from the neck to the mediastinum, most are in the neck 2 …”

“…To our knowledge, 2 cases of fetal thymic cysts have been reported prenatally. Those cases did not need any additional intervention in utero because one cyst did not produce a mass effect, 6 and the other did not change in size until delivery 2 . There is no consensus on the in utero obstetric management of thymic cysts and which delivery mode is better because most are detected postnatally.…”

Fetal mediastinal teratomas represent only 10% of congenital teratomas in children and 2.6% of all mediastinal masses in children. Teratomas have multifactorial etiology, such as chromosomal abnormalities. Fetal mediastinal teratomas are rare. Mediastinal teratomas can cause hydrops fetalis, fetal demise, and neonatal respiratory distress; therefore, accurate perinatal management and interventions are very important. We describe a case of fetal mediastinal teratoma wherein the cystic fluid in the fetal tumor was aspirated and confirmed by surgical pathology after birth at the authors' center. The teratoma in this case was characterized by a large single cystic mass with clear borders in the anterosuperior mediastinum, which grew rapidly and was closely related to the thymus. The infant was healthy at birth, and the tumor was surgically removed the age of 1 year. The postoperative course was uneventful, and the patient was in good health 6 years postoperatively. This case and literature review suggests that ultrasound examination can accurately diagnose fetal mediastinal teratomas, which is beneficial to provide an accurate basis for fetal prenatal intervention and treatment. Additionally, an important ultrasound feature of a fetal unicystic mediastinal teratoma is a saddle‐shaped mass with clear boundaries, which provided an accurate reference for the diagnosis of a fetal cystic mediastinal teratoma by prenatal ultrasonography.
