“…After birth, that neonate was transported to the neonatal intensive care unit and successfully underwent surgery. Similarly to our experience, previous investigators have published case reports and results of studies showing that a prenatal diagnosis of oropharyngeal and cervical teratomas is important for planning delivery and providing adequate intrapartum and postnatal resuscitation …”

“…Facial and cervical teratomas are very rare tumors that appear on US as large lobulated facial masses with solid and cystic components. They are associated with high morbidity and mortality rates because of airway obstruction and compression of other structures, polyhydramnios, nonimmune hydrops fetalis, preterm delivery, and rupture‐related complications . In our study, one pregnancy complicated by a fetal oropharyngeal teratoma associated with bilateral ventriculomegaly was terminated.…”

“…Esophageal atresia often leads to polyhydramnios, usually early in the third trimester3. We found some circumstantial evidence in the literature that impediment to swallowing by goiters4, cervical teratomas5–7 or skin abnormalities8 is associated with polyhydramnios. In our case, the lack of any of these abnormalities in the newborn makes it tempting to postulate that the bulky accumulation of cord loops around its neck may have limited the in‐utero ability to swallow amniotic fluid.…”

Acute severe polyhydramnios developing in the third trimester or at term is a rare condition. Although there are many possible fetal or maternal causes for this phenomenon, in the majority of cases a specific etiology cannot be found. We describe our imaging findings and management of a case of severe acute polyhydramnios developing at the 40 th gestational week.A 24-year-old healthy mother of two children was referred to our obstetrics department at 41+2 gestational weeks of her third pregnancy owing to very recent distention of her uterus. Her pregnancy had been uneventful, including a 22-week sonographic anomaly scan. No other screening tests were performed during pregnancy. During a visit for a routine check-up 1 week earlier, a sonogram revealed normal amniotic fluid volume and adequate gross body and breathing movements. Current sonography at admission revealed severe polyhydramnios, reaching an amniotic fluid index of 40 cm. A Doppler examination of the umbilical cord discovered multiple cord loops wrapped around the fetal neck ( Figure 1). A healthy baby was delivered by Cesarean section. The estimated amniotic fluid volume was approximately 2.5 L. The umbilical cord was tightly wrapped three times around the fetal neck, forming a bulk which limited the free movement of the neck, but no strangulation marks were evident around the baby's neck.Third-trimester or term pregnancy acute onset polyhydramnios is rare, usually mild, and not associated with structural defects 1 . However, in the severe polyhydramnios state, in 75% of cases significant fetal abnormalities are found that predominantly involve the central nervous system, gastrointestinal tract, heart and genitourinary tract 2 . Esophageal atresia often leads to polyhydramnios, usually early in the third trimester 3 . We found some circumstantial evidence in the literature that impediment to swallowing by goiters 4 , cervical teratomas 5 -7 or skin abnormalities 8 is associated with polyhydramnios. In our case, the lack of any of these abnormalities in the newborn makes it tempting to postulate that the bulky accumulation of cord loops around its neck may have limited the in-utero ability to swallow amniotic fluid. This in turn could have led to accelerated, late-onset polyhydramnios. We propose that in any case of such sudden and late development of polyhydramnios, the fetal neck area should be scanned by ultrasonography, and the presence of nuchal cord loops should be considered as a possible cause of the polyhydramnios.

“…Debido a que el teratoma nasofaríngeo presenta crecimiento lento (11), el diagnóstico se realiza habitualmente en etapas tardías de la gestación (69 % de los casos se diagnostican durante segundo trimestre de la gestación) (12), a pesar del advenimiento de la ecografía 3D (13) y de la resonancia magnética fetal (14,15). La ecografía 3D permite visualizar la tumoración en modos multiplanares (13); sin embargo, esta modalidad ecográfica es limitada en aquellos casos donde el tumor no presenta protrusión por la cavidad bucal, lo cual no permite su caracterización en superficie. La resonancia magnética cuyo eje central se fundamenta en una mejor comprensión de los planos anatómicos fetales, permite detallar con mayor precisión el grado de compromiso de la vía aérea, del esófago fetal y a descartar o confirmar la presencia de afección intracraneal (16).…”

Objetivos: reportar el caso de una gestante con diagnóstico de feto con teratoma nasofaríngeo inmaduro y realizar una revisión describiendo el pronóstico de esta patología. Materiales y métodos: se reporta el caso de una gestante de 27 años, atendida en la Unidad de Ginecología y Obstétrica de un centro de referencia en Bogotá (Colombia), por hallazgo durante el control prenatal de un feto con evidencia de polihidramnios secundario a teratoma nasofaríngeo. Se realizó una búsqueda bibliográfica en las bases de datos Medline vía PubMed, Scopus, SciELO y ScienceDirect, restringiendo tipo de idioma (inglés y español) y por fecha de publicación (enero de 2001 a enero de 2021). Se incluyeron reportes de caso y series de casos que abarcaran el pronóstico de esta patología. Resultados: la búsqueda recuperó 168 títulos, de los cuales 55 cumplieron con los criterios de inclusión. En total se reportó el resultado perinatal de 58 fetos con diagnóstico de teratoma nasofaríngeo inmaduro detectado en etapa prenatal. En los casos identificados, la mortalidad perinatal fue del 25,4 % y el porcentaje de óbito fue cercano al 3,6 %. Conclusiones: el teratoma nasofaríngeo inmaduro es una patología poco frecuente. La literatura disponible sugiere que el pronóstico fetal depende del grado de compromiso de las estructuras intracraneales y de la posibilidad de resección de la lesión. Se requieren más estudios que evalúen el pronóstico de los fetos con teratoma nasofaríngeo inmaduro.
