Corioangioma en paciente multípara. Caso clínico / Chorioangioma in multiparous aged. Clinical case

Resumen ANTECEDENTES: El corioangioma es un tumor vascular de origen placentario perteneciente al grupo de los hemangiomas vasculares. Es el tumor placentario primario no trofoblástico más frecuente de origen vascular. CASO CLÍNICO: Paciente de 37 años con antecedentes de: menarquia a los 12 años, inicio de la vida sexual activa a los 13 años, tres embarazos y dos partos. Del embarazo actual solo había tenido dos consultas prenatales. El ultrasonido reportó 35 semanas de embarazo con feto de 2250 g. La paciente tuvo dolor de origen obstétrico y trabajo de parto en fase latente. El parto fue eutócico, sin complicaciones. Se observó una tumoración placentaria. CONCLUSIONES: La valoración placentaria mediante ultrasonido-Doppler de control es importante para detectar tumoraciones y evitar que, cuando son pequeñas, pasen inadvertidas, como los corioangiomas.

Abstract BACKGROUND: Chorioangioma is a vascular tumor of placental origin belonging to the group of vascular hemangiomas. It is the most frequent non-trophoblastic primary placental tumor of vascular origin. CLINICAL CASE: 37-year-old patient with a history of: menarche at 12 years of age, beginning of active sexual life at 13 years of age, three pregnancies and two deliveries. She had only had two prenatal visits for the current pregnancy. The ultrasound reported 35 weeks of pregnancy with a 2250 g fetus. The patient had pain of obstetric origin and labor in the latent phase. The delivery was euthecological, without complications. A placental tumor was noted. CONCLUSIONS: Placental assessment by control ultrasound-Doppler is important to detect tumors and to avoid that, when they are small, they go unnoticed, such as chorangiomas.

Hidrops fetal una complicacion de coriangioma placentario gigante: presentación de un caso y revisión de la literatura / Fetal hydrops, a complication of placental gigant chorioangioma: case presentation and literature review

El corioangioma gigante es el tumor benigno placentario más frecuente, tienen una prevalencia estimada que varía de uno de cada 9000 a 50 000 embarazos.1 Se consideran de gran tamaño cuando son mayores de 5 cm y se relacionan con mayor frecuencia a complicaciones maternofetales como anemia fetal, polihidramnios, insuficiencia cardiaca fetal, hidrops, restricción del crecimiento intrauterino (RCIU), parto pretérmino y un aumento de la morbimortalidad perinatal. Un diagnóstico precoz permite mejorar los resultados perinatales realizando un estricto seguimiento, así como los tratamientos que estén indicados, cuando aparezcan dichas complicaciones.

Giant chorioangioma is the most frequent placental benign tumor, with an estimated prevalence or one in 9,000 to 50,000 pregnancies. They are considered large when they are larger than 5 cm and are more frequently associated with maternal-fetal complications such as fetal anemia, polyhydramnios, fetal heart failure, hydrops, intrauterine growth restriction (IUGR), preterm delivery and an increase in perinatal morbidity and mortality. An early diagnosis allows to improve the perinatal results by carrying out a strict follow-up, as well as establishing the indicated treatments, when these complications appear.

Corioangioma placentario gigante: a propósito del primer caso sometido a fetoscopia y fotocoagulación láser en el Perú / Giant placental chorangioma: Apropos of the first case treated by fetoscopy and laser photocoagulation in Peru

Placental chorioangioma is a non-trophoblastic benign tumor of rare presentation. It may be associated with complications of pregnancy when larger than 4 cm. We present the case of a pregnant adolescent with 25 weeks of gestation referred for prenatal management of a giant placental chorangioma that complicated pregnancy with hydramnios and severe fetal anemia. Fetoscopic laser ablation of the main nutrient vessel of the tumor was performed for the first time in Peru, which reversed complications and improved fetal prognosis.

El corioangioma placentario es una tumoración benigna no trofoblástica de muy rara presentación. Se asocia a complicaciones del embarazo cuando tiene dimensiones mayores a 4 cm. Se presenta el caso de una gestante adolescente de 25 semanas referida a nuestro servicio para manejo prenatal de un corioangioma placentario gigante que complicó el embarazo con polihidramnios y anemia fetal severa. Se realizó por primera vez en el Perú la ablación láser del vaso nutricio principal de la tumoración por fetoscopia, lo que logró revertir las complicaciones y mejorar el pronóstico fetal.

Corioangioma gigante de la placenta con buenos resultados perinatales / Giant Placenta Chorioangioma with Good Perinatal Outcomes

El corioangioma fue descrito por primera vez en 1798 por Clarke. Este es un tumor no trofoblástico de la placenta, constituye una entidad poco usual y se reporta en 1 por ciento de las placentas examinadas microscópicamente, con evidencia clínica en aproximadamente 1:3 500 a 1:9 000 nacimientos. Presentamos el caso de una paciente de 21 años, con una historia obstétrica de embarazos 2, abortos 1, que es valorada en servicio de emergencias con embarazo a término con corioangioma gigante de la placenta. El ultrasonido muestra una imagen redondeada hipoecogénica que se interpreta como: cotiledón placentario aberrante. Se le realizó cesárea y se observa una tumoración redondeada en borde placentario con presencia de una red vascular evidente en su superficie. El ultrasonido es el medio que más favorece el diagnóstico, sobre todo el Doppler. La detección precoz y oportuna de esta afección permite la vigilancia fetal y la prevención de las complicaciones(AU)

Clarke first described Chorioangioma in 1798. This is a placenta non-trophoblastic tumor; it is an unusual entity and is reported in 1 percent of the placentas examined microscopically, with clinical evidence in approximately 1: 3 500 to 1: 9 000 births. We present the case of a 21-year-old patient, with an obstetric history of two pregnancies and one abortions, who is evaluated in emergency services with full-term pregnancy with giant placenta chorioangioma. Ultrasound shows a rounded hypoechoic image that is interpreted as aberrant placental cotyledon. A caesarean section was performed and a rounded tumor was observed on the placental border with the presence of an evident vascular network on the surface. Ultrasound is the way that most favors diagnosis, especially Doppler. Early and timely detection of this condition allows fetal monitoring and prevention of complications(AU)

Corioangioma placentario gigante. Reporte de un caso / Giant placental chorioangioma. A case report

Resumen Antecedentes: El corioangioma es el tumor placentario benigno más frecuente (1%). Cuando miden más de 5 cm pueden causar complicaciones materno-fetales, por lo que es importante establecer el diagnóstico prenatal. Caso clínico: Paciente de 25 años, atendida en el Hospital Español de Beneficencia de Pachuca, con fetometría de 19.2 semanas, acorde con el ultrasonido del primer trimestre. En la evaluación del estudio de imagen se observó edema craneal; área cardiacatorácica 0.55 (anormal), compatible con cardiomegalia severa. El ultrasonido Doppler materno mostró la placenta en localización anterior y una tumoración de 7.53 x 6.74 x 6.33 cm, con zonas hiper e hipoecoicas, que protruía la superficie fetal de la placenta, arriba de la inserción del cordón umbilical. Los vasos de alimentación con diámetro máximo de 3 mm, ubicados superficialmente y cerca de la inserción del cordón. En la valoración del ultrasonido Doppler fetal: ACM-PVS: 33.5 cm/s, 1.37 MoM, anemia leve y DV IP 1.02 (> p95 anormal); en la vena umbilical del cordón se observó flujo pulsátil, pool máximo de 5.81 cc y longitud cervical de 4 cm. Mientras se integraba un equipo multidisciplinario se acordó tratamiento expectante hasta el nacimiento; debido a las repercusiones hemodinámicas el feto falleció. El estudio histopatológico confirmó el diagnóstico de corioangioma (hemangioma placentario), de 7 cm de diámetro mayor. Conclusiones: Es importante reportar los casos de corioangioma placentario, con la finalidad de contribuir al conocimiento y estimar las tasas de morbilidad y mortalidad materno-fetal.

Abstract Background: Chorioangioma is the most common benign placental tumour (1%). If these are greater than 5 cm, it can cause various maternal-fetal complications, so it is important to perform your prenatal diagnosis. Clinical case: Female patient of 25 years-old, attended at the Hospital Español de Beneficencia de Pachuca with suggestive diagnosis with fetus of 19.2 weeks, according to the ultrasound of the first trimester; in the imaging study cranial oedema was observed; cardiac-thoracic area 0.55 (abnormal), compatible with severe cardiomegaly. The maternal Doppler ultrasound showed the placenta in the anterior location and tumour of 7.53 x 6.74 x 6.33 cm, with hyperechoic and hypoechoic zones, which protruded the fetal surface of the placenta, above the insertion of the umbilical cord; the feeding vessels with a maximum diameter of 3 mm, located superficially and close to the insertion of the cord. In the evaluation of fetal Doppler ultrasound: ACM-PVS: 33.5 cm/s, 1.37 MoM, mild anaemia and DV IP 1.02 (> p95 abnormal); In the cord umbilical vein pulsatile flow was observed, maximum pool of 5.81 cc and cervical length of 4 cm. While a multidisciplinary team was formed, expectant treatment was agreed upon until birth; however, soon after, the fetus died due to hemodynamic repercussions. The histopathological study confirmed the diagnosis of chorioangioma (placental hemangioma), 7 cm in greatest diameter. Conclusions: It is important to report the cases of placental chorioangioma, with the purpose of contributing with the knowledge and estimating maternal-fetal morbidity and mortality rates.

Quistes subamnióticos en el contexto de restricción de crecimiento fetal / Subamniotic cysts in the context of growth restriction fetal

RESUMEN La restricción de crecimiento fetal (RCF) es el término con el que se define a aquellos fetos que no alcanzan el potencial de crecimiento intraútero esperado debido a factores genéticos o ambientales. Dentro de las causas de RCF asociadas a la placenta encontramos mosaicismo confinado a la misma, enfermedad isquémica placentaria y anomalías estructurales a este nivel. Se presenta el caso de una paciente de 32 años con diagnóstico de RCF que asocia múltiples quistes econegativos subamnióticos en la cara fetal de la placenta. Se finaliza la gestación en semana 34 mediante cesárea electiva por ausencia de diástole en el estudio Doppler de la arteria umbilical, evidenciando cinco quistes subamnióticos de 4 a 6 cm que alteran la superficie del amnios.

ABSTRACT Fetal growth restriction (FGR) is the term used to define those fetuses that do not reach the expected intrauterine growth potential due to genetic or environmental conditions. The causes of FGR associated with the placenta are confined placental mosaicism, placental ischemic disease and placental structural abnormalities. We report a case of a 32-year-old patient with a diagnosis of FGR associated with multiple subamniotic econegative cysts overlaying the fetal plate of the placenta. The gestation is ended in week 34 by elective cesarean section due to absence of diastolic flow in the umbil-ical artery, showing five subamniotic cysts from 4 to 6 cm that disrupt the surface of the amnion.

Spontaneous necrosis of a giant placental chorioangioma: case report / Necrose espontânea de um corioangioma placentário gigante: relato de caso

Chorioangiomas are the most common benign placental tumors, with an estimated prevalence of 1%. Whilst small chorioangiomas usually remain asymptomatic and are of no clinical significance, larger tumors (>4cm) can be associated with a variety of complications, ranging from fetal anemia to in-utero demise in up to 40% of cases. Despite size being a major determinant for the risk of complications, the degree of the chorioangioma's vascularity also seems to play a role. In fact, in selected cases, occluding the tumors vessels (e.g. with alcoholic instillation) appears to improve the prognosis due to the subsequent tumor ischemia. We present the case of a 40-year-old woman who at 29 weeks was found to have a large placental hypervascular mass (93mm×66mm) and polyhydramnios, with an elevated peak systolic volume in the middle cerebral artery. She was given corticosteroids for fetal lung maturation, and throughout her admission both the volume of amniotic fluid stabilized and the peak systolic volume in the middle cerebral artery normalized, with changing of the ultrasonographic characteristics of the chorioangioma, with apparent progressive necrosis. At 34 weeks, a large subchorionic hematoma was found and, due to the risk of impending placental abruption, we opted to deliver by cesarean section, with a favorable outcome.(AU)

Corioangiomas são os tumores placentários benignos mais comuns, com uma prevalência estimada de 1%. Embora pequenos corioangiomas geralmente permaneçam assintomáticos e não tenham significância clínica, tumores maiores (> 4cm) podem estar associados a diversas complicações, que variam de anemia fetal até a morte intraútero em até 40% dos casos. Ainda que o tamanho do tumor seja um determinante principal para o risco de complicações, o grau da vascularidade do corioangioma também parece desempenhar um papel importante. De fato, em casos selecionados, a oclusão dos vasos tumorais (por exemplo, através de instilação de álcool) parece melhorar o prognóstico devido à subsequente isquemia tumoral. Apresentamos o caso de uma mulher de 40 anos a qual, com 29 semanas de gestação, apresentava grande massa hipervascular placentária (93×66mm) e poli-hidrâmnio, com elevação do peak systolic volume in the middle cerebral artery. Ela recebeu corticosteroides para a estimulação da maturação pulmonar fetal e durante a sua internação o volume de líquido amniótico foi estabilizado e o peak systolic volume in the middle cerebral artery normalizado, com mudança nas características ultrassonográficas do corioangioma, com necrose progressiva aparente. Com 34 semanas de gestação, observou-se a presença de hematoma subcoriônico de grande porte e, devido ao risco de descolamento prematuro da placenta, optou-se por parto cesariano, com desfecho favorável.(AU)

Corioan gioma placentario gigante: Reporte de caso / Giant plancental chorioangioma: case report

Los corioangiomas placentarios son tumores vasculares benignos y los tumores placentarios más comunes, con una prevalencia de 1%. Raras veces sobrepasan los 4 a 5 centímetros y, cuando esto ocurre, es descrito como corioangioma gigante. Los embarazos con corioangiomas gigantes están asociados con complicaciones maternas y fetales, tales como anemia hemolítica microangiopática severa, parto pretérmino, polihidramnios, restricción del crecimiento intrauterino del feto, trombocitopenia e hidropesía. Se presenta un caso de un corioangioma gigante diagnosticado a las 22 semanas. A pesar del seguimiento estricto, el parto se produjo a las 30 semanas debido a polihidramnios y rotura prematura de membranas. Tanto la madre como el recién nacido se recuperaron sin complicaciones.

Placental chorioangiomas are benign vascular tumors and are the most common placental tumors, with a prevalence of 1%. It rarely surpasses 4 - 5 centimeters in length and, when it happens, is referred to as giant chorioangioma. Pregnancies with giant chorioangiomas are associated with maternal and fetal complications, such as severe microangiopathic haemolytic anemia, preterm labor, polyhidramnios, intrauterine growth restriction, thrombocytopenia and hydrops. A case of giant chorioangioma diagnosed at 22 weeks is presented. Despite close follow-up, delivery occurred at 30 weeks of pregnancy due to polyhidramnios and premature rupture of membranes. Both mother and newborn recovered without complications.
