Summary
Severe hydrops foetalis (HF) in a fetus was caused by a mediastinal immature teratoma. This tumor compressed the heart and airway, leading to termination of the pregnancy. Early diagnosis is crucial for managing this rare condition.
Area of Science:
- Perinatology
- Pediatric Oncology
- Pathology
Background:
- Hydrops foetalis (HF) is characterized by excessive fluid accumulation in fetal tissues and body cavities.
- While historically linked to immune causes, non-immune etiologies, particularly tumors, are now more prevalent.
- Mediastinal masses can present significant diagnostic and therapeutic challenges in utero.
Observation:
- A case of severe hydrops foetalis was identified at 19 weeks and 6 days gestation.
- The clinical presentation suggested a diaphragmatic hernia, prompting a pregnancy termination.
- Autopsy revealed a mediastinal immature teratoma as the underlying cause.
Findings:
- The immature teratoma was compressing the fetal heart and major airways.
- This compression was the direct cause of the severe hydrops foetalis.
- Histopathological examination confirmed the diagnosis of mediastinal immature teratoma.
Implications:
- This case highlights the importance of considering mediastinal tumors in the differential diagnosis of hydrops foetalis.
- Early detection and characterization of fetal masses are critical for appropriate management and counseling.
- Understanding the link between mediastinal teratomas and hydrops foetalis can inform prognosis and treatment strategies.

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:22Mitral Stenosis I: Introduction
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
