Compressive Pericardial Teratoma about a Case at Regional Hospital of Saint Louis/Senegal

Introduction: Cardiac tumors in children are rare.Most are discovered in children under one year of age.Echocardiography is the basic examination for the screening, it allows their detection from the fetal stage.Observation: She was a 14-year-old patient with no known history of pathology.She was admitted to our department for the exploration of dyspnea and chest pain.At her admission, she had stable hemodynamics.At cardiac auscultation, heart sounds were muffled.The EKG recorded a sinus rhythm, and negative T-waves from V1 to V4.The chest X-ray showed cardiomegaly and a dense, rounded, heterogeneous left hilar opacity, well limited.Echocardiography objected to a great intrapericardial mass in front of the left cardiac cavities compressing part of the left atrium and left ventricle associated with an important pericardial effusion.The CT scan found a heterogeneous pericardial suspected myxoma mass.The pathological examination confirmed pericardial teratoma.The patient had an excision of the pericardial mass.The evolution after surgery was favorable.Conclusion: Intra-pericardial teratomas are benign tumor.Complete removal of the tumor is curative and without recurrence.
