Prenatal rhabdomyomas. Case report

Abstract

Introduction: Primary cardiac tumors are rare in childhood and mostly benign, being the most common rhabdomyomas, associating more than 60 % of patients with tuberous sclerosis. Most of them tend to regress, but some, depending on their location and clinical manifestations, require surgical treatment. Regardless of its benign character (it is considered a hamartoma and not a true neoplasm), their tendency sometimes to obstruction of tracts input or output, and heart Arrhythmogenesis, makes prognosis that is uncertain. Case report: pregnant 25.5 weeks of gestation with a history of previous health than in fetal echocardiography several cardiac tumors are identified in the left ventricle, septum and interventricular larger tumor in left ventricular (LV) outflow tract obstructing this. The case had followed for Clinical genetics for Rhabdomyoma obstructing the RV outflow tract. The patient decided the abortion and the diagnosis were confirmed by pathological examination. Conclusions: Fetal cardiac tumors are extremely rare. You can be diagnosed by ultrasound from intrauterine life. The recommended attitude is expectant about the possibility of spontaneous regression, except in cases with clinical impact. In the follow-up should rule out the presence of tuberous sclerosis because of its high association with this entity.
