Abstract
Primary cardiac tumors are very rare, with a reported incidence of 0.15% to 0.2% in autopsy series. They can be life threatening because of myocardial compression and ventricular dysfunction. Once diagnosed during pregnancy, the clinical condition of the baby is monitored because of the risk of rupture of the tumor capsule. The authors report a rare case of a neonate who presented with respiratory and cardiac compromise due to cardiac tamponade necessitating emergency exploration of the pericardium and excision of tumor. A well-encapsulated tumor measuring around 5 cm and bigger than the heart was completely excised. This was diagnosed to be an immature teratoma. Follow-up echocardiogram was normal, and on serial monitoring, alpha-fetoprotein was within normal limits. The baby was discharged home with no complications. Intrapericardial teratoma in neonates is a surgical emergency if presented with significant pericardial effusion. It can be a challenge if diagnosed in utero with rupture before the viability of pregnancy. A multidisciplinary team approach is necessary to manage such situations. Complete excision is necessary because of its association with tissues of malignant potential.
