Successful surgical management of a prenatally diagnosed intrapericardial teratoma

Congenital intrapericardial teratoma is a rare, usually benign tumour frequently associated with massive pericardial effusion, cardiac compression, and severe cardiorespiratory distress shortly after birth. Surgical removal is not only curative but also potentially lifesaving because these lesions often become fatal if not promptly excised. We present a case of a newborn with a huge intrapericardial teratoma diagnosed in utero. After normal delivery the infant underwent surgical removal and has had clinical follow-up for more than 11 months.

In utero diagnosis of intrapericardial teratoma: a case forin utero open fetal surgery

We present a case of intrapericardial teratoma diagnosed by ultrasound at 26 weeks of gestation presenting as a large tumour mass and rapid development of hydrops fetalis. The fetus died in utero one day before scheduled open fetal surgery.

Intrapericardial teratoma in an adult: A rare presentation

Background Intrapericardial teratomas are rare and usually present early in infancy or childhood. Procedure We describe herein a rare case of an adult patient with an intrapericardial teratoma who presented with fever, cardiac arrhythmias, and oppressive substernal chest pain. Preoperative diagnosis was suggested by echocardiography and computerized tomography of the chest. The tumor weighed 530 g and its histologic features were those of a mature cystic teratoma. It was excised totally and 10 years' follow-up revealed no evidence of residual disease. Discussion Our patient is one of the very few adult patients with intrapericardial teratomas who was treated successfully with surgery. Both echocardiography and tomography of the chest suggested the diagnosis and delineated the relationship of the tumor to the great vessels. Conclusion The diagnosis of Intrapericardial teratomas is suspected by echocardiography and/or tomography of the chest and confirmed by specific histologic features. These tumors should be excised whenever detected. Med. Pediatr. Oncol. 30:249–251, 1998. © 1998 Wiley-Liss, Inc.

Surgical management of intrapericardial teratoma diagnosed in utero

Intrapericardial teratoma is a rare, often benign congenital tumor, which frequently leads to respiratory distress and pericardial tamponade shortly after birth. Surgical excision is not only curative but potentially lifesaving, because these lesions often become fatal if not promptly excised. We present a case of one of two twins diagnosed with a large intrapericardial teratoma. The management of this case was complicated by the necessity to consider the well-being of the other (normal) twin in planning the timing of delivery and operation. After the twins were delivered by cesarean section in one operating room, the mass was excised from the infant in an adjoining operating room with cardiopulmonary bypass standby.

Intrapericardial teratoma in a twin fetus: Diagnosis and management

A rare cause of hydrops fetalis, intrapericardial teratoma is invariably associated with a pericardial effusion. In fetal life, the effusion or mass effect may cause cardiac tamponade, hydrops, and death. After delivery, ventilation and cardiac output may be compromised. One fetus of twins was diagnosed at 20 weeks' gestation with an intrapericardial teratoma. The affected twin underwent two intrauterine pericardiocentesis and had the tumor resected after delivery at 35 weeks' gestation. One year later, both twins are alive and well and have no evidence of tumor recurrence. Pericardiocentesis for tamponade secondary to a fetal intrapericardial teratoma, even when complicating a twin pregnancy, may prevent fetal death and allow delay of delivery until adequate fetal lung maturity has been achieved.

Intrapericardial Teratoma in the Newborn Without Pericardial Effusion and literature Review. 165

An intrapericardial teratoma is a rare tumor but it is the second most common cardiac tumor of childhood after rhabdomyosarcoma. A search of literature from 1966 until 1994 revealed 57 cases. Pericardial effusion is thought to be a hallmark of intrapericardial teratoma. We present a baby boy born at 38 weeks gestation that was diagnosed prenatally to have a mediastinal mass but its intrapericardial location was not diagnosed until surgery due to absence of pericardial effusion. After birth the baby was in respiratory distress and patient was operated the next day and subsequently discharged home in good condition. The pathology report showed a well encapsulated cystic structure measuring 4.5×4×2.2 cm. The cyst wall thickness varied from 0.5 to 0.8 cm. Microscopic examination showed a variety of well differentiated mature tissue derived from all three germ cell layers.

Diagnóstico e tratamento cirúrgico do teratoma intrapericárdico

Descrevemos 2 casos de teratoma intrapericardico, tumor cardiaco primario raro, usualmente encontrado em neonatos e lactentes e que pode causar insuficiencia respiratoria, grande acumulo de liquido pericardico e compressao cardiaca, levando a morte no periodo intra-uterino ou neonatal. Em ambos os casos, o diagnostico foi estabelecido pelo ecocardiograma realizado em crianca de 3 meses com sinais de tamponamento cardiaco e no feto de uma gestante no curso da 38o semana de gravidez. Resseccao cirurgica com sucesso em ambos os pacientes foi realizada nas idades de 3 meses e 3 dias de vida, respectivamente. A histologia confirmou o diagnostico de teratoma. Enfatiza-se a acuracia do diagnostico ecocardiografico nestes casos e a importância da indicacao cirurgica precoce.

Non‐immunological hydrops fetalis and intrapericardial teratoma: Case report and review

A large intrapericardial teratoma was found at necropsy in a 38-week stillborn fetus, in which prenatal diagnosis of hydrops fetalis and an echogenic cardiac mass had been made. Clinical and pathological data are reported. In utero intrapericardial teratomata lead to different outcomes depending on whether fetal hydrops is associated. When generalized fetal hydrops is not present, the outcome is good, even in cases with large pericardial effusions. When generalized fetal hydrops occurs, it often results in a poor outcome. In our literature review, we have found eight perinatal deaths in nine similar cases reported.

Early sonographic diagnosis of intrapericardial teratoma.

An intrapericardial teratoma associated with a large pleural effusion and elevated aortic outflow velocity was diagnosed at 23.6 weeks' gestation. Less than 4 weeks earlier, an obstetric scan, including a four-chamber heart view, had been normal. In less than a week following diagnosis, fetal hydrops and bradycardia developed. 'Heroic' pericardiocentesis was declined by the patient, and the fetus died. This case demonstrates the potential for rapid growth in pericardial teratomas, and illustrates the possibility of anticipating fetal compromise from tumor mass effect, when intracardiac Doppler studies are abnormal. Implications for management of these rare tumors, and specifically for the hypothetical role of fetal surgery, are discussed.

Intrapericardial teratoma presenting as recurrent cardiac tamponade in a neonate

A 28-day-old child presented with recurrent cardiac tamponade. Diagnostic tests revealed an intrapericardial tumour but was not conclusive as to the aetiology. The tumour was successfully resected.

Prenatal diagnosis of intrapericardial teratoma

A case of intrapericardial teratoma diagnosed by ultrasound before birth is described. Planning for delivery and immediate neonatal intensive management allowed successful cardiac surgery, full resection of the tumour and full recovery.

Cardiac-compressing intrapericardial teratoma at birth

Intrapericardial teratomas are rare and generally seen in infants and young children. 1–10 They may cause respiratory distress, pericardial effusion and cardiac compression. Several case reports have described children with this neoplasm in whom operative excision was life saving. 5–7,9 We present a stillborn infant with a massive intrapericardial teratoma that caused fatal cardiac compression. Its occurrence in a stillborn has been previously reported only once. 10

Intrapericardial Teratoma in a Newborn: A Case Report

Abstract lntrapericardial teratomas are unusual tumors that often cause respiratory distress and might be lethal in the newborn. The purpose of this article is to present the clinical and pathological findings in a 12‐day‐old male successfully treated for a big intrapericardial teratoma. Given that the diameter of this tumor is generally related to the age at the time of diagnosis, the rarity of our case is the presence of a huge intrapericardial teratoma in a newborn. The surgical resection was lifesaving.
