Conclusion:
Surgical resection remains the treatment of choice for intrapericardial
teratomas. During anaesthetic management, one should anticipate
cardiopulmonary collapse upon induction, particularly with non-intubated
patient with severe mass effect, as well as hemodynamic instability
associated with blood loss and tumor manipulation. Understanding the
potential complications associated with intrapericardial teratomas was
paramount in the successful anaesthetic management of our patient.
