Acevedo, J. A., Caballero, J. G., Lencinas, A., Córdoba, M., & Pesquín, M. (2021). We report the case of a 73-year- old female patient with vomiting, aspiration pneumonia and constitutional symptoms. The imaging tests showed total gastric herniation in the pericardial sac through a pericardio-peritoneal window previously created. The case was solved with surgery. The therapeutic options for persistent pericardial effusion are considered. Intrapericardial gastric hernia as a complication, its clinical presentation, intraoperative findings, complementary tests and treatment are discussed.
