Cisto pericárdico mesotelial simples numa localização rara

© 2016 Sociedade Portuguesa de Cardiologia. Published by Elsevier España, S.L.U.Pericardial cysts are rare and generally benign intrathoracic lesions, most frequently located in the cardiophrenic angles, but other locations have been described. We present a case of a pericardial cyst in a previously undescribed site. Our patient presented with a cyst in the interventricular septum which was discovered as an incidental finding. After surgical excision of the cyst, it was described pathologically as a simple mesothelial pericardial cyst. The explanation of this rare condition is uncertain, but some hypotheses can be outlined.info:eu-repo/semantics/publishedVersio
