Congenital Thymic Cyst in the Retro Cava Position: A Case Report
نویسندگان
چکیده
INTRODUCTION Congenital thymic cyst (CTC) is a rare mediastinal mass and the retrocaval position of this cyst has not been reported in the medical literature so far. CASE PRESENTATION The present study reports on a 66-year-old female with coronary artery disease (CAD) who was scheduled for coronary artery bypass grafting (CABG) at our hospital. During mediastinal exploration and pericardiotomy for CABG, a large CTC was incidentally found in the retrocaval position, as a watery cyst from its anatomic location and content. Pathological examination revealed that it was a CTC. No cases of retrocaval position of CTC have been reported. Thus, here we report on this case and review the previously reported cases. CONCLUSIONS To our knowledge, this is the first case of CTC that was identified incidentally in the retrocaval position and caused intermittent obstruction of vena cava.
