Cardiac blood cysts are rare benign neoplasms, usually involving the cardiac valves and are remnants of the Chiari network. They are usually detected in the first six months of life and rarely occur in children or adults. We report a 76-year-old male patient who was referred to the Imam Ali Hospital affiliated with Kermanshah University of Medical Sciences, Kermanshah, Iran, in 2018 with dyspnoea. Transthoracic echocardiography revealed a small patent (PFO) and a circumferential mobile cystic mass in the right atrium, with the impression of a tumour or thrombus. The patient underwent open-heart surgery with cardiopulmonary bypass to repair to PFO and remove the intra-atrial lesion. During surgical examination of the right atrial cavity, a blood cyst containing small stone-like structures on the coronary sinus valve of the right atrium was found. The post-operative course was uneventful and no recurrence of tumour was detected during six months of follow-up. To the best of our knowledge, this is the first reported case of a right atrial blood cyst with a few nodule-like stones in an adult with PFO in Iran and the second case in an adult with PFO worldwide.
心脏血囊肿是一种罕见的良性肿瘤，通常累及心脏瓣膜，是奇静脉瓣遗迹。它们通常在出生后的头六个月被发现，很少发生于儿童或成人。我们报告一例76岁男性患者，2018年因呼吸困难转诊至伊朗克尔曼沙赫医科大学附属伊玛目阿里医院。经胸超声心动图显示一个小型卵圆孔未闭（PFO）以及右心房内一个环形可移动的囊性肿物，考虑为肿瘤或血栓。患者接受了体外循环下的心内直视手术，以修复卵圆孔未闭并切除心房内病变。在对右心房腔进行手术检查时，发现右心房冠状窦瓣上有一个含有小结石样结构的血囊肿。术后过程顺利，在六个月的随访中未发现肿瘤复发。据我们所知，这是伊朗首例报告的成年卵圆孔未闭患者出现的伴有一些结节样结石的右心房血囊肿病例，也是全球第二例成年卵圆孔未闭患者出现该病例。
