原发性心脏肿瘤并不常见，大约 70-80% 被归类为良性。粘液瘤约占所有良性心脏肿瘤的一半，而心脏包虫囊肿则极为罕见。呼吸短促是与这些情况相关的一个突出症状。超声心动图作为主要的诊断工具，可以实现早期发现。首选的治疗方案是手术切除肿块。我们的第一个病例是一名 51 岁女性，因主诉呼吸短促和心悸持续 3 个月而到心脏病门诊就诊。体检和测试均在正常范围内。超声心动图显示右心房粘液瘤大小为 65 * 35 毫米。尽管不影响瓣膜和心室功能，肿块还是被手术切除了。我们的第二个病例是一名 55 岁男性，因反复发烧、呼吸急促和胸痛而入院心脏病科。体格检查和测试均正常。超声心动图显示右心房游离壁上有一个具有间隔外观的回声肿块。该患者被诊断为包虫囊肿，接受了手术切除。我们遇到了两例不同的RA肿块病例，分别是粘液瘤和包虫囊肿，我们进行了相应的处理。右心房粘液瘤通常表现为非特异性呼吸短促，除非它们引起瓣膜阻塞。如果临床结果提示右心房肿块感染，除了初步考虑赘生物外，还必须考虑包虫囊肿作为潜在的诊断。© 2024。作者。

Primary cardiac tumors are uncommon, with approximately 70-80% classified as benign. Myxomas constitute roughly half of all benign cardiac tumors, while cardiac hydatid cysts are exceptionally rare. Shortness of breath is a prominent symptom associated with these conditions. Echocardiography serves as the primary diagnostic tool, enabling early detection. The preferred course of action involves the surgical excision of the mass.Our first case, a 51-year-old female presented to the cardiology outpatient clinic with complaints of shortness of breath and palpitations persisting for 3 months. Physical examination and tests were within normal limits. Echocardiography revealed a right atrial myxoma measuring 65 * 35 mm. Despite not affecting valve and ventricular functions, the mass was surgically resected. Our second case, a 55-year-old male admitted to the cardiology clinic with recurrent fever, shortness of breath, and chest pain. Physical examination and tests were normal. Echocardiography revealed an echogenic mass with a septate appearance adhering to the free wall of the right atrium. The patient, diagnosed with a hydatid cyst, underwent surgical resection.We came across two different cases of RA masses which happened to be myxoma and hydatid cysts, and we managed accordingly. The right atrial myxomas typically present with nonspecific shortness of breath unless they cause valve obstruction. In cases where clinical findings suggest infection in the right atrial masses, it is essential to consider hydatid cyst as a potential diagnosis alongside the initial consideration of vegetation.© 2024.
