心脏肿块并不常见，但对心脏病学实践仍具有重要性，因为它们可能通过梗阻和心律失常症状给患者的生命带来破坏。这些病变主要包括瓣膜脓肿、血栓和肿瘤。粘液瘤是最常见的原发性心脏肿瘤，主要起源于左心室。从右侧心脏瓣膜中出现粘液瘤极为罕见。标准治疗是通过手术切除，无论大小，但这并非总是可行的。我们报告了一个独特的男性病例，患者伴有多种共病，被诊断为偶然发现的肺动脉瓣肿块，有粘液瘤的嫌疑。粘液瘤瘤块无症状，没有右心室出口道阻塞。超声心动图可帮助识别和表征这些病变，但这并不容易，特别是在病变的位置和形态不典型的情况下。同样，在一些病例中，患者可能无法接受手术切除。在这种情况下，没有定论或指南可以帮助临床医师更好地进行医学管理，从而形成诊断和治疗上的困境。Copyright © 2023, Khan et al.

Cardiac masses are not common but remain important in cardiology practice as they can cause havoc to a patient's life through obstructive and arrhythmogenic symptoms. These lesions mostly include vegetation, thrombi, and tumors. Myxomas are the most common primary cardiac tumor, primarily arising from the left heart chambers. It is exceedingly rare for a myxoma to emerge from the right-sided cardiac valves. The standard treatment is surgical resection, regardless of size, which is not always possible. We report a unique case of a male with multiple co-morbidities who presented with an incidental finding of a pulmonary valve mass suspicious of being a myxoma. The myxomatous mass was asymptomatic with no right ventricular outflow tract obstruction. Echocardiogram can help identify and characterize these lesions, but this may not be easy, especially in the case of atypical location or morphology of the mass. Similarly, in some cases, the patient may not be able to undergo surgical excision. In such cases, there is no consensus or guidelines to help clinicians best manage the patients medically, creating a diagnostic and therapeutic dilemma.Copyright © 2023, Khan et al.
