Cardiac neoplasms are a rare finding of which a cardiac myxoma is the most commonly encountered. Therefore, a density identified in the left atrium commonly leads to the presumptive diagnosis of an atrial myxoma. However, other pathologies, such as atrial thrombi, can mimic in clinical presentation and appearance to a myxoma. Clinically, these pathologies may lead to obstructive symptoms such as syncope, palpitations, or sudden cardiac death. At present, echocardiography, magnetic resonance imaging, or computed tomography can be used to identify such masses, but fall short of identifying the primary cause. The management of atrial thrombi is not yet fully understood and definite recommendations have not been established. We present a case of an 87-year-old man complaining of syncopal episodes found to be secondary to an incidental intracardiac density resulting from age-related amyloidosis.
心脏肿瘤是一种罕见的发现，其中心脏黏液瘤是最常见的。因此，在左心房发现的密度通常会导致心房黏液瘤的推定诊断。然而，其他病变，如心房血栓，在临床表现和外观上可能与黏液瘤相似。临床上，这些病变可能导致阻塞性症状，如晕厥、心悸或心源性猝死。目前，超声心动图、磁共振成像或计算机断层扫描可用于识别此类肿块，但无法确定其主要病因。心房血栓的治疗尚未完全明确，也未确立明确的建议。我们报告一例87岁男性，因年龄相关性淀粉样变性导致心脏内偶然发现的密度而出现晕厥发作。
