Papillary fibroelastomas are benign masses often originating from the endocardium of the aortic and mitral valves. Rarely, these neoplasms are found in areas of the heart embryonically distinct from the aortic and mitral valves. Diagnosis of a papillary fibroelastoma relies on multimodal imaging as well as histologic assessment. A case series of papillary fibroelastomas in unusual locations is presented, highlighting the role of multimodal imaging techniques in identifying these intra-cardiac masses. Differential diagnoses, imaging characteristics, histopathology, and preferred management strategies for cardiac masses are reviewed. The unique imaging qualities of cardiac masses are discussed.
乳头状纤维弹性瘤是一种良性肿块，通常起源于主动脉瓣和二尖瓣的心内膜。这些肿瘤很少发生在与主动脉瓣和二尖瓣胚胎起源不同的心脏区域。乳头状纤维弹性瘤的诊断依赖于多模态成像以及组织学评估。本文呈现了一组罕见部位的乳头状纤维弹性瘤病例，重点介绍了多模态成像技术在识别这些心内肿块中的作用。本文还回顾了心脏肿块的鉴别诊断、影像学特征、组织病理学和首选管理策略。讨论了心脏肿块的独特影像学特征。
