Highly vascularized left atrial myxoma mimicking a cardiac hemangioma: a case report
Saúl Pérez Barrios, Juan Manuel Aragón González, Henry Noel Fajardo Perdomo, Felipe Rodríguez Mora, Antonio González CalleAbstract
Background
Primary cardiac tumors are rare; atrial myxomas predominate, while hemangiomas represent only 1%–2.8%. Differentiating them is challenging when hypervascular features overlap.
Case Summary
An 81-year-old woman presented with a large, hypervascular left atrial mass supplied by the circumflex artery. Following uneventful surgical resection, histopathology confirmed a cardiac myxoma despite imaging suggesting a hemangioma.
Discussion
Hypervascularity cannot reliably distinguish myxomas from hemangiomas. Although multimodal imaging is important for surgical planning, definitive diagnosis relies strictly on histopathological evaluation.
