Highly vascularized left atrial myxoma mimicking a cardiac haemangioma: a case report
Abstract
Background: Primary cardiac tumours are rare; atrial myxomas predominate, while haemangiomas 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 haemangioma.
Discussion: Hypervascularity cannot reliably distinguish myxomas from haemangiomas. Although multimodal imaging is important for surgical planning, definitive diagnosis relies strictly on histopathological evaluation.
