Cardiac myxomas are the most common primary cardiac tumours in adults. Clinical presentation is variable, with few cases of infected myxomas reported in the literature. We describe a rare case of a 63-year-old patient who presented with splenic abscesses and a left atrial mass suggestive of emboligen myxoma. The patient underwent a successful emergency sur- gical excision of the atrial mass followed by splenectomy. Blood cultures were positive for Fusobacterium nucleatum, whereas the histopathological examination of the excised mass confirmed the presence of a myxoma with a marked inflammatory infiltrate. All these findings allowed us to confirm the diagnosis of definite infected myxoma. Some aspects related to the aetiology, diagnosis and management of this entity are discussed.
