Left Atrial Myxoma Infected With Fusobacterium Nucleatum

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.
