BACKGROUND Cardiac myxomas are generally considered benign, but malignant tumors have been reported. Vascular endothelial growth factor (VEGF), an angiogenic factor, plays a role in the growth, progression, and metastasis of solid tumors and it has been reported that VEGF expression is upregulated in cardiac myxomas that have a high microvessel density. The purpose of this study was to determin...

A 67-year-old male was diagnosed as myxoma-related cerebral aneurysm. Transthoracic echocardiogram showed a large mass in the left atrium and pathological analysis confirmed the diagnosis of myxoma. Cerebral magnetic resonance angiography revealed an aneurysm in the right internal carotid artery. However, the aneurysm was disappeared amazingly after successful resection of cardiac mass. There a...

A second recurrence of an excised nonfamilial cardiac myxoma is rare. Myxomatous cerebral aneurysms as a complication of cardiac myxomas are equally rare. A unique case of a patient with a total of 4 myxomas over a 20-year interval is presented. Her most recent presentation was a second recurrence of a left atrial myxoma, a de novo right atrial myxoma, and multiple cerebral myxomatous aneurysms...

Introduction: Cardiac tumors constitute only 0.2% of all tumors. Primary cardiac tumors occur infrequently with an incidence of 0.0017% to 0.19%, estimated on autopsies performed in non-selected populations. Left atrial myxomas are the most prevalent (75% to 80%) and right atrial are less common (10% to 18%). Surgical excision yields an excellent prognosis and recurrence rate of only 3% with a ...

A 55-year-old man with massive pulmonary thromboembolism underwent thrombolysis, pulmonary artery embolectomy and tricuspid annuloplasty. Nine months later, a mobile echogenic intra-cardiac mass was found in the tricuspid valve. Because the patient had undergone annuloplasty, thrombosis was suspected as the most likely diagnosis and thrombolytic therapy was instituted. However, the size of the ...

BACKGROUND Myxoma is a very rare benign cardiac tumor in dogs. This is the first description of a cardiac myxoma originating from the left ventricular outflow tract, presumably causing sudden death. CASE PRESENTATION A previously healthy 12-year-old male West Highland white terrier was found dead during its 1-week stay in a kennel. The dog was known to have a cardiac murmur. On necropsy, a pe...
