DESCRIPTIONA 62-year-old woman was presented to the surgical ward, with severe abdominal pain and vomiting. She had sinus tachycardia (135/min) and her blood pressure was 80/60 mm Hg. The physical examination revealed generalised abdominal distension with signs of peritonitis. Laboratory parameters revealed polymorphonuclear leucocytosis (total leucocyte count of 21 000/mm 3 with 88% neutrophils), blood urea nitrogen=74 mg/dL and serum creatinine=2.1 mg/dL. X-ray of the abdomen showed air under the diaphragm. CT angiography revealed absence of contrast beyond the mid segment of the superior mesenteric artery (SMA) (figure 1). A large filling defect was noted in the left atrium (LA) on CT scan (figure 2). Echocardiogram also demonstrated a large 3.1×3.2 cm rounded, mobile mass in the left atrium, which was heterogeneous in echogenicity ( figure 3A). It was attached to the interatrial septum in the region of the fossa ovalis. The LA appendage was clear ( figure 3B). Neither mitral valve nor left ventricle showed underlying disease.These features were supportive of a diagnosis of cardiac myxoma, instead of a thrombus. Unfortunately, the condition of the patient continued to deteriorate and she succumbed to sepsis. Relatives refused an autopsy, so histopathological
