Acute renal infarction in a patient with left atrial myxoma.

A 24-year-old male first attended our hospital with acute onset of right flank pain radiating to the right lower quadrant of the abdomen. A contrast-enhanced computer tomography (CT) scan showed renal infarction, and he was admitted immediately for treatment. On admission, the right lower abdominal pain diminished gradually. On the second day in hospital, a left atrial echogenic mass was detected which filled the left atrial cavity; it appeared to be a left atrial myxoma measuring 3.9 ± 4.9 cm. The patient was immediately transferred and underwent emergency surgery. Histologic examination confirmed the diagnosis of myxoma. Post-operatively, he recovered well and was discharged from hospital without any further specific treatment.
