Double trouble--a case report of mobile right atrial thrombus in the setting of acute pulmonary thromboembolism.

We report the case of a 51 year-old woman who, six weeks post hysterectomy, developed an acute on chronic pulmonary thromboembolism. On transthoracic echocardiography a mobile right atrial thrombus was detected at the entry of the coronary sinus into the right atrium. A 64 slice spiral CT angiogram confirmed the left sided superior vena cava and bilateral extensive thrombus in the proximal pulmonary arteries.
