Disappearing intracardiac thrombi in both atria after mumps in a patient with Turner syndrome.

A girl with Turner syndrome was admitted with an acute cerebrovascular occlusive disease 15 days after mumps infection. Imaging techniques such as Doppler echocardiography, computed tomography and angiography of the heart revealed the existence of masses in both atria. Eight days after the last radiologic study the patient had an operation, but no masses were found in either atrium. It was thought that atrial thrombi, probably formed after viral infection, had broken down to form emboli and disappeared. It is proposed that the patients with congenital cardiopathy should be regularly examined after viral infections for possible intracardiac thrombus formation. If such a mass is found and the decision is to operate, the existence of the mass must be confirmed even in the operating room just before intervention.
