Asymptomatic intracardiac thrombus in a child with nephrotic syndrome.

Nephrotic patients are at risk of developing venous and arterial thromboses. Various organ manifestations have been reported. Intracardiac thrombi associated with multiorgan thrombosis have been reported in autopsy in the earlier literature, but there is only one case report in living patients with nephrotic syndrome. Here we report a 9-year-old boy with steroid-resistant nephrotic syndrome who developed an asymptomatic but potentially hazardous large intracardiac thrombus.
