This report describes the color and pulsed Doppler US findings of penile 
Mondor's disease. The pulsed Doppler US findings of penile Mondor's disease have 
not been previously published, so we report here for the first time on the 
cavernosal arterial flow signal pattern of penile Mondor's disease. Penile 
Mondor's disease is rare disease that's characterized by thrombosis in the 
dorsal vein of the penis. The previous reports on penile Mondor's disease are 
concerned with the color Doppler US finding without the flow signals in this 
area, but these findings are insufficient to understand the hemodynamics in 
penile Mondor's disease. We report for the first time on a cavernosal artery 
flow signal pattern of low peak systolic velocity and high-resistance.
