I found a hemangioma cyst in the liver since 2007 by CT scan. I had monitored the cyst by ultrasound every year during medical check up. The 2cm cyst seem not to have any progress in size during the past 4 yrs, until today check up my ultra sound result show an increase in size. It grows to be 3cm. I try to figure out what would cause this and being very suspicious on my minor stroke treatment during the yr. I had taken Plavix for 2mon. Just wondering if there could be an effect of this to the in crease in size of my hemangioma?
