I found out this morning that one of my co-workers who I worked closely with in OB had surgery yesterday at Cleveland Clinic due to a Cavernous Malformation. This is basically a cluster of blood vessels that looks like a bunch of berries on her brain. The lesion can cause headaches, nausea/vomiting, visual disturbance, and seizures. Surgery is the only treatment available. I am praying for minimal "side-effects" from this surgery for her.
