Sturge-Weber syndrome is a rare disorder that is present at birth (congenital), characterized mainly by a congenital facial birthmark and neurological abnormalities. Other symptoms can include eye and internal organ irregularities. Each case of Sturge-Weber Syndrome is unique and exhibits the characterizing findings to varying degrees, so two patients coming with this condition will pretty much present different features. The facial birthmark or "Port Wine Stain" present at birth and typically involving at least one upper eyelid and the forehead. Neurological concerns relate to the development of excessive blood vessel growth on the surface of the brain (angiomas). These are located typically on the back (occipital) region of the brain on the same side as the port wine birthmark. These angiomas create abnormal conditions for brain function in the region.This photo here clearly shows leptomeningeal angiomas on the young girl's right occipital and temporal lobes.
