Angiomas are also known as strawberry naevi. These are malformations of blood vessels in which fine arteries and veins combine. They can occur not only in visible places such as on the surface of the skin, but also inside the brain. Generally speaking, angiomas exist from birth, however they can also develop over time and cause symptoms.
Depending on the size and position of the angioma, either mechanical irritation or a lack of oxygen can cause seizures. The changed perfusion of the blood can sometimes lead to visual or speech problems, paralysis or changes in personality. Angiomas can often also cause bleeding in the brain.
Angiomas are generally removed using microsurgery. In some cases, embolisation and/or radio-surgery can also be used.
