Nearly thirty talks and posters were presented. When tumors occur in young people, they are more likely caused by a hereditary condition. On the last day, Dr. Neumann summarized the recommendations of the symposium regarding cerebellar hemangioblastomas. Screening is done with MRI with gadolinium. They can grow fairly large without symptoms.
Early diagnosis is important to prevent loss of function.
There was interest in the possible contribution of radiosurgery for cerebellar hemangioblastoma. Dr. Hsia noted that it is important to screen VHL women before childbearing because of the tendency of tumors to grow at a faster pace during pregnancy. Dr. Dieter Schmidt of Freiburg summarized the recommendations for retinal angiomas. He screens the retina with contact glass and fluorescein angiography as needed, in an effort to find lesions when they are very small. He treats angiomas with laser, especially small ones in the periphery, treating them in multiple sessions to avoid blistering the retina.
