No other hemorrhage-associated symptoms, such as abdominal pain, fever, consumptive syndrome, or anemia developed. This means that having a mutation cavernpso one of the two genes present on a chromosome is not enough to cause the cavernous malformation, but mutation of both alleles would cause the malformation. In our first case follow-up of 76 months showed a nongrowing residual tumor and stable medical condition; in the second case, follow-up of 64 months showed a neurologically intact patient without tumoral recurrence on MR images.
