Kestle, John R. W. | Natural history of cerebral cavernous malformations | To determine the natural history of brain cavernous malformations, the authors entered patients referred to their center into a prospective registry between 1987 and 1993. All patients underwent magnetic resonance imaging, which showed the typical appearance of this lesion, and conservative manageme... | Cavernous malformation; Vascular malformation; Seizure | 1995 |
