Guidelines for sites linking to mayoclinic.orgCavernous malformations (cavernomas) are abnormally formed blood vessels that have the appearance of a small mulberry in the brain or spinal cord. The leakage of blood from these malformations may cause significant blood loss (hemorrhage). Cavernous malformations may enlarge slowly as a result of repeated small hemorrhages. Seizures may also occur when the malformation is in the surface layer of the brain (cerebral cortex).
At Mayo Clinic, doctors trained to treat diseases of the brain (neurologists, neuroradiologists and neurosurgeons) and cancers of the brain using radiation (radiation oncologists) work together to diagnose and treat people who have cavernous malformations. This collaboration, along with Mayo Clinic's use of advanced diagnostic tools, enables thorough evaluations.
