Cavernous malformations are abnormal clusters of dilated blood vessels. They may form anywhere in the body, including the brain, spinal cord, and nerves. They vary in size from 2 millimeters to several centimeters, leaking blood in the brain and spinal cord. If left untreated or unnoticed, they may cause serious neurological symptoms.

Cavernous Malformation Symptoms

Some people may have cavernous malformations and not exhibit any symptoms. Symptoms tend to occur once the bleeding has begun. These include: 

  • Seizures
  • Headaches
  • Paralysis
  • Hemorrhage
  • Stroke 

Cavernous Malformation Causes

Most cavernous malformations occur as a single instance and without apparent cause. However, family history may be a contributing risk factor. 

If you’re experiencing any of the above symptoms or want a second opinion, call 727-828-8400.
