Cavernous Malformation Symptoms, Causes and Treatment News

What is Cavernous Malformation? (Definition)

(Symptoms, Causes & Treatment)

According to Massachusetts General Hospital, Cavernous malformations (including cavernous angiomas, cavernomas, cavernous hemangiomas) are well-defined, grossly visible lesions that may reach a significant size. They are composed of a compact mass of sinusoidal-type vessels immediately in apposition to each other without any recognizable intervening neural parenchyma.

Cavernous malformations account for an estimated 8-15 percent of all intracranial and spinal vascular malformations.

According to the American Association of Neurological Surgeons, people with a cavernous malformation may experience no symptoms. However when symptoms do occur, they often are related to the location of the malformation and the strength of the malformation walls. The type of neurological deficit is associated with the area of the brain or spinal cord that the cavernous malformation affects. Symptoms may appear and subside as the cavernous malformation changes in size due to bleeding and reabsorption of blood. Any of the following symptoms may occur:

  • Seizures
  • Weakness in arms or legs
  • Vision problems
  • Balance problems
  • Memory and attention problems
  • Headaches
