  A cerebral cavernous malformation is an irregularly formed blood vessel, shaped like a small mulberry. It can form in the brain or spinal cord and may result in a wide range of neurological symptoms. […] CCMs may leak blood and lead to bleeding in the brain or spinal cord, known as a hemorrhage. Brain hemorrhages can cause many symptoms, such as seizures. […] Depending on the location, CCMs also can cause stroke-like symptoms such as trouble with movement or feeling in the legs and sometimes the arms. CCMs also may cause bowel and bladder symptoms. […] Cerebral cavernous malformations (CCMs) may not cause symptoms. Sometimes when the CCM occurs on the outer surface of the brain, it can cause seizures. […] Generally, symptoms of CCMs may include: Seizures. Bad headaches. Weakness in the arms or legs. Numbness. Trouble speaking. Poor memory and attention. Trouble balancing and walking. Vision changes, such as double vision.

  Cavernomas are abnormal clusters of vessels with small bubbles (or caverns) filled with blood that make them look like a berry. These can range in size from microscopic up to several inches in diameter. […] While a cavernous angioma may not affect function, it can cause seizures, stroke symptoms, hemorrhages, and headaches. […] We usually only diagnose a cavernoma after you have had a seizure, a loss of function, or a surprise finding when we perform a magnetic resonance imaging scan for another reason. Cavernomas may have no symptoms but about one in three people with cavernous angiomas eventually develop symptoms, often between ages 20 and 40. […] The type, frequency and severity of symptoms often depend on the location of the cavernoma. Typical symptoms include: Headache, Epileptic seizure, Neurological loss, such as Limb weakness, Vision or balance problems, Problems with memory and attention, Brain Hemorrhage, which can be small, but sometimes massive, leading to stroke-like symptoms, Spinal cord injury.

  https://www.ninds.nih.gov/health-information/disorders/cerebral-cavernous-malformations

  Cerebral cavernous malformations (CCMs) are lesions in the brain that can leak blood into the brain and cause symptoms like seizures, headaches, or back pain. Some people with CCMs never have symptoms. Having more, larger CCMs means the person usually will have more symptoms. […] CCMs can leak blood into the brain, which can cause symptoms including: Seizures, Headaches, Back pain, Hearing or vision changes, Paralysis. […] Seizures tend to get worse and happen more often as people with CCMs get older. In rare cases, CCMs bleed into the brain (called a hemorrhage) and cause a stroke that can lead to death. […] Because CCMs can change in size and number over time, people with this disorder usually need lifelong monitoring. Doctors can track CCMs and identify changes over time with regular MRIs.

  When a cavernous malformation leaks, bleeding can be slow and intermittent or rapid, causing sudden symptom onset. Most people who develop neurological deficits after a hemorrhage improve dramatically over time. However, repeated hemorrhages may result in permanent neurological problems. […] Symptoms of a cavernous malformation may include: Seizures, Headaches, Bleeding in the brain (hemorrhage), Hearing or vision changes, Weakness, numbness, or paralysis, Memory deficits, Speech impairment, Unsteadiness. […] These lesions usually are not life-threatening, but repeated bleeds may cause permanent neurological deficits. Malformations in sensitive tissue like the brainstem and thalamus can be extremely disabling if they bleed.

  Cavernous malformations can change in size and number over time and can range from several millimeters to several centimeters in size. […] As many as 40% of people with cavernous malformations in their brains never experience symptoms or receive a diagnosis. Most people in this group have: a single malformation, no family history, no inherited mutation. […] Symptoms vary depending on where the malformation forms. […] Seizures are one of the most common symptoms of cavernous malformations in the brain. Other symptoms can include: headaches, bleeding (hemorrhage), hemorrhagic stroke, slurred speech, double vision, balance problems, tremor, memory problems, poor concentration, limb weakness or numbness.

• #7 Cavernous Malformations | Neurological Surgery

  https://neurosurgery.weillcornell.org/condition/cavernous-malformations

  Cavernous malformation The tangle of capillaries in a cavernous malformation may leak and create small caverns of blood within the brain. […] A cav-mal may remain stable for decades and never cause any symptoms at all. Some people only discover that they have a cavernous malformation when they have an MRI scan for some other reason, such as after a car accident or other injury (an incidental finding). In those individuals, no treatment at all may be needed. […] But a cavernous malformation may begin to leak (hemorrhage) intermittently over the course of months or years. In some people, the cav-mal causes symptoms that get worse with each small hemorrhage, then gradually get better as the leaked blood is reabsorbed, only to worsen again with the next hemorrhage. The malformation usually grows slowly over time, enlarging with each small hemorrhage.

  There is no typical way in which cavernous malformations (also known as cavernous angioma or cavernoma) affect people. The symptoms, the course of the illness, and its severity can be very different from person to person. […] The rarest place for a symptomatic cavernous malformation is in the spinal cord. A spinal cord cavernous malformation is not the same as a spinal hemangioma, which is located in the vertebra (bone). Cavernous malformations may also occur in the area of the brain called the brainstem. Spinal cord and brainstem cavernous malformations can cause more severe symptoms when they hemorrhage. […] Seizures are one of the most common symptoms of cavernous malformation (cavernous angioma, cavernoma). Seizures fall into two general groups: focal seizures that are local to one area of the brain and generalized seizures that involve both sides of the brain. All cavernous malformation seizures begin as focal seizures but some progress to generalized seizures. Neurologists use anti-epilepsy medications to control seizures. However, neurosurgeons have had good results in eliminating seizures with brain surgery if they are able to pinpoint which cavernous malformation is causing the seizures. Surgery is most successful when it occurs within two years of a first seizure. Brainstem and spinal cavernous malformations do not cause seizures.

  https://www.alliancetocure.org/home/for-patients/newly-diagnosed/20-questions-answered-cavernous-malformation-angioma-cavernoma/

  We know people with cavernous malformation experience more frequent headaches than other people. A headache does not necessarily mean a new hemorrhage. For the most part, we can’t distinguish a cavernous malformation headache from any other kind of headache. A headache unlike one you have ever experienced or headaches, particularly on the same side or general location as your lesion, may be related to your lesion. A headache may be related to your cavernous malformation if it is unlike one you have ever experienced or if it is in the general location of your lesion. […] The symptoms of a cavernous malformation hemorrhage depend on its location and size. Cavernous malformations can cause attention, memory, social skills, mood, and learning problems, particularly if the lesions are in the frontal, parietal, or temporal lobes, or in the cerebellum, even without obvious bleeding. This is particularly true for individuals with many lesions throughout the brain.

  Cavernous malformations are clusters of abnormal, tiny blood vessels and larger, stretched-out, thin-walled blood vessels filled with blood and located in the brain. […] A person with a cavernous malformation may experience no symptoms. When symptoms occur, they often are related to the location of the malformation and the strength of the malformation walls. […] 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. […] Surgery should be considered for seizure control if: 1.) Seizures cannot be controlled through medication; 2.) The cavernous malformation is in a low risk, easily accessible area of the brain; and 3.) It has been determined that the lesion is causing the seizures.

  Cavernous malformations in many parts of the brain and spinal cord can cause weakness or numbness in the arms or legs. In some areas, such as the thalamus, they can also cause pain. A cavernous malformation in the brainstem can cause coordination problems called ataxia or can cause facial paralysis, usually on one side. […] Cavernous malformations can cause vision problems. There are two kinds of vision problems: those caused by lesions in the occipital lobe of the brain, which affect how visual information is processed, and those caused by lesions in the brainstem, which affect how the eyes work. […] A cavernous malformation can cause hearing problems, including loss of hearing and tinnitus, dizziness, or nausea, particularly if it is located in or near the cerebellum. […] A cavernous malformation hemorrhage in the brain can cause fatigue. Individuals may complain of fatigue for months to years after a major hemorrhage or brain surgery. […] Spinal cord cavernous malformations can cause numbness, weakness, paralysis, tingling, burning, or itching. The location and extent of the symptom depend on the level of the spine affected. Spinal cord lesions can also cause difficulty with bladder and bowel control.

[…] Problems can occur if the cavernoma bleeds or presses on certain areas of the brain. […] In most cases, bleeding is small usually around half a teaspoonful of blood and may not cause other symptoms. […] But severe haemorrhages can be life threatening and may lead to long-lasting problems. […] Any symptoms you have may come and go as the cavernoma bleeds and then reabsorbs blood. […] It’s important to closely monitor your symptoms, as any new symptoms might be a sign of a haemorrhage. […] The risk of having a haemorrhage varies from person to person, depending on whether you have experienced any bleeding before. […] If your cavernoma has bled previously, your risk of having another haemorrhage is somewhere between 4% and 25% each year.

  A cavernous malformation is a rare condition that can have a significant impact on your life. It is a cluster of abnormal, thin-walled blood vessels in the brain or spinal cord. This vascular disorder can cause neurological symptoms, but its exact cause is not entirely understood. However, it is believed to arise due to genetic mutations or sporadic development. In some cases, individuals with a family history of the condition may carry a mutated gene that can increase their likelihood of developing a cavernoma. Living with a cavernous malformation is challenging, both physically and emotionally, but it is possible to manage its symptoms and maintain a good quality of life with the right support and care. […] Physically, the symptoms of cavernous malformation vary depending on the location and size of the malformation. Some people may experience no symptoms at all, whereas others may experience headaches, seizures, weakness or numbness in the limbs, difficulty speaking or understanding language, or vision changes.

In these situations, cavernous malformation surgery can eliminate symptoms and restore normal functioning. […] During this time, activities like driving, lifting heavy objects or exercising strenuously will be restricted. You may want to enlist the help of a family member or friend for running errands and taking care of household tasks. […] Your doctors will schedule follow-ups to check the healing of your incision, watch for any emerging neurological or cognitive problems, such as weakness in limbs, or difficulties with speech, memory or coordination and will schedule periodic MRI or CT scans. Successful surgery for a cavernous malformation typically resolves the condition and its symptoms completely. […] Treating cavernous malformations depends on factors including your age, overall health, the size and location of the malformation and the nature of your symptoms.
