Neurologist can help: The circle of willis, or willis polygon, is a ring of arteries (blood vessels carrying fresh oxygenated blood) that supply blood to the brain. Whether or not a malformation there causes problems depends on things such as where the abnormal artery is, is it too big or too small, is there still adequate blood flow through alternate arteries, etc... An angiogram can give a details of the arteries. ...Read more

When the embryo's forebrain does not divide to form bilateral cerebral hemispheres (the left and right halves of the brain), it causes defects in the development of the face and in brain structure and function.
In less severe cases, babies are born with normal or near-normal brain development and facial deformities that may affect the eyes, nose, and upper lip.The condition can be mild or severe. ...Read more
AVMs is general term: The word "arteriovascular" malformations could mean just arterial malformations or perhaps you are referring to arteriovenous malformations (avms) which occur arteries are connected directly to veins without any capillaries in between. The symptoms they cause (no symptoms, pain, bleeding, etc.) and how worrisome they are depends on their size and location. ...Read more

The tip or bottom of the cerebellum, the posterior brain controlling coordination, may extend be too low, and lie behind the spper spinal cord where it can get pinched.
Chiari is graded according to severity. Wickipedia has a good article on chiari malformation listing the grading. ...Read more
Can be symptomatic: Chiari malformation type i is neurological disorder where cerebellum (or more specifically the cerebellar tonsils), descends out of the skull into the spinal area, resulting in compression of parts of brain and spinal cord, and disrupts normal flow of cerebrospinal fluid.Type ii involves extension of both cerebellar and brain stem tissue into the foramen magnum. Associated with myelomeningocele. ...Read more
AVM: i think you must mean arteriovenous malformation. This represents a tangle of small arteries that become small veins. The significance is that they are prone to bleeding. They can be found in the brain, in the esophagus, the stomach, the liver, the small bowel, and the colon to name a few. ...Read more
Connection: This is a genetic abnormality that allows an artery to feed directly into a vein (instead of gradually perfusing tissue before being returned to the venous capillaries). This direct A-V communication creates what is called a shunt, and if large enough may cause volume overload on the heart, which may lead to hear chamber enlargement and even failure. At the site of the AVM, bleeding may result. ...Read more
Chiari malformation: A Chiari 1 malformation is an anatomical anomaly where a structure at the base of your brain called the cerebellar tonsils descend or herniated through the hole at the base of the skull called the foramen magnum ...Read more
Avm for short, a blood vessel abnormality in the brain:small capillaries fail to form in an are of the brain resulting in an abnormal tangle of vessels like a "can of worms"
about half of these go on to burst causing a stroke. Unfortunately that is the most common symptom. They may cause seizures, or headaches or changes in speech, vision or movement. My avm was of the acute bleed type. ...Read more
Not usually: Most lymphatic malformations are congenital, either lymphedema in legs or arms. Some lymphedema called lymphoma praecox does not become apparent until late first decade , second decade of life. Localized swellings, cystic hygromas, occur elsewhere in the body such as neck , abdomen. Acquired lymphedema in adults can occur related to radiation therapy for tumor or from breast surgery. ...Read more
Chiari malformation: A chiari 1 malformation can be totally benign and found on an mr for another reason or it can be symptomatic with headaches, dizziness, walking problems, swallowing issues among other findings.

Many people have a chiari malformation and no symptoms. Headaches can be associated with chiari malformations but headaches can arise from many other causes as well. ...Read more
It is: Chiari described different types of developmental defects of the cerebellum. Type 2 is associated with spina bifida, type 3 and type 4 are severe defects. You are probably talking about type 2 associated with spina bifida. It can cause breathing and swallowing problems. Treatment with surgery is controversial. ...Read more
Head/ Cervical MRI: Chiari malformation is best diagnosed with a head MRI without contrast to assess for the abnormal tonsil position and determine whether hydrocephalus, or water on the brain, is present also. A cervical MRI without contrast can assess for a problem called a syrinx, or a fluid cavity in the center of the spinal cord. A lumbar MRI without contrast can also exclude a tethered cord causing numb legs. ...Read more
