A sleep study can also help your healthcare provider decide if you need other treatment. Sleep apnea means that you stop and start breathing during sleep. You may need a sleep study if you have sleep apnea. You may need surgery, based on the MRI results or if symptoms get worse. It also looks at areas where the fluid is blocked. This test looks at the flow of spinal fluid. Your healthcare provider may suggest close monitoring of the defect with a special type of MRI called cine phase contrast. This is done to relieve pressure on the brain or restore the flow of spinal fluid. Your healthcare provider may prescribe medicines to reduce pain. This may include frequent physical exams and MRI tests. It will also depend on how severe the condition is.
Treatment will depend on your symptoms, age, and general health. These are experts in brain and spinal cord problems. You may be treated by a neurologist or neurosurgeon. How is a Chiari malformation type I treated? A CT scan is more detailed than a regular X-ray.
#CHIARI MALFORMATION TYPE 3 SERIES#
It uses large magnets and a computer to make detailed pictures of the inside of the body.ĬT scan.This test uses a series of X-rays and a computer to create detailed pictures of the inside of the body. MRI.This test is the one most often used to diagnose Chiari malformations. Your child may have 1 or more of these tests: Imaging tests are done to detect a Chiari malformation type I. If you have symptoms, your healthcare provider will ask about your health history and give you a physical exam. If you have no symptoms, the problem may be found when you have imaging tests for other reasons. How is a Chiari malformation type I diagnosed? Muscle weakness, lack of balance or abnormal reflexes Rapid, side-to-side eye movements (nystagmus) Other SymptomsĬhiari malformation symptoms can also include: A sleep study can confirm the presence of sleep apnea so a doctor can prescribe treatment. This is a serious sleep disorder characterized by brief interruptions in breathing during sleep. Sleep apnea is another problem that occurs in people with a Chiari malformation. The buildup of fluid causes the pressure inside of the head to increase and the child’s skull bones to expand to a larger-than-normal appearance. Type 2 Chiari malformations can also be associated with hydrocephalus, a condition in which there is an obstruction of the flow of cerebrospinal fluid that is found inside of the ventricles (fluid-filled areas) inside of the brain.
Toddlers, children and teens with undiagnosed type 1 Chiari malformations may develop headaches, which are typically located at the back of the head and neck, and are often made worse by exertion. In children younger than 16 whose spines are still growing, the presence of a syrinx can also be associated with the development of scoliosis, an abnormal, lateral (side-to-side) curvature of the spine. In these situations, an MRI scan may be needed for a definite diagnosis. Some children will show signs of a spine syrinx, but others will not. In some patients with a Chiari malformation, increasing pressure from a syrinx can affect neuromuscular function, causing limb weakness or difficulties with walking or breathing. As the cyst fills with cerebrospinal fluid, it expands, putting pressure on the spinal cord. This condition also known as syringomyelia. Signs and Symptoms of Chiari Malformations SyrinxĬhiari malformations are associated with the formation of a syrinx, a fluid-filled pocket, or cyst, in the spinal cord. This can happen because of an injury, contact with harmful substances, or an infection. It is caused by excess leaking of spinal fluid from the lower back (lumbar) or chest (thoracic) areas of the spine. Or it may be linked with genetic problems that run in families.Īn acquired Chiari malformation type I happens to a person after birth. It may be caused by contact with harmful substances during pregnancy. A problem during fetal growth may cause the defect. The exact cause of a congenital Chiari malformation type I is not known. What causes a Chiari malformation type I?
This is known as acquired or secondary Chiari malformation type I. In rare cases, this type may also develop later in life. But it is often not found until a person is a teen or young adult. It is also called primary Chiari malformation type I. In type I, the cerebellum bulges through the normal opening at the base of the skull. There are several types of Chiari malformations, but type I is the most common. In most cases, the problem is present at birth (congenital). This puts pressure on parts of the brain and spinal cord, and can cause mild to severe symptoms. A Chiari malformation is a problem in which a part of the brain (the cerebellum) at the back of the skull bulges through a normal opening in the skull where it joins the spinal canal.
