Why are these illustrations important?

Myelomeningocele is a severe form of spina bifida in which the spinal cord and surrounding membranes protrude through an opening in the spine. It is an important associated condition, especially in Chiari Type 2.

CBC also created an axial comparison of a normal spinal cord and a spinal cord with a syrinx to help show how a syrinx changes the structure of the cord. Together, these illustrations help make related and often complex spinal anatomy easier to understand.

For Chiari Awareness Month, CBC is sharing resources created for the entire Chiari community to help make complex anatomy and medical topics easier to understand. CBC is also committed to periodically reviewing and updating these illustrations as new research, information, and areas of medical consensus emerge.

💜 Meet Mike, Crazy By Chiari’s Development & Program Coordinator.

For Chiari Awareness Month, we’re honoring members of the CBC team whose connection to Chiari is personal.

Mike’s story began years before he knew what Chiari was.

At just 13 years old, while playing baseball, he discovered that tightening his baseball cap as much as possible seemed to ease his headaches. At the time, those headaches were dismissed as adolescent migraines that were expected to fade with age.

They didn’t.

Instead, the headaches followed Mike into adulthood and eventually became severe enough to dramatically affect his life. Before decompression surgery, he was also diagnosed with two transient ischemic attacks.

During one especially frightening episode, the people around him feared he might not survive. When the possibility of calling a priest for Last Rites was raised, Mike’s response was simple:

“I’m not dead yet.”

In January 2013, Mike underwent Chiari decompression surgery.

More than a decade later, he has never required a revision, and the devastating headaches that once controlled so much of his life have not returned.

But his story also reflects something important about Chiari: improvement does not always mean every symptom disappears.

Mike still experiences lasting effects, including ongoing pressure sensations in his head, despite no longer having the severe headache pain he once knew.

His journey from unexplained childhood symptoms, to diagnosis, to surgery, and now life more than a decade after decompression gives him a perspective that cannot be learned from a textbook.

At CBC, Mike brings that lived experience into his work helping develop programs and strengthen the organization for the people we serve.

We are proud to have him on our team.

Why is the Chiari Type 4 illustration important?

Chiari Type 4 is an extremely rare and severe condition characterized by hypoplasia or aplasia of the cerebellum, meaning the cerebellum is underdeveloped or portions may be absent.

Unlike other Chiari types, the cerebellum may remain in its normal position and the foramen magnum is typically normal. This illustration helps show why Type 4 is anatomically very different from the other Chiari classifications.

Why is the Chiari Type 3 illustration important?

Chiari Type 3 is a rare and severe form of Chiari malformation in which cerebellar and brainstem tissue herniate through an opening at the back of the skull, often into an encephalocele at the foramen magnum.

Because Chiari Type 3 can involve major brain and spinal abnormalities including encephalocele, hydrocephalus, syringomyelia, and other neurological complications**—this illustration helps show the complexity and seriousness of the condition.

Why is the Chiari Type 2 illustration important?

Chiari Type 2 is defined by herniation involving the cerebellar vermis, brainstem, and fourth ventricle. It is a more complex form of Chiari and is almost always associated with additional brain and spinal abnormalities.

Because Chiari Type 2 is commonly linked with **myelomeningocele, hydrocephalus, syringomyelia, and tethered cord**, this illustration helps show the broader anatomical changes that can be involved.

💜 Meet Karrin, Crazy By Chiari’s Community Resource Coordinator.

For Chiari Awareness Month, we’re honoring members of the CBC team whose connection to Chiari is personal.

Karrin’s journey began in 2016, only months after starting a master’s program in Computer Science.

Her initial imaging showed cerebellar tonsillar ectopia, with her herniation falling just below the commonly used measurement for a Chiari I diagnosis. But Karrin wasn’t comfortable allowing a single measurement to be the end of the conversation.

She kept asking questions.

After advocating for an upright MRI, imaging showed an additional 2–3 mm of herniation while upright. That persistence eventually led her to Chiari specialists at the Colorado Chiari Institute, and in 2021, she underwent decompression surgery.

But Karrin didn’t stop searching for information once she found her own answers.

Over time, the collection of Chiari resources she had gathered for herself grew into GiveMyBrain.Space a centralized resource hub designed to make the enormous and often scattered world of Chiari information easier for others to navigate.

What began as bookmarks became something she describes beautifully as “a fellow traveler’s map.”

That same instinct to research deeply, organize what she finds, and make complicated information easier for someone else to access is exactly what Karrin brings to CBC.

Professionally, she has 8 years of experience in QA Engineering and now works as a Technical Compliance QA Manager, bringing a methodical and detail-focused approach to everything she does.

As our Community Resource Coordinator, Karrin helps us find, organize, and connect people with resources so they don’t have to navigate the Chiari world search by search.

We are proud to have her on our team.

Why is the Chiari Type 1.5 illustration important?

Chiari Type 1.5 shares features of both Chiari Type 1 and Type 2. In addition to low-lying cerebellar tonsils, there is downward displacement of the brainstem, including a lower position of the obex (the anatomical landmark at the lower end of the fourth ventricle.)

Unlike Chiari Type 2, Type 1.5 is not associated with a neural tube defect. This illustration helps show the anatomical differences that distinguish Type 1.5 from other forms of Chiari.

Why is the Chiari Type 1 illustration important?

Chiari Type 1 is the most common form of Chiari malformation and occurs when the cerebellar tonsils extend into the foramen magnum, the opening between the skull and spinal canal.

Because Chiari Type 1 can appear both with and without syringomyelia, CBC created illustrations showing both presentations to help make these anatomical differences easier to understand.

For Chiari Awareness Month, CBC is sharing resources created for the entire Chiari community to help make complex anatomy and medical topics easier to understand. CBC is also committed to periodically reviewing and updating these illustrations as new research, information, and areas of medical consensus emerge.

Crazy by Chiari has officially launched a **$3,500 GoFundMe** to help support our advocacy, educational outreach, resources, and upcoming presence at the Congress of Neurological Surgeons Annual Meeting.

CBC was built on one core belief: patients and neurosurgeons both deserve to be heard.

We advocate for both sides because both sides matter and every donation, no matter the size, helps us continue building that bridge.

If you can donate or even just share, it means more than you know. 💚

When millimeters matter, communication matters more.

Why is the Chiari Type 0.5 illustration important?

Chiari Type 0.5 is a newer classification that may not fit the traditional idea of Chiari based only on how far the cerebellar tonsils descend.

Instead, the focus is on ventrolateral tonsillar wrapping, crowding at the foramen magnum, and compression of the caudal medulla (lower brainstem). This makes it important to look at the overall spatial relationships and tissue compression at the craniocervical junction, not just millimeter measurements.
