How to Pronounce Chiari Malformation

Say it like this: kee-AR-ee mal-for-MAY-shun. The first part rhymes with "key," the second part sounds like "ARE," and you say the last part like "mal" (rhymes with "pal") plus "for" plus "MAY" plus "shun."

The stress falls on the second syllable of each word: kee-AR-ee (AR gets the stress) and mal-for-MAY-shun (MAY gets the stress). A common mistake is stressing the first syllable of "Chiari," but it's actually "AR" that should sound louder.

Break it into five syllables: chi-ar-i mal-for-ma-tion. When you say it naturally at normal speed, it flows together, but these are the separate sound pieces.

"Malformation" comes from two parts: "mal" means bad or wrong, and "formation" means the way something is shaped or formed. So a malformation is something that formed in an abnormal or unusual way.

Chiari is named after Hans Chiari, an Austrian doctor who first described this condition in detail in the 1890s. Medical conditions are often named after the doctors who first identified or carefully studied them.

Yes, doctors often call it "CM" or simply "Chiari" for short. You say "CM" by saying each letter separately: C-M.

In plain English, a Chiari malformation is a structural condition where part of the brain is shaped differently than usual. The term describes the unusual structure itself, not what causes it or how to treat it.

Other words use "malformation" the same way: "cardiac malformation" (heart shaped wrong), "facial malformation" (face shaped wrong), and "limb malformation" (arm or leg shaped wrong). They all describe body parts that formed in an unusual way.
