Chiari zero malformation with syringobulbia

Area of Science:

• Neurology
• Neurosurgery
• Medical Genetics

Background:

• Chiari zero malformation is a rare subtype of Chiari malformations.
• It is characterized by symptoms similar to Chiari malformations but without cerebellar herniation.
• Syringomyelia and, rarely, syringobulbia can be associated findings.

Observation:

• A case report of a 39-year-old patient diagnosed with Chiari zero malformation.
• The patient presented with symptoms indicative of Chiari malformation.
• No cerebellar tonsillar ectopia or herniation was observed on imaging.

Findings:

• The patient was diagnosed with Chiari zero malformation.
• The condition was associated with both syringomyelia and syringobulbia.
• This presentation underscores the complex and varied neurological manifestations of Chiari zero.

Implications:

• This case expands the understanding of Chiari zero malformation's clinical spectrum.
• It emphasizes the importance of considering syringomyelia and syringobulbia in the differential diagnosis.
• Further research is needed to elucidate the pathogenesis and optimal management of Chiari zero.
