Summary
Pierre-Robin syndrome (PRS) can be associated with Chiari malformation type I. Surgical decompression relieved cerebellar tonsil herniation in a 15-year-old patient with PRS.
Area of Science:
- Neurology
- Pediatrics
- Genetics
Background:
- Pierre-Robin syndrome (PRS) is a rare congenital condition characterized by severe micrognathia and cleft palate.
- Craniovertebral anomalies can occur in PRS, potentially leading to neurological complications.
Observation:
- A 15-year-old male with PRS presented with occipital headache and gait disturbance.
- Radiological evaluation revealed severe cerebellar tonsil herniation and craniovertebral osseous anomalies.
Findings:
- The patient underwent foramen magnum decompression (FMD) with duroplasty.
- Postoperative MRI confirmed successful decompression of the cerebellar tonsils.
Implications:
- This case highlights a potential association between PRS and Chiari malformation type I.
- Understanding the embryological link may elucidate the pathophysiology of Chiari I malformation in PRS patients.
- This is the first reported case of PRS associated with Chiari malformation type I, expanding the spectrum of PRS-related complications.
