Area of Science:

Orthopedics
Radiology
Developmental Biology

Background:

Vertebral malformations encompass a spectrum of congenital anomalies affecting spinal development.
Segmentation and fusion anomalies are key categories of these developmental defects.

Observation:

A 42-year-old woman presented with an akinetic seizure and abnormal head posture.
Cervical spine imaging revealed an unusual vertebral anomaly.

Findings:

Computed tomography and polytomography demonstrated a unique block vertebral malformation.
The anomaly consisted of a butterfly vertebra superior to a pair of nonsegmented vertebrae.

Implications:

This case expands the known spectrum of vertebral fusion and segmentation anomalies.
Understanding such rare malformations is crucial for accurate diagnosis and management of spinal conditions.
