Insights
Basilar impression, a treatable cause of childhood ataxia, involves bony abnormalities at the craniovertebral junction. Surgical intervention yielded positive outcomes for two pediatric patients presenting with ataxia and related neurological signs.
Area of Science:
- Neurology
- Pediatrics
- Orthopedic Surgery
Background:
- Ataxia is a frequent neurologic sign in children.
- Basilar impression, a bony abnormality of the craniovertebral junction, is an uncommon yet treatable cause of pediatric ataxia.
Observation:
- Two children presented with neck stiffness, ataxia, nystagmus, and corticospinal tract signs.
- Basilar impression was diagnosed via specific radiologic studies.
Findings:
- Surgical treatment was performed for both children.
- Both patients experienced favorable surgical outcomes.
Implications:
- Early recognition and surgical treatment of basilar impression can effectively manage pediatric ataxia.
- This highlights the importance of considering treatable structural causes for neurologic signs in children.
Abstract:
Ataxia is a common neurologic sign in childhood. Basilar impression due to bony abnormalities of the craniovertebral junction is an uncommon but readily treatable cause of ataxia in children. Two children who had neck stiffness, ataxia, nystagmus, and corticospinal tract signs are described. Basilar impression was recognized only after specific radiologic studies were performed. Both children were treated surgically with good results.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
