Craniosynostosis in the presence of a sinus pericranii: case report
1Department of Neurosurgery, Juntendo University School of Medicine, Tokyo, Japan.
Insights
A rare case of craniosynostosis in an infant showed elevated intracranial pressure but also a surprisingly high pressure-volume index, suggesting unique pressure-buffering capacity. This finding offers new insights into managing such complex pediatric neurological conditions.
Area of Science:
- Pediatric Neurology
- Neurosurgery
- Craniofacial Anomalies
Background:
- Craniosynostosis, the premature fusion of skull sutures, can lead to increased intracranial pressure.
- Venous sinus stenosis and sinus pericranii are rare associated conditions that can complicate management.
- Understanding intracranial pressure dynamics is crucial for effective treatment.
Observation:
- A 16-month-old girl presented with craniosynostosis, venous sinus stenosis, and sinus pericranii.
- Intracranial pressure monitoring revealed elevated cerebrospinal fluid outflow resistance and intracranial hypertension.
- Remarkably, the pressure-volume index, a measure of pressure-buffering capacity, was significantly elevated despite the hypertension.
Findings:
- This case presents a unique combination of craniosynostosis with venous anomalies and paradoxical pressure-volume index elevation.
- The elevated pressure-volume index suggests an unusual compensatory mechanism for intracranial hypertension in this specific condition.
- This represents a novel case not previously reported in medical literature.
Implications:
- The findings challenge current understanding of intracranial pressure regulation in complex pediatric craniofacial anomalies.
- Further research into the mechanisms of pressure-volume index elevation in such cases is warranted.
- This case may inform novel management strategies for infants with craniosynostosis and associated venous abnormalities.
Abstract:
The case of a 16-month-old baby girl with craniosynostosis associated with venous sinus stenosis and sinus pericranii is reported. Monitoring of intracranial pressure indicated increased cerebrospinal fluid outflow resistance in addition to increased intracranial pressure. Despite intracranial hypertension, however, the pressure-buffering capacity, expressed as pressure-volume index, was remarkably elevated. A similar case has not been reported in the literature. The mechanism of pressure-volume index elevation and the management of this anomaly are discussed.

Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
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,...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
