Insights

Occult craniocervical junction injuries in children are often missed by CT scans but detected by MRI. Younger children and those in motor vehicle accidents are at higher risk.

Area of Science:

  • Pediatric Radiology
  • Trauma Imaging
  • Neurosurgery

Background:

  • Craniocervical junction injuries pose diagnostic challenges in pediatric patients.
  • Standard imaging like CT may not detect subtle or occult injuries.

Purpose of the Study:

  • To review the incidence of occult craniocervical junction injuries in children.
  • To identify risk factors and associated injuries in pediatric craniocervical trauma.

Main Methods:

  • Retrospective review of patients under 18 with negative CT and subsequent MRI of the craniocervical junction (July 2003 - June 2008).
  • Data collected included age, gender, injury mechanism, and associated injuries below C2.
  • Analysis of MRI findings to determine significant craniocervical junction injuries.

Main Results:

  • 30 of 45 patients with negative CT had positive MRI findings.
  • 17 of these 30 patients had significant craniocervical junction injuries.
  • Significant injuries were more common in children under 8 (11/17) and those involved in motor vehicle accidents (13/17).
  • Lower cervical spine injuries (below C2) were associated with craniocervical injury in 6 of 12 patients.

Conclusions:

  • Pediatric craniocervical injuries are frequently occult on CT but visible on MRI.
  • Younger children, motor vehicle accidents, and lower cervical spine injuries are associated with higher risk.
  • MRI is crucial for diagnosing subtle craniocervical junction injuries in children.

Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
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...

Cranial Bones: Superior and Posterior View

The superior view of the cranium shows the frontal and paired parietal bones.
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 and Spinal Meninges01:19

Cranial and Spinal Meninges

The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
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...
Increased Intracranial Pressure ll: Pathophysiology01:29

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
