[Emergency indications for computed tomography of the skull in pediatrics]
Insights
Establishing clear indications for computed tomography (CT) scans in pediatric neurology is crucial. Emergency CT is vital for acute intracranial hypertension, hemorrhage, trauma, and unexplained coma in children.
Area of Science:
- Pediatric Neurology
- Neuroradiology
- Medical Imaging
Background:
- Careful establishment of computed tomography (CT) examination indications is essential.
- Emergency indications in pediatric neurology require specific definition.
- Acute intracranial hypertension is a principal emergency indication.
Purpose of the Study:
- To specify undisputed emergency indications for CT examinations in pediatric neurology.
- To describe the main radiological features associated with various etiologies of intracranial hypertension.
- To discuss the indications for CT and ultrasonography in neonates.
Main Methods:
- Review and specification of established emergency indications for CT in pediatric neurology.
- Description of radiological features for common causes of intracranial hypertension, including posterior fossa tumors and other space-occupying lesions.
- Discussion of CT and ultrasonography indications in neonates.
Main Results:
- Acute intracranial hypertension, with or without neurological signs or fever, is the primary emergency indication.
- Posterior fossa tumors are a major cause of intracranial hypertension, alongside other space-occupying lesions.
- Hemorrhage, trauma, and unexplained coma are other significant emergency indications for CT.
Conclusions:
- CT examinations in pediatric neurology should be guided by well-defined emergency indications.
- Understanding the radiological features of intracranial hypertension is key for diagnosis.
- CT and ultrasonography have distinct roles in neonatal neurological assessment.
Abstract:
Indications of CT examinations should be carefully established. Undisputed emergency indications in pediatric neurology are specified. Acute intracranial hypertension, whether isolated or associated with neurological signs or fever, is the principal emergency indication. Its main causes are posterior fossa tumors, but other space-occupying lesions may be found. The main radiological features in each etiology are described. Hemorrhage and trauma are the other essential emergency indications. Emergency CT examination can also be performed in unexplained coma. The indications of CT and ultrasonography in neonates are discussed.
