Radiologic evaluation of pediatric hydrocephalus

Area of Science:

• Pediatric Radiology
• Neuroimaging
• Cerebrospinal Fluid Dynamics

Background:

• Pediatric hydrocephalus diagnosis and management present unique challenges.
• Conventional imaging (US, CT, MRI) shows ventricular enlargement but often lacks detailed obstructive information.

Purpose of the Study:

• To review the current role of radiology in evaluating pediatric hydrocephalus.
• To highlight the importance of advanced MRI sequences for diagnosis and treatment assessment.

Main Methods:

• Review of conventional imaging modalities: ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI).
• Focus on advanced MRI sequences: 3D CISS, cine PC, TSE, and GRE T2*.
• Evaluation of imaging's role in identifying cerebrospinal fluid (CSF) pathway obstructions.

Main Results:

• Ultrasound is useful for preterm infants with germinal matrix hemorrhages.
• CT demonstrates gross ventricular dilatation but requires further detail for obstruction assessment.
• MRI provides essential functional and anatomical information for hydrocephalus evaluation.

Conclusions:

• Advanced MRI sequences are vital for identifying obstructive pathology in the CSF pathway.
• Accurate neuroimaging is critical for patient selection in neuroendoscopic procedures.
• Standardized MRI protocols aid in assessing treatment efficacy for pediatric hydrocephalus.
