Imaging approach to pediatric calvarial bulges.

Area of Science:

• Pediatric Radiology
• Neuroradiology
• Medical Imaging

Background:

• Palpable calvarial lesions in children present with non-specific clinical features, necessitating comprehensive evaluation.
• The differential diagnosis for pediatric calvarial bulges spans benign to aggressive pathologies, requiring careful characterization.
• While some lesions require tissue sampling, many can be diagnosed through characteristic imaging appearances.

Purpose of the Study:

• To review and illustrate the imaging findings of common and clinically significant focal pediatric calvarial bulges.
• To assist radiologists in narrowing the differential diagnosis for these lesions.
• To guide appropriate referral pathways based on imaging characteristics.

Main Methods:

• This is a review article, synthesizing information from existing literature.
• Focuses on illustrating imaging findings of pediatric calvarial lesions.
• Categorizes lesions into birth-related, congenital abnormalities, modeling disturbances, normal variants, and neoplastic lesions with mimics.

Main Results:

• The review provides a visual and descriptive guide to the imaging appearance of various pediatric calvarial bulges.
• It highlights key imaging features that differentiate benign from malignant or aggressive conditions.
• Emphasis is placed on lesions identifiable through imaging, potentially avoiding invasive procedures.

Conclusions:

• An informed, multi-modality imaging approach is crucial for characterizing pediatric calvarial lesions.
• Radiologists can effectively narrow differential diagnoses by recognizing typical imaging patterns.
• This review serves as a resource to improve diagnostic accuracy and guide patient management.
