Imaging Spectrum of Calvarial Abnormalities.

Area of Science:

• Radiology
• Pathology
• Skull Anatomy

Background:

• Calvarial abnormalities are often found incidentally on imaging.
• Symptoms are less common but can occur.
• Imaging features are key to diagnosis.

Purpose of the Study:

• To review the imaging spectrum of calvarial abnormalities.
• To correlate imaging findings with clinical information for diagnosis.
• To provide a comprehensive overview for radiologists.

Main Methods:

• Narrative review of existing literature and imaging studies.
• Analysis of imaging features associated with various calvarial conditions.
• Categorization of abnormalities based on etiology and imaging patterns.

Main Results:

• Calvarial abnormalities present with diverse imaging findings, including focal bone loss, lytic, sclerotic, or mixed lesions.
• Causes range from trauma, surgery, infection, and inflammation to idiopathic disorders, congenital lesions, tumors, and metabolic diseases.
• Imaging features like extent, multiplicity, and specific characteristics help narrow differential diagnoses.

Conclusions:

• Imaging plays a crucial role in evaluating calvarial abnormalities.
• Integrating imaging findings with clinical data is essential for accurate diagnosis.
• This review provides a framework for understanding the imaging spectrum of skull lesions.
