Spectrum of Imaging Manifestations of Vascular Malformations and Tumors Beyond Childhood: What General Radiologists...

Area of Science:

• Radiology
• Vascular Imaging
• Pathology

Background:

• Vascular anomalies present diverse clinical and imaging features.
• Accurate diagnosis is crucial for appropriate management.
• Existing classifications guide the understanding of these conditions.

Purpose of the Study:

• To review diagnostic imaging findings of non-central nervous system vascular anomalies in adults.
• To provide a framework for understanding vascular malformations and tumors.
• To highlight common and important rare entities for radiologists.

Main Methods:

• Literature review based on the International Society for the Study of Vascular Anomalies classification.
• Focus on imaging findings (e.g., MRI, CT, ultrasound).
• Inclusion of entities encountered beyond childhood.

Main Results:

• Detailed imaging characteristics of various vascular malformations (e.g., venous, lymphatic, arteriovenous).
• Imaging features differentiating vascular tumors (e.g., hemangiomas, hemangioendotheliomas).
• Emphasis on distinguishing features for common and rare vascular anomalies.

Conclusions:

• A systematic approach using established classification aids in diagnosing adult vascular anomalies.
• Familiarity with imaging findings is essential for radiologists.
• This review serves as a practical guide for the interpretation of vascular lesions.
