Vascular anomalies: what a radiologist needs to know.

Area of Science:

• Vascular anomalies
• Diagnostic imaging
• Paediatric radiology

Background:

• Haemangiomas and vascular malformations are typically diagnosed clinically.
• Accurate classification and understanding of clinical characteristics are vital for patient management.
• Atypical presentations and classification challenges necessitate advanced diagnostic tools.

Purpose of the Study:

• To discuss the role of imaging in classifying vascular anomalies.
• To highlight the utility of Doppler ultrasound and MRI in uncertain cases.
• To inform treatment choices and prognosis based on diagnostic findings.

Main Methods:

• Utilizing Doppler ultrasound for assessing superficial masses and haemodynamics.
• Employing MRI for evaluating lesion extent and anatomical relationships.
• Reviewing clinical criteria and diagnostic challenges in vascular anomalies.

Main Results:

• Doppler US effectively visualizes superficial masses and differentiates haemangiomas from malformations.
• MRI provides comprehensive evaluation of lesion extent and adjacent structures.
• Imaging aids in accurate diagnosis, guiding appropriate treatment and prognosis.

Conclusions:

• Radiologists play a key role in managing haemangiomas and vascular malformations.
• Intervention is critical for specific types of vascular malformations (VM, LM, AVM).
• Multidisciplinary team approach is essential for complex diagnostic and therapeutic management.
