Comments and illustrations of the WFUMB CEUS liver guidelines: Rare vascular pathology, part II

Area of Science:

• Vascular Diseases
• Medical Imaging
• Hepatology

Background:

• Acute hepatic vascular diseases, including pseudoaneurysm, infarction, and pylephlebitis, are critical and potentially fatal conditions.
• Early recognition and accurate diagnosis are essential for effective management.

Purpose of the Study:

• To describe the ultrasonographic appearance of hepatic pseudoaneurysm, hepatic infarction, and pylephlebitis.
• To highlight Zahn's pseudo infarction as a differential diagnosis for hepatic infarction.
• To improve awareness and diagnostic accuracy of these rare hepatic vascular conditions.

Main Methods:

• B-mode ultrasonography
• Duplex ultrasonography
• Contrast-enhanced ultrasonography

Main Results:

• Detailed descriptions of the ultrasonographic findings for hepatic pseudoaneurysm, infarction, and pylephlebitis.
• Identification of Zahn's pseudo infarction as a key differential diagnosis.
• Emphasis on the role of advanced ultrasound techniques in visualizing these pathologies.

Conclusions:

• Ultrasonography is crucial for diagnosing acute hepatic vascular diseases.
• Awareness of rare findings and differential diagnoses like Zahn's pseudo infarction improves patient outcomes.
• Correct interpretation of ultrasound images facilitates timely diagnostic and therapeutic interventions.
