Ultrasound Diagnostics in Alveolar Echinococcosis: An Update.

BACKGROUND

Alveolar echinococcosis (AE) is a rare, potentially fatal zoonosis. In recent years, imaging diagnostics have become increasingly important compared to serologic diagnostics in AE. We will provide an overview of the importance of ultrasound diagnostics in AE in the detection of the disease and its significance in follow-up, as well as the typical sonographic presentation patterns and pitfalls.

SUMMARY

The use of the ultrasound classification developed by us and the use of contrast-enhanced ultrasound (CEUS) helps make the diagnosis faster and better. Without CEUS, the hemangioma-like pattern and the metastasis-like pattern in particular cannot be diagnosed with certainty. The limitations of ultrasound diagnostics on the patient side, in terms of examiner experience and equipment, remain.

KEY MESSAGES

Ultrasound is an important procedure in the detection and follow-up of AE. Contrast-enhanced sonography is indispensable. Fundamental limitations of ultrasound diagnostics such as examiner experience remain.
