Core Tip
Core Tip: Alveolar echinococcosis is potentially fatal. In approximately 98% of cases, it manifests in the liver, similar to a primary malignant or metastatic tumour. The sonomorphological appearance of the disease is varied and easily confused with other differential diagnoses. Sonography is the most important tool in diagnostics, but how the known patterns change over time is unclear. The evidence that certain sonographic patterns in particular change over time shows a possible evolutionary approach to the disease and may, in the long term, make lifelong drug therapy unnecessary in non-operable patients when non-active stages can be clearly identified.
