Suspected abscess in the liver:


Liver abscess (2D and CEUS). 2D Examination reveals the fluid nature of the mass and imprecise delineation. CEUS examination shows congestion in the surrounding liver parenchyma and excludes a vascular tumor.

Liver abscess have heteromorphic ultrasound appearance, the most typical being that of a mass with irregular shapes, fringed, with fluid or semifluid content, with or without air inside.[1] Doppler examination shows the lack of vessels within the lesion. CEUS exploration shows hyperenhancement during arterial phase close to the lesion, this being suggestive of a liver parenchymal hyperemia. During venous and sinusoidal phase the pattern is hypoechoic, and the central fluid is contrast enhanced. CEUS examination is useful because it confirms the clinical suspicion of abscess. In addition, it allows for an accurate measurement of the collection size and an indication regarding its topography inside the liver (lobe, segment).[1]
