A 43-year-old female patient presented with abdominal pain and malaise. (a) Abdominal ultrasound examination reveals a hyperechoic, heterogeneous solid mass lesion that fills part of the right lobe and the entirety of the left lobe of the liver. Its borders can be clearly discerned from the adjacent normal hepatic parenchyma (arrowheads). The necrotic cavity in the central zone of the lesion appears as a hypoechoic area with irregular contours (asterisk). (b) Calcifications around the central necrotic zone can be discerned as hyperechogenic foci (arrowheads). (c) An axial contrast-enhanced CT image demonstrates the hypovascular solid mass lesion more clearly. The necrotic cavity in the left lobe (asterisk) and the tiny calcifications around it are visible. Additionally, note that the lesion causes a retraction in hepatic contours. (d) A coronal T2W MRI image shows a heterogeneous mass lesion that is mildly hypointense relative to liver parenchyma. While the necrotic cavity in the center of the lesion appears of high signal intensity, the calcifications are not easily discernible.
