Hepatic hydatid cyst disease in low- and middle-income countries: Spectrum of imaging findings and complications

Figure 2 Cystic echinococcosis 1 hydatid cyst. A and B: Ultrasound and images showing a lobulated cystic lesion in the right lobe of the liver with a well-defined wall (arrow in A) and an echogenic nodule at its base (arrow in B), most likely corresponding to cystic echinococcosis 1 with hydatid sand; C: Axial computed tomography image depicts a non-specific low-attenuation cyst (arrow) with subtle pseudo-enhancement, highlighting the superior sensitivity of ultrasound for characterization of early-stage disease.
