Hydatid Cyst Imaging and Diagnosis

Well-circumscribed, hyperechogenic, and homogeneous mass with back wall attenuation as the tumour grows (correct)

Diffuse, hyperechogenic, and heterogeneous mass with central necrosis and strong back wall echoes

Irregular, hypoechoic, and heterogeneous mass with front wall attenuation as the tumour grows

Well-circumscribed, hypoechogenic, and homogeneous mass with front wall attenuation as the tumour grows

Hypoechoic irregular mass with posterior enhancement

Hypoechoic mass with well-defined margins and no internal echoes

Bright, echogenic convex line with acoustic shadowing (correct)

Diffuse hyperechoic mass with internal debris

Congenital cysts are hyperechoic and may contain debris, while alveolar echinococcosis presents as multiple bilateral cysts in the kidney

Congenital cysts are echo-free and without mural calcification, while alveolar echinococcosis may cause kidney enlargement (correct)

Congenital cysts are always enlarged and may show back wall attenuation, while alveolar echinococcosis presents as echo-free lesions

Congenital cysts appear as irregular masses with acoustic shadowing, while alveolar echinococcosis presents as a well-circumscribed, hyperechogenic mass
