Which feature is commonly associated with macrocystic cystadenoma?

• A. Multiloculated
• B. Uniloculated
• C. Calcified wall only
• D. Diffuse homogeneous echotexture

Answer: (A)

Macrocystic cystadenoma is best described by its multiloculated cystic nature. The term macrocystic implies several large cystic spaces within the mass, so on ultrasound you see multiple compartments separated by thick septa rather than a single chamber. This multiloculated appearance differentiates it from a uniloculated lesion (which suggests a simple or serous cystadenoma), from a wall that is calcified (seen with other tumor types or degenerative changes), or from a diffusely homogeneous echotexture (typical of a simple cyst or solid mass without multiple locules).
