What single feature would rule out a diagnosis of a complicated cyst?

• A. Solid intra cystic components
• B. Absence of any debris
• C. Thin walls
• D. Posterior acoustic shadowing

Answer: (A)

The main idea is that a cyst is defined by being fluid-filled and echo-free inside, with a smooth, thin wall and often posterior enhancement. A complicated cyst adds internal echoes due to debris or septations but stays primarily cystic. If you see a true solid component inside the cyst, that means there is solid tissue present within the lesion, which is not compatible with a cystic lesion. This finding shifts the lesion away from a cystic diagnosis toward a solid mass with cystic change, and it would prompt further evaluation rather than calling it a complicated cyst. In other words, a solid intracystic component would rule out classifying the lesion as a complicated cyst, because the presence of real solid tissue changes the category from cystic to a solid-dominant lesion.
