sunshine9402,
It only means, there is a cyst.
what is Avascular Anechoic Tubular convoluted cystic structure
Welcome to the community. The "avascular anechoic" would make me think it is a fluid-filled functional cyst that is a normal part of the menstrual cycle. However, sometimes functional cysts can hang around longer than normal and get larger but most do resolve on their own in 2 to 3 cycles. I don't know if "tubular" refers to the shape or that it is in the Fallopian tube. Please get clarification from your doctor. Let us know what you find out.
