FALLOPIAN TUBE ON ULTRASOUND 

Thanks

I am not sure of the significance but some literature suggest that it may be due to chronic inflammation. Thank you

Thanks so much. I also found some ways to observe tube in normal state, usually when it embraces the ipsilateral ovary.

Yes, especially peri-ovulatory with fluid around the ovary. Some sonologists are of the view that normal tubes can be seen with high frequency probes
