Waist sign hydrosalpinx

Last revised by Frank Gaillard on 21 Aug 2020

The waist sign arises from the folding of a distended tube upon itself producing indentations on diametrically opposite sides. The waist sign is specific for hydrosalpinx and virtually pathognomonic when seen in association with a tubular-shaped cystic mass.
