Bunch of grapes sign (bronchiectasis)

Last revised by Dr Mohamed Saber on 28 Nov 2021

The bunch of grapes sign, a.k.a. cluster of grapes sign, is a characteristic imaging finding on CT seen in bronchiectasis. Closely apposed dilated bronchi may look like multiple adjacent thin walled cysts which mimic the appearance of a bunch of grapes.
