Bouquet of flowers appearance (medullary sponge kidney)
A bouquet of flowers appearance is a description given to the appearances of medullary sponge kidney on a traditional intravenous pyelogram (IVP) study. The ectatic distal collecting ducts contain the microcalcification typical of the disease. This is also known as a 'bunch of grapes' appearances.
The term may be used equally for the appearances on CT-IVP, especially when MIP images are reproduced to given static images similar to those from a traditional IVP.
