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 microcalcifications typical of the disease. This is also known as the bunch of grapes appearance.
The term may be used equally for the appearances on CT-IVP, especially when MIP images are employed to give coronal images similar to those from a traditional IVP.
