Modality:

IVU.

Description:

A small area of pooling of contrast noted adjacent to upper pole calyceal system. Normal appearing pelvicalyceal system.

Diagnosis:

Calyceal diverticulum.

Key Points:

The term calyceal diverticulum or pyelocalyceal diverticulum refers to a urine-containing cystic cavity within the renal parenchyma. Calyceal diverticula containing calculi remain an uncommon urological condition, although when present are frequently symptomatic.

It is important for both the uroradiologist as well as the general radiologist to be familiar with their appearances, thus avoiding diagnostic uncertainty and unnecessary investigation for suspected complex renal cysts. A combination of imaging modalities might be necessary to reach a definitive diagnosis in difficult cases.
