An anomalous calyx in the mid-kidney: an anatomical variant.
Three cases in which there was an anomalous short calyx without a papilla in the mid kidney are described. This is believed to be a developmental abnormality which is associated with a pelvicalyceal pattern of two major calyces, and with renal "pseudotumour". It is important to recognize this calyceal appearance in order to distinguish it from calyceal disease.
