ABSTRACT

Diagnosis: Medullary Sponge Kidney

History: Hematuria

Findings: The collecting system and renal tubules appear normal. There are cylindrical collections of contrast in the renal papilla of the medulla of every calyx. This appearance is diagnostic of medullary sponge kidney.

Ddx: Renal papillary blush- this is caused by hyperconcentration of contrast material and is differentiated radiographically by the homogenous contrast enhancement of the renal papillary tips and absence of discrete collections of contrast and nephrocalcinosis. Papillary necrosis- the calyx is abnormal and there are pools of contrast in the medulla. Papillary necrosis may be seen on retrograde pyelography but MSK is not.

No MeSH data available.


Focal cylindrical collections of contrast are noted in each medullary region of both kidneys. The calyces appear normal and there is no nephrocalcinosis.
