38 year Old female with Complete Duplication of the right kidney and upper pole moiety showing atrophy and partial duplication of the left kidney
CT of the kidneys in the coronal plane in the nephrographic phase 70 seconds after injection in a 38year old female shows a duplicated right collecting system with atrophy of the upper pole moiety (yellow arrowhead lower image). The right kidney shows a prominent column of Bertin (maroon arrowhead lower image)

CT of the kidneys in the axial plane in the nephrographic phase 70 seconds after injection in a 38year old female shows a duplex right collecting system with atrophy of the upper pole moiety (yellow arrowhead lower image). The right kidney shows a prominent column of Bertin (maroon arrowhead lower image)

CT of the kidneys in the coronal plane in the excretory phase 10 minutes after injection in a 38year old female shows a collecting systems of the upper pole components of the duplex systems filled with contrast (yellow arrowheads b for the right side and c for the left) The column of Bertin on the left (c maroon arrowhead) separates the upper and lower moieties of the partial duplication on the left .

CT of the kidneys in the axial plane in the excretory phase 10 minutes after injection in a 38year old female shows a hydronephrotic collecting systems of the upper pole components of the duplex systems filled with contrast (yellow arrowheads b) and evidence of post obstructive atrophy. The left extrarenal collecting system is of normal caliber as a common ureter (c yellow arrowhead) The column of Bertin on the left is noted (c maroon arrowhead

CT of the kidneys in the coronal plane in the excretory phase 10 minutes after injection in a 38year old female shows mild hydroureter of the upper pole moiety (medial ureter) and normal caliber ureter of the right lower moiety (latera ureter)

MRI Pre Contrast
Pre contrast T1 weighted MRI through the kidneys show the atrophied right upper pole moiety in a 38year old female

Cortical Phase at 20 Seconds after Contrast
20 seconds following contrast, the T1 weighted MRI through the kidneys show the atrophy of the right upper pole moiety with irregular thinning of the right renal cortex

Corticomedullary Phase at 70 Seconds
70 seconds following contrast, the T1 weighted MRI through the kidneys show the atrophy of the right upper pole moiety with indication of perfusion of the atrophied corticomedullary parenchyma. The right lateral edge of the atrophied kidney does partial volume with the normal lower pole parenchyma, and therefore the medial parenchyma reflects the true parenchyma of the upper pole moiety. Note also the column of Bertin of the left kidney

Nephrographic and Excretory Phase at 3 minutes after Contrast –
3 minutes following contrast, the T1 weighted MRI through the kidneys show atrophy of the right upper pole moiety with indication of progressive perfusion of the atrophied parenchyma. The right lateral edge of the atrophied kidney does partial volume with the normal lower pole parenchyma, and therefore the medial parenchyma reflects the true parenchyma of the upper pole moiety. Contrast is now also seen in the collecting system of the right kidney. A column of Bertin is noted in the left kidney

The dilated intrarenal collecting system of the upper pole moiety is seen with associated pressure atrophy. A column of Bertin is noted extending toward the hilum of the left kidney
