1

Hypertrophied column of Bertin

Unresorbed polar parenchyma of the kidney during embryological period
- pseudotumor

2

What does Hypertrophied column of Bertin contain?

Renal cortex

3

What is the renal cortex continuous with?

Adjacent renal cortex

4

Where is Hypertrophied column of Bertin located?

At the junction of upper and middle third

5

What does Hypertrophied column of Bertin demonstrate?

Renal pyramids and usually are < 3cm

6

What does a demonstration of arcuate arteries with colour doppler indicates?

An HCB, rather than a tumour

7

What can differentiate between a HCB and a tumou?r

CECT

8

CECT

Compound enhanced CT

9

Junctional Parenchymal (cortical) Defect

Normal variant located at the point of fusion of the embryological upper and lower poles

10

Where is Junctional Parenchymal (cortical) Defect commonly seen?

Right kidney

11

What does Junctional Parenchymal (cortical) Defect look like?

Triangular shape located at upper to mid kidney

12

What is Junctional Parenchymal (cortical) Defect also known as?

Interrenuncular junction

13

Is the exttrarenal pelvis a normal variant?

Yes

14

Extrarenal pelvis

Renal pelvis lies partly outside of the kidney

15

What can extrarenal pelvis be confused with?

Early obstruction

16

What are the 3 sets of kidneys in embryo?

1. Pronephros
2. Mesonephros
3. Metanephros

17

Where do the kidneys travel from?

The pelvis to the RUQ

18

How do the kidneys rotate as they travel?

Medially 90 degrees

19

When do the pronephroi develop?

Early in 4th week gestation

20

Pronephroi (2)

1. Rudimentary
2. Nonfunctioning

21

When do the mesonephroi develop?

Late in 4th week

22

What do the mesonephroi function as?

Interim kidneys

23

What do the metanephroi function as?

Permanent kidneys

24

What are the congenital anomalies that are related to growth? (3)

1. Hypoplasia
2. Fetal Lobulation
3. Compensatory Hypertrophy

25

Hypoplasia

Too few nephrons in a smaller than normal size kidney

26

What if hypoplasia is unilateral?

No symptoms

27

What if hypoplasia is bilateral

Renal insufficency

28

When is fetal lobulation present?

4-5 years of age

29

When does persistent lobulation occur?

If fetal lobulation doesnt get resolved

30

Fetal lobulation

Infolding of the cortex without loss of cortical parenchyma
