Correct Answer » D Explanation

Ans:D. Renal System.

The facies shown in photograph above represents Potter facies.

Potter sequence

It is a constellation of findings demonstrated postnatally as a consequence of severe, prolonged oligohydramnios in utero.
It consists of :

• pulmonary hypoplasia: often severe and incompatible with life
• growth restriction (IUGR)
• abnormal facies (Potter facies)

1. low set ears
2. prominent infraorbital folds
3. flattened nose
4. wrinkled skin
5. micrognathia
6. widely seperated eyes with epicanthic folds

• limb abnormalities: including club feet and contractures

Pathology

Although originally associated with renal causes of olighydramnios, the Potter sequence may be seen with severe oligohydramnios of essentially any cause.

Common aetiologies include:

• fetal renal insufficiency

• bilateral renal agenesis: traditionally known as the classic Potter syndrome

• autosomal recessive polycystic kidney disease

• posterior urethral valves, and other causes of antenatal renal tract obstruction

• premature rupture of membranes (PROM)

• twin-twin transfusion
