Introducing mirror syndrome - Otherwise known as Ballantyne syndrome or triple edema, mirror syndrome is a rare and extremely serious condition that affects pregnant women.

Very rare - First described by Scottish physician and obstetrician John William Ballantyne in 1892, there are fewer than 120 reported cases to date.

Overview -

Mirror syndrome happens when the fetus has an abnormal buildup of fluid and the mother has preeclampsia, a condition of high blood pressure.

Namesake -

This condition has come to be referred to as mirror syndrome, because it causes similar symptoms in mom and baby.

Early action -

While mirror syndrome can be very scary, it can be treatable. It is therefore important to recognize and communicate the symptoms.

Early action -

As with any pregnancy complication, early action is very important and can make all the difference when it comes to diagnosis and treatment.

Symptoms -

Mirror syndrome has several symptoms, some of which overlap with other conditions, such as preeclampsia. Professional examinations are therefore crucial.

In the mother - Symptoms of mirror syndrome in the mother can include significant and severe swelling, high blood pressure, and significant and excessive weight gain in a short period of time.

Protein in urine -

The condition may cause protein to build up in the mother’s urine. This can be easily diagnosed by a test at a clinic.

Hemodilution -

Sometimes mirror syndrome will also cause hemodilution, a condition where there is too much plasma in the blood and fewer red blood cells.

Hemodilution -

This can occur because of a fluid buildup in the body. And if it does occur, it will show up in a blood test.

Cause -

Because mirror syndrome is so rare, scientists are not sure of its exact cause. However, we do know it is often caused by something called fetal hydrops.

Fetal hydrops -

Fetal hydrops occurs when fluid leaves the bloodstream of the fetus and ends up in the tissues. There can be multiple causes.

Problem with fluid regulation -

Often, however, fetal hydrops develops from complications that compromise the natural ability of the fetus to regulate fluid.

Several causes -

Complications that can cause fetal hydrops include infection, genetic syndromes, heart problems, and metabolic disorders, among others.

Twin causes -

Sometimes, if a woman is pregnant with twins, twin-to-twin diffusion syndrome can cause fetal hydrops.

Diagnosis -

There is no specific test that can diagnose mirror syndrome. However, it can be diagnosed based on results from other tests.

Ultrasound -

The excess fluid in the lungs of the fetus, for example, is usually seen on an ultrasound.

Other tests -

Preeclampsia in the mother is generally diagnosed by her pregnancy care provider, based on blood pressure tests and/or the presence of protein in the urine.

Diagnosis -

These tests, along with self-reported symptoms and other observations made by the doctor, can inform a diagnosis of mirror syndrome.

Treatment - Because mirror syndrome is so rare, treatment depends on the specific situation. Often it is dictated by the underlying cause of the fetal hydrops.

Different options -

In deciding which treatment to use, doctors will also take the severity of the preeclampsia into account.

Different options -

If the underlying cause of the mirror syndrome is known, treating it can alleviate symptoms in both the fetus and the mother.

Delivery -

In other cases, particularly if the preeclampsia is serious, doctors may decide the baby needs to be delivered.

Mother's symptoms -

Once the baby has been delivered, the mother’s symptoms should clear up on their own in a matter of days.

Baby's symptoms -

The baby will usually spend some time in the newborn intensive care unit (NICU), while doctors determine the underlying cause of the hydrops and provide treatment.

When to seek medical attention -

If you or someone you know has symptoms of mirror syndrome or preeclampsia, it is very important to let a medical professional know.

© Shutterstock

When to seek medical attention -

Be sure to mention any symptoms, no matter how minor they may seem, to a doctor or other healthcare professional.

Speaking up -

While the symptoms may turn out to be nothing more than normal pregnancy pains, it is better to speak about it in case there is any cause for concern.

Speaking up -

Remember that while mirror syndrome can be very scary, it can be treatable. Early action is essential when it comes to diagnosing and treating this condition.
