Marfan Syndrome in Children Explained by Dr. Sunil Gomber: A Clinical Case Every Pediatric Resident Should Know

Not every important diagnosis begins with dramatic symptoms.

Sometimes, a child walks into the OPD with common complaints like stomach pain or feeling weak. It seems like a routine case. But if you look closely, the body gives you clues that point towards something much bigger.

That’s exactly what happened in one of Dr. Sunil Gomber’s pediatric case discussions. What looked like an ordinary consultation slowly turned into a classic case of Marfan syndrome a condition every MD and DNB Pediatrics resident should know how to identify.

Let’s understand how the diagnosis unfolded.

It Started with a Simple Complaint

A 10-year-old girl came to the hospital with two complaints:

Pain in the abdomen for the past 2–3 months

Generalized weakness

Her vital signs were normal. Blood pressure and pulse were also within the expected range for her age. At first, there wasn’t anything that immediately suggested a serious illness.

But medicine isn’t only about listening to symptoms. It’s also about observing the patient carefully.

The Physical Examination Changed Everything

During the examination, a few things caught the doctor’s attention.

The child looked taller than expected for her age, and her fingers were unusually long and slender. When her height and arm span were measured, another important clue appeared.

Height: 153 cm

Arm span: 159.5 cm

Normally, a person’s arm span is almost equal to their height. In this child, the arm span was noticeably longer.

That small finding made the doctors think beyond routine causes of abdominal pain and weakness.

Another Clue Came from the Heart

During the cardiac examination, the doctor heard an ejection of systolic murmur.

Now the picture is becoming clearer.

The child had:

Long, slender fingers (arachnodactyly)

Arm span greater than height

A heart murmur

When these findings are seen together, Marfan syndrome becomes an important possibility.

This case reminds us why a careful clinical examination is still one of the most powerful tools in medicine.

Confirming the Diagnosis

To investigate further, the child underwent echocardiography.

The scan showed:

A bicuspid aortic valve

Aortic root dilatation

Mild aortic regurgitation

Since heart problems are commonly seen in Marfan syndrome, these findings supported the diagnosis.

The doctors also requested an eye examination.

Although the child did not have ectopia lentis (dislocation of the eye lens), she did have myopia, another feature that can be seen in Marfan syndrome.

What is Marfan Syndrome?

Marfan syndrome is an inherited connective tissue disorder caused by a mutation in the FBN1 gene.

Because connective tissue is present throughout the body, the condition can affect different organs, especially the:

Heart and blood vessels

Eyes

Bones and joints

Lungs

This is why children with Marfan syndrome may not come with just one symptom. Instead, they often have signs involving multiple body systems.

The Biggest Lesson from This Case

The most valuable takeaway isn’t just learning about Marfan syndrome.

It’s learning how experienced clinicians think.

A child came in with abdominal pain and weakness. But instead of stopping there, the doctor noticed the child’s body proportions, listened carefully to the heart, connected the findings, and reached the correct diagnosis.

That’s the kind of clinical thinking every pediatric resident should develop.

In the next part, we’ll simplify the Revised Ghent Criteria, understand the thumb sign and wrist sign, discuss treatment, complications, and learn the exam points that every MD/DNB Pediatrics resident should remember.

Learn Clinical Pediatrics the Way It Is Practiced

Reading textbooks is important, but seeing how experienced pediatricians approach real cases helps you develop clinical reasoning much faster.

Conceptual Pediatrics is designed with that goal in mind. Through case-based discussions, practical explanations, and exam-focused teaching by experienced faculty, it helps MD and DNB residents strengthen both their clinical approach and their preparation for university exams, ward rounds, and entrance examinations.

Whether you’re preparing for your residency, postgraduate exams, or simply want to become more confident in managing pediatric cases, Conceptual Pediatrics makes learning practical, structured, and easy to understand.
