DX: Beckwith-Wiedemann Syndrome

Patient had soft tissue swelling asymmetry only right arm and leg. There was no evidence of fracture or bone anomaly. On x-ray we can show enlargement of the liver because lower border is inferiorly located. Ultrasound measurements (not shown) of liver and right kidney were above normal. Spleen and left kidney were normal in size.

Here are the X-ray images:

One thing I failed to mention is that patient had recurrent episodes of hypoglycemia. This lab test finding coupled with x-ray findings of hemihypertrophy are almost conslusive of Beckwith-Wiedemann Syndrome.

The most important recommendation you can give as a Radiologist is that this baby will need anual screening during his entire lifetime because it's one of the Cancer Predisposition Syndromes in children.

Beckwith–Wiedemann syndrome BWS is an overgrowth disorder usually (but not always) present at birth characterized by an increased risk of childhood cancer and certain congenital features. Originally, Dr.Hans-Rudolf Wiedemann coined the term exomphalos-macroglosia-gigantism (EMG) syndrome to describe the combination of congenital abdominal wall defects, large tongues, and large bodies and/or long limbs. Over time, this constellation was renamed Beckwith–Wiedemann syndrome following the autoptical observations of Prof. John Bruce Beckwith, who observed also severe increase in the size of the adrenal glands in some of these patients. Five common features used to define BWS are: macroglossia, macrosmia (birth weight and length greater than the 90th percentile), midline abdominal wall defects (omphalocele/exomphalos, umbilical hernia, diastasis recti), ear creases or ear pits, and neonatal hypoglicemia.
