Snow Storm or Snowstorm appearance in an ultrasound is the presence of many hydropic villi which gives the ultrasonographic appearance of a central heterogeneous mass having a solid, hyperechoic area and interspersed with a multitude of cystic areas and filling the entire uterine cavity.

An Ultrasound is the standard imaging modality for identifying molar pregnancy.

Classically, a 'snowstorm pattern' has been described, resulting from the presence of a complex vesicular intrauterine mass containing many 'grape-like' cysts.

When MSU crystals are observed in the synovial fluid, a characteristic musculoskeletal ultrasound appearance of multiple hyperechoic foci floating within the joint cavity is described as a “snowstorm appearance.”

Ultrasound imaging uses sound waves to produce pictures of the inside of the body.

It helps diagnose the causes of pain, swelling and infection in the body's internal organs and to examine an unborn child (fetus) in pregnant women.

In infants, doctors commonly use ultrasound to evaluate the brain, hips, and spine. .

The transducer sends high-frequency sound waves through your body.

The waves echo as they hit a dense object, such as an organ or bone.

Those echoes are then reflected back into a computer.

The sound waves are at too high of a pitch for the human ear to hear.

To prepare for an ultrasound.

Eat a low fat dinner on the evening before the examination- (no fried, fatty or greasy foods and no dairy products)
Nothing to eat or drink for 12 hours prior to your appointment.
If there are medications that you must take, only drink a small amount of water when taking the medications.
