Classically, a 'snowstorm pattern' has been described, resulting from the presence of a complex vesicular intrauterine mass containing many 'grape-like' cysts. Ultrasound evaluation of the adnexa can also reveal theca lutein cysts, due to ovarian stimulation by abnormally elevated beta. Ultrasound is the standard imaging modality for identifying molar pregnancy.

"Snowstorm" pattern demonstrating multiple intrauterine echoes with no fetus seen on transvaginal ultrasonography in a patient with a molar pregnancy. Serum β-hCG was greater than 180,000 mIU/mL. (Photo contributor: Robin Marshall, MD.).
A 27-year-old female presents to the emergency department at 11 weeks of gestation with 2 days of vaginal bleeding and pelvic pressure, as well as multiple daily episodes of nonbloody, nonbilious emesis over the past week. The patient states the bleeding is like heavy spotting with dark purplish. Ultrasound detection of a placental snowstorm appearance with a coexisting viable fetus is a diagnostic and counseling challenge.
The differential diagnosis not only includes partial hydatidiform mole and complete hydatidiform mole with a viable co-twin but also includes placental mesenchymal dysplasia (PMD). Each diagnosis is associated with a different maternal-fetal risk profile, and. The diagnosis of molar pregnancy can nearly always be made by ultrasound, because the chorionic villi of a typical complete mole proliferate with vacuolar swelling and produce a characteristic vesicular sonographic pattern.

It is characterized by punctate patchy or line air bronchogram sign on ultrasound. Snowflake lung consolidation is considered to be the most specific ultrasound imaging feature of RDS.
