Snowstorm sign in obstetric imaging is classically seen in complete hydatiform mole. It is characterized by the presence of many hydropic villi which gives the ultrasonographic appearance of a central heterogeneous mass having a solid, hyperechoic. The snowflake sign.
A sonographic marker for prenatal detection of fetal skin denudation. 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.). We present a case of fetal junctional epidermolysis bullosa in a consanguineous couple, highly suggested by previous obstetric history and several antenatal ultrasound signs, such as polyhydramnios, gastric enlargment, the "snowflake sign", abnormal external ears, signs of skin desquamation, lower limbs anomalies and chorioamniotic membrane.
Download scientific diagram Ultrasound image showing snowstorm pattern of complete hydatidiform mole with a viable co-existing fetus at 14 weeks 3 days. from publication: A case of viable fetus. When a pregnancy is more than 12 weeks and the fetus is intact, it is not difficult to diagnose a partial mole because the typical "snowflake" picture is seen in the placental area accompanying the fetus.
A 27-year-old female presents to the emergency department at 11 weeks of gestation with 2 days of uterine bleeding and pelvic pressure, as well as multiple daily episodes of nonbloody, nonbilious emesis over the past week. The patient states that the bleeding is like heavy spotting with dark, purplish-colored blood. On exam, the uterus is larger than expected for gestational age.
An ultrasound. Complete hydatidiform moles (CHM) are a type of molar pregnancy and fall at the benign end of the spectrum of gestational trophoblastic disease. Epidemiology A complete hydatidiform mole is the most common type of gestational trophoblastic dise.
The "falling snowflakes" sign was described by Saint Martin and Chiesa [2] as a typical sonographic pattern produced by the cystic lesions caused by Echinococcus granulosus. Our article [1], however, does not deal with the more common E. granulosus infection but with the rare multilocular alveolar type, caused by E.
multilocularis. It yields a snowflake-like pattern due to the cystic trophoblast tissue upon ultrasound. A complete hydatidiform mole is normally aborted and removed by dilation and curettage, commonly at or around 8.
